This code
HTML
<input type="text" name="category" id="category" value=""> <input type="text" name="category_1" id="category_1" value="" tabindex="1"></div>
Though with repeated efforts starting from adding tabindex, nbsp to css cannot have these two inputs appear on single line.
CSS
<style type="text/css">
input.category {
vertical-align:top;
}
</style>
UPDATE
I think there is a plugin css which is over-ridding this behaviour. I have applied all what you guys said nothing works here is the css. I'm using plugin mcdropdown. Here is the code at start is just the copy of style followed with is is the css copy paste of mcdropdown.css file.
Please let me know how this can be done.
add class="category" for input fields and css:
.category {
float: left;
display: block;
}
#category_1 {
margin-left: 20px; /* or space you want..*/
}
and remove those spaces ( ) not really good way to code :)
Benefit of changing element display to block is that you can set vertical margins and paddings to it when needed.
Example usage with labels could be:
html:
<div class="col1">
<label for="field1">Field1 title</label>
<input type="text" name="field1" id="field1" />
</div>
<div class="col2">
<label for="field2">Field2 title</label>
<input type="text" name="field2" id="field2" />
</div>
<div class="clearfix"></div>
CSS:
.col1 {
float: left;
width: 200px;
}
.col2 {
float: left;
width: 200px;
}
.clearfix:after {
content: " ";
visibility: hidden;
display: block;
height: 0;
clear: both;
}
To get them to display on a single line use the css display attribute to change their display to inline here is how I do it:
<html>
<head>
<style>
#category, #category_1{
display: inline;
}
</style>
</head>
<body>
<input type="text" name="category" id="category" value="">
<input type="text" name="category_1" id="category_1" value="" tabindex="1">
</body>
That should solve your problem and it's really simple to! Have a great day!
They are both inline elements and should appear on the same line by default. Close your input tags appropriately (<input... />) and remove the closing </div> tag:
change
<input type="text" name="category" id="category" value=""> <input type="text" name="category_1" id="category_1" value="" tabindex="1"></div>
to
<input type="text" name="category" id="category" value="" /> <input type="text" name="category_1" id="category_1" value="" tabindex="1" />
You can do that by removing float, and add display:inline-block.
Here: http://jsfiddle.net/xW3tt/2/
Can you try this, By default your elements aligned and dispalyed in single line. If you want to apply any css styling or css properties then you may use as like in below. Added class in input elements class="category"
CSS:
<style type="text/css">
input.category {
float:left;
width:100px;
}
</style>
HTML:
<div style='width:500px;'>
<input type="text" name="category" id="category" value="" class="category">
<input type="text" name="category_1" id="category_1" value="" class="category" tabindex="1">
</div>
This answer is a wild guess operation, Try
Try applying below CSS to over-ride:
input.category {
float:left !important;
margin: 0 !important;
padding:0 !important;
clear:none !important;
}
and apply .category class to both your input (*SEE FIDDLE)

I'm new to HTML and I'm trying to learn how to use forms.
The biggest issue I am having so far is aligning the forms. Here is an example of my current HTML file:
<form>
First Name:<input type="text" name="first"><br />
Last Name:<input type="text" name="last"><br />
Email:<input type="text" name="email"><br />
</form>
The problem with this is, the field box after 'Email' is drastically different in terms of spacing compared to first, and last name. What is the 'proper' way to make it so that they 'line-up' essentially?
I am trying to practice good form and syntax...a lot of people might do this with CSS I am not sure, I have only learned the very basics of HTML so far.
The accepted answer (setting an explicit width in pixels) makes it hard to make changes, and breaks when your users use a different font size. Using CSS tables, on the other hand, works great:
form { display: table; }
p { display: table-row; }
label { display: table-cell; }
input { display: table-cell; }
<form>
<p>
<label for="a">Short label:</label>
<input id="a" type="text">
</p>
<p>
<label for="b">Very very very long label:</label>
<input id="b" type="text">
</p>
</form>
Here's a JSFiddle: http://jsfiddle.net/DaS39/1/
And if you need the labels right-aligned, just add text-align: right to the labels: http://jsfiddle.net/DaS39/
EDIT: One more quick note: CSS tables also let you play with columns: for example, if you want to make the input fields take as much space as possible, you can add the following in your form
<div style="display: table-column;"></div>
<div style="display: table-column; width:100%;"></div>
you may want to add white-space: nowrap to the labels in that case.
