Why the input text and password fields are not line up? - html

First: you must see the following picture.
As you see, the red rectangle, the two fields does not line up, there is a little space in the start of the top field, while the next field does not.
Note: this problem occurs in all browsers.
HTML
<body>
<br /><br /><br /><br /><br />
<div id="loginForm">
<form action="login.php" method="post">
<label> Username: <input type="text" name="username" id="username" /></label