Another example, this uses CSS, I simply put the form in a div with the container class. And specified that input elements contained within are to be 100% of the container width and not have any elements on either side.
.container {
width: 500px;
clear: both;
}
.container input {
width: 100%;
clear: both;
}
<html>
<head>
<title>Example form</title>
</head>
<body>
<div class="container">
<form>
<label>First Name</label>
<input type="text" name="first"><br />
<label>Last Name</label>
<input type="text" name="last"><br />
<label>Email</label>
<input type="text" name="email"><br />
</form>
</div>
</body>
</html>
A simple solution for you if you're new to HTML, is just to use a table to line everything up.
<form>
<table>
<tr>
<td align="right">First Name:</td>
<td align="left"><input type="text" name="first" /></td>
</tr>
<tr>
<td align="right">Last Name:</td>
<td align="left"><input type="text" name="last" /></td>
</tr>
<tr>
<td align="right">Email:</td>
<td align="left"><input type="text" name="email" /></td>
</tr>
</table>
</form>
I find it far easier to change the display of the labels to inline-block and set a width
label {
display: inline-block;
width: 100px;
text-align: right;
}
<form>
<label>First Name:</label><input type="text" name="first" /><br />
<label>Last Name:</label><input type="text" name="last" /><br />
<label>Email:</label><input type="text" name="email" /><br />
</form>
You should use a table. As a matter of logical structure the data is tabular: this is why you want it to align, because you want to show that the labels are not related solely to their input boxes but also to each other, in a two-dimensional structure.
[consider what you would do if you had string or numeric values to display instead of input boxes.]
For this, I prefer to keep a correct HTML semantic, and to use a CSS simple as possible.
Something like this would do the job :
label{
display: block;
float: left;
width : 120px;
}
One drawback however : you might have to pick the right label width for each form, and this is not easy if your labels can be dynamic (I18N labels for instance).
using css
.containerdiv label {
float:left;
width:25%;
text-align:right;
margin-right:5px; /* optional */
}
.containerdiv input {
float:left;
width:65%;
}
this give you something like:
label1 |input box |
another label |another input box |
I'm a big fan of using definition lists.
They're easy to style using CSS, and they avoid the stigma of using tables for layout.
<dl>
<dt>Username:</dt>
<dd><input type="text" name="username" /></dd>
<dt>Password:</dt>
<dd><input type="password" name="password" /></dd>
</dl>
It also can be done using CSS and without tables or floats or fixed lengths by changing the content direction to rtl and then back to ltr, but the labels must go after each input.
To avoid this markup reordering, just set the label's text in a data-* attribute and show it using an ::after pseudo-element. I think it becomes much clearer.
Here is an example setting the label's text in a custom attribute called data-text and showing them using the ::after pseudo-element, so we don't mess with markup while changing direction to rtl and ltr :
form
{
display: inline-block;
background-color: gold;
padding: 6px;
}
label{
display: block;
direction: rtl;
}
input{
direction: ltr;
}
label::after{
content: attr(data-text);
}
<form>
<label data-text="First Name">
<input type="text" />
</label>
<label data-text="Last Name">
<input type="text" />
</label>
<label data-text="E-mail">
<input type="text" />
</label>
</form>
Clément's answer is by far the best. Here's a somewhat improved answer, showing different possible alignments, including left-center-right aligned buttons:
label {
padding-right: 8px;
}
.FAligned,
.FAlignIn {
display: table;
}
.FAlignIn {
width: 100%;
}
.FRLeft,
.FRRight,
.FRCenter {
display: table-row;
white-space: nowrap;
}
.FCLeft,
.FCRight,
.FCCenter {
display: table-cell;
}
.FRLeft,
.FCLeft,
.FILeft {
text-align: left;
}
.FRRight,
.FCRight,
.FIRight {
text-align: right;
}
.FRCenter,
.FCCenter,
.FICenter {
text-align: center;
}
<form class="FAligned">
<div class="FRLeft">
<p class="FRLeft">
<label for="Input0" class="FCLeft">Left:</label>
<input id="Input0" type="text" size="30" placeholder="Left Left Left" class="FILeft" />
</p>
<p class="FRLeft">
<label for="Input1" class="FCRight">Left Right Left:</label>
<input id="Input1" type="text" size="30" placeholder="Left Right Left" class="FILeft" />
</p>
<p class="FRRight">
<label for="Input2" class="FCLeft">Right Left Left:</label>
<input id="Input2" type="text" size="30" placeholder="Right Left Left" class="FILeft" />
</p>
<p class="FRRight">
<label for="Input3" class="FCRight">Right Right Left:</label>
<input id="Input3" type="text" size="30" placeholder="Right Right Left" class="FILeft" />
</p>
<p class="FRLeft">
<label for="Input4" class="FCLeft">Left Left Right:</label>
<input id="Input4" type="text" size="30" placeholder="Left Left Right" class="FIRight" />
</p>
<p class="FRLeft">
<label for="Input5" class="FCRight">Left Right Right:</label>
<input id="Input5" type="text" size="30" placeholder="Left Right Right" class="FIRight" />
</p>
<p class="FRRight">
<label for="Input6" class="FCLeft">Right Left Right:</label>
<input id="Input6" type="text" size="30" placeholder="Right Left Right" class="FIRight" />
</p>
<p class="FRRight">
<label for="Input7" class="FCRight">Right:</label>
<input id="Input7" type="text" size="30" placeholder="Right Right Right" class="FIRight" />
</p>
<p class="FRCenter">
<label for="Input8" class="FCCenter">And centralised is also possible:</label>
<input id="Input8" type="text" size="60" placeholder="Center in the centre" class="FICenter" />
</p>
</div>
<div class="FAlignIn">
<div class="FRCenter">
<div class="FCLeft"><button type="button">Button on the Left</button></div>
<div class="FCCenter"><button type="button">Button on the Centre</button></div>
<div class="FCRight"><button type="button">Button on the Right</button></div>
</div>
</div>
</form>
I added some padding on the right of all labels (padding-right:8px) just to make the example slight less horrible looking, but that should be done more carefully in a real project (adding padding to all other elements would also be a good idea).
The traditional method is to use a table.
However, many would argue that tables are restricting and prefer CSS. The benefit of using CSS is that you could use various elements. From divs, ordered and un-ordered list, you could accomplish the same layout.
In the end, you'll want to use what you're most comfortable with.
Hint: Tables are easy to get started with.
Example:
<table>
<tbody>
<tr>
<td>
First Name:
</td>
<td>
<input type="text" name="first">
</td>
</tr>
<tr>
<td>
Last Name:
</td>
<td>
<input type="text" name="last">
</td>
</tr>
</tbody>
</table>
I know this has already been answered, but I found a new way to align them nicely - with an extra benefit - see http://www.gargan.org/en/Web_Development/Form_Layout_with_CSS/
basically you use the label element around the input and align using that and then with css you simply align:
label {
display: block;
position: relative;
}
label span {
font-weight: bold;
position: absolute;
left: 3px;
}
label input,
label textarea,
label select {
margin-left: 120px;
}
<label><span>Name</span> <input /></label>
<label><span>E-Mail</span> <input /></label>
<label><span>Comment</span> <textarea></textarea></label>
you do not need any messy br lying around for linebreaks - meaning you can quickly accomplish a multi-column layout dynamically
the whole line is click-able. Especially for checkboxes this is a huge help.
Dynamically showing/hiding form lines is easy (you just search for the input and hide its parent -> the label)
you can assign classes to the whole label making it show error input much clearer (not only around the input field)
Well for the very basics you can try aligning them in the table. However the use of table is bad for layout since table is meant for contents.
What you can use is CSS floating techniques.
.styleform label{float:left;}
.styleform input{margin-left:200px;} /* this gives space for the label on the left */
.styleform .clear{clear:both;} /* prevent elements from stacking weirdly */
<div class="styleform">
<form>
<label>First Name:</label><input type="text" name="first" />
<div class="clear"></div>
<label>Last Name:</label><input type="text" name="first" />
<div class="clear"></div>
<label>Email:</label><input type="text" name="first" />
<div class="clear"></div>
</form>
</div>
An elaborate article I wrote can be found answering the question of IE7 float problem: IE7 float right problems
Insert input tags inside an unordered lists.Make the style-type none.
Here's an example.
<ul>
Input1
<li> <input type="text" />
Input2
<li> <input type="text" />
<ul/>
Worked for me !
The CSS I used to solve this problem, similar to Gjaa but styled better
It's very simple, and I'm just beginning, but it worked quite nicely
Here is my CSS and HTML, used specifically for a simple registration form with no php code
p {
text-align: center;
}
.styleform label {
float: left;
width: 40%;
text-align: right;
}
.styleform input {
float: left;
width: 30%;
}
<form id="registration">
<h1>Register</h1>
<div class="styleform">
<fieldset id="inputs">
<p><label>Name:</label>
<input id="name" type="text" placeholder="Name" autofocus required>
</p>
<p><label>Email:</label>
<input id="email" type="text" placeholder="Email Address" required>
</p>
<p><label>Username:</label>
<input id="username" type="text" placeholder="Username" autofocus required>
</p>
<p>
<label>Password:</label>
<input id="password" type="password" placeholder="Password" required>
</p>
</fieldset>
<fieldset id="actions">
</fieldset>
</div>
<p>
<input type="submit" id="submit" value="Register">
</p>
</form>
<form>
<div>
<label for='username'>UserName</label>
<input type='text' name='username' id='username' value=''>
</div>
</form>
In the CSS you have to declare both label and input as display: inline-block and give width according to your requirements. Hope this will help you. :)
Simply add
<form align="center ></from>
Just put align in opening tag.
I have a simple form like this:
<form method="post" action="/registration">
<label for="alias">Alias:</label>
<input type="text" name="alias" id="alias">
<br>
<label for="email">E-mail:</label>
<input type="text" name="email" id="email">
<br>
<input type="button" value="registger">
</form>
It works fine, but the I have found out that <br> shouldn't be used for this purpose, as it is only intended to be used with text.
If I remove the <br>, then everything will be rendered on a single line, which I do not want.
What is the correct, most clean way to display name-input pairs in a form with CSS, like this:
Alias: [__field__]
E-mail: [__field__]
[SUBMIT BUTTON]
I'd use divs, which will put the labels and inputs into their own block.
<form method="post" action="/registration">
<div>
<label for="alias">Alias:</label>
<input type="text" name="alias" id="alias">
</div>
<div>
<label for="email">E-mail:</label>
<input type="text" name="email" id="email">
</div>
<input type="button" value="registger">
</form>
I typically would put the input inside of the label (so when you click the label, it focuses the input), and then tell the label to be display: block;.
So,
<form method="post" action="/registration">
<label for="alias">
Alias: <input type="text" name="alias" id="alias">
</label>
<label for="email">
E-mail: <input type="text" name="email" id="email">
</label>
<input type="button" value="registger">
</form>
Then do:
label[for], // just selects labels that have the "for" attribute.
input[type="button"] {
display: block;
// And a bottom margin for good measure :)
margin: 0 0 10px; // shorthand for margin-bottom
}
And that should get you what you want.
You could use divs with corresponding CSS:
.myFrm {
width: 250px;
}
input[type=text] {
float: right;
}
.form-group {
margin-bottom: 10px;
}
.form-group::after {
content: "";
clear: both;
display: table;
}
<form method="post" action="/registration">
<div class="myFrm">
<div class="form-group">
<label for="alias">Alias:</label>
<input type="text" name="alias" id="alias">
</div>
<div class="form-group">
<label for="email">E-mail:</label>
<input type="text" name="email" id="email">
</div>
</div>
<input type="button" value="registger">
</form>
I would just use a bit of css to do the trick. Give each of the labels a display:block;
label {
display: block;
}
You can use container divs around the label and input to group them or else make sure "display: block" is added to the label and input elements.
If you need the label to the left of the input then wrap both with a container div and to give you more control on the positioning you could float the label and input to the left or use flexbox.
You ask:
What is the correct, most clean way to display name-input pairs in a
form with CSS
I interpret your question to be related to matters of performance, code efficiency and maintainability. Since just changing the HTML structure does not address responsiveness in different view-ports, adding bits of CSS may have render blocking features but it does nevertheless makes your application ready for mobile responsiveness. This is how I see it:
form {
display: inline-block;
}
label {
margin: 10px;
font-weight: 600;
}
input{
position: absolute;
left: 15%;
}
input[type=button]{
top: 4%;
}
Note that for mobile viewports you may want to adjust the relative measures with media queries. So the question here is not about writing less code but the main requirements of the application.

I do not want to use hardcoded widths and table tags to generate the layout I want to achieve, but my CSS skills aren't developed quite yet. My layout is as follows:
<div id="container">
<div id="DataType">
Type of Data Request <input type="text" />
</div>
<div id="Arguments" >
Arguments <textarea name="arguments" rows="4" cols="45" ></textarea>
</div>
<div id="TargetEnvironment" >
Target Environment <input type="text" />
</div>
<div id="SubmitButton">
<button id="btnSubmit">Submit Request</button>
</div>
</div>
and I would like to have it behave a certain way with CSS. I can achieve it with tables and hard coded margins, but not with proper CSS. Here is what it currently looks like, and what I want it to look like
Here's a solution using float.
#container {
width: 500px;
}
label {
margin-top: 1em;
display: block;
vertical-align: top;
clear: right;
overflow: auto;
}
input, textarea {
width: 300px;
float: right;
padding: 2px;
}
button {
float: right;
}
<div id="container">
<label id="DataType">
Type of Data Request <input type="text" />
</label>
<label id="Arguments" >
Arguments <textarea name="arguments" rows="4" cols="45" ></textarea>
</label>
<label id="TargetEnvironment" >
Target Environment <input type="text" />
</label>
<label id="SubmitButton">
<button id="btnSubmit">Submit Request</button>
</label>
</div>
You can set the width and use float:right on your inputs.
I don't see any problem in using margins or paddings to separate the lines.
Another tip: use the label tag for the labels of your form.
I am trying to render a html form like this: http://i.imgur.com/V53sv8F.jpg
The problem I am facing are:
I am not able to make the fields go in next line after the label
I haven't been able to get the firld length of first and last combined to be as long as that of the email (or password)
Any help is much appreciated.
HTML Code:
<form>
<label for="Name"><strong> Your Name:</strong></label>
<input type="text" id="Name_First" name="Name_First" required>
<input type="text" id="Name_Last" name="Name_Last" required>
<label for="Email">Email Address:<input type="email" id="Email" name="Email" vrequired></label>
<label for="RegPassword">Password:<input type="password" id="RegPasswordRegPassword" name="RegPassword" required></label>
<form>
JS Fiddle link: http://jsfiddle.net/d6a4h9o8/
For starters, your HTML is wrong, so no solution will work if you don't fix it first. So let's start with that:
<form>
<div class="row">
<label for="Name"><strong> Your Name:</strong></label>
<input type="text" id="Name_First" name="Name_First" />
<input type="text" id="Name_Last" name="Name_Last" />
</div>
<div class="row">
<label for="Email">Email Address:</label><input type="email" id="Email" name="Email" />
</div>
<div class="row">
<label for="RegPassword">Password:</label><input type="password" id="RegPasswordRegPassword" name="RegPassword" />
</div>
<form>
Now that we have proper markup and have added some divs to aid with styling (pay attention to those class="row" divs) we can apply CSS this way:
form {
background:#ccc;
padding:30px;
margin:0 auto;
width:50%
}
form label {
display: block;
}
input {
width:300px;
}
.row {
width:300px;
clear:both;
display:block;
position:relative;
margin:5px auto
}
.row:first-child input {
width:142px;
}
.row:first-child input:last-child {
position:absolute;
right:-5px;
width:144px
}
See fiddle to see the result
Now, there are MANY ways to do it, this is just one, but the most important part is to have your markup fixed, then styling it is really easy.
Here is working example similar to the picture.
HTML
<form>
<label for="Name"><strong> Your Name:</strong></label>
<input type="text" id="Name_First" name="Name_First" required>
<input type="text" id="Name_Last" name="Name_Last" required>
<label for="Email">Email Address:</label>
<input type="email" id="Email" name="Email" vrequired>
<label for="RegPassword">Password:</label><input type="password" id="RegPassword" name="RegPassword" required>
<form>
CSS.
form{
max-width: 500px;
background: #d4d4d4;
padding: 20px;
}
form label {display: block;}
input{padding: 7px 0;font-size: 25px;}
input[type="text"]{width:48.2%;}
input[type="email"],input[type="password"]{width: 98%;}
}
Try this:
label {
display: block;
clear: both;
}
You'll still have to do additional styling, of course.
use
#Name_First {
...
}
to target specific element with your css styles.
and try read through http://www.htmldog.com/guides/css/beginner/applyingcss/
what you want to focus on should be "display" and "width"
Let's say I have an html snippet like this:
<div style="width:300px;">
<label for="MyInput">label text</label>
<input type="text" id="MyInput" />
</div>
This isn't my exact code, but the important thing is there's a label and a text input on the same line in a fixed-width container. How can I style the input to fill the remaining width of the container without wrapping and without knowing the size of the label?
Here is a simple and clean solution without using JavaScript or table layout hacks. It is similar to this answer: Input text auto width filling 100% with other elements floating
It is important to wrap the input field with a span which is display:block. Next thing is that the button has to come first and the the input field second.
Then you can float the button to the right and the input field fills the remaining space.
form {
width: 500px;
overflow: hidden;
background-color: yellow;
}
input {
width: 100%;
}
span {
display: block;
overflow: hidden;
padding-right:10px;
}
button {
float: right;
}
<form method="post">
<button>Search</button>
<span><input type="text" title="Search" /></span>

Update 1: If your website is targeted towards modern browsers only, I suggest using flexible boxes. Here you can see the current support.
Update 2: This even works with multiple buttons or other elements that share the full with with the input field. Here is an example.
as much as everyone hates tables for layout, they do help with stuff like this, either using explicit table tags or using display:table-cell
<div style="width:300px; display:table">
<label for="MyInput" style="display:table-cell; width:1px">label text</label>
<input type="text" id="MyInput" style="display:table-cell; width:100%" />
</div>
I suggest using Flexbox:
Be sure to add the proper vendor prefixes though!
form {
width: 400px;
border: 1px solid black;
display: flex;
}
input {
flex: 2;
}
input, label {
margin: 5px;
}
<form method="post">
<label for="myInput">Sample label</label>
<input type="text" id="myInput" placeholder="Sample Input"/>
</form>
Please use flexbox for this. You have a container that is going to flex its children into a row. The first child takes its space as needed. The second one flexes to take all the remaining space:
<div style="display:flex;flex-direction:row">
<label for="MyInput">label text</label>
<input type="text" id="MyInput" style="flex:1" />
</div>
Easiest way to achieve this would be :
CSS :
label{ float: left; }
span
{
display: block;
overflow: hidden;
padding-right: 5px;
padding-left: 10px;
}
span > input{ width: 100%; }
HTML :
<fieldset>
<label>label</label><span><input type="text" /></span>
<label>longer label</label><span><input type="text" /></span>
</fieldset>

Very easy trick is using a CSS calc formula. All modern browsers, IE9, wide range of mobile browsers should support this.
<div style='white-space:nowrap'>
<span style='display:inline-block;width:80px;font-weight:bold'>
<label for='field1'>Field1</label>
</span>
<input id='field1' name='field1' type='text' value='Some text' size='30' style='width:calc(100% - 80px)' />
</div>
you can try this :
div#panel {
border:solid;
width:500px;
height:300px;
}
div#content {
height:90%;
background-color:#1ea8d1; /*light blue*/
}
div#panel input {
width:100%;
height:10%;
/*make input doesnt overflow inside div*/
-webkit-box-sizing: border-box;
-moz-box-sizing: border-box;
box-sizing: border-box;
/*make input doesnt overflow inside div*/
}
<div id="panel">
<div id="content"></div>
<input type="text" placeholder="write here..."/>
</div>
The answers given here are a bit outdated. So, here I'm with the easiest solution using modern flexbox.
.input-container{
display:flex;
}
input{
flex-grow: 1;
margin-left: 5px;
}
<div style="width:300px;">
<div class="input-container">
<label for="MyInput">label text: </label>
<input type="text" id="MyInput"/>
</div>
<div class="input-container">
<label for="MyInput2">Long label text: </label>
<input type="text" id="MyInput2" />
</div>
</div>
If you're using Bootstrap 4:
<form class="d-flex">
<label for="myInput" class="align-items-center">Sample label</label>
<input type="text" id="myInput" placeholder="Sample Input" class="flex-grow-1"/>
</form>
Better yet, use what's built into Bootstrap:
<form>
<div class="input-group">
<div class="input-group-prepend">
<label for="myInput" class="input-group-text">Default</label>
</div>
<input type="text" class="form-control" id="myInput">
</div>
</form>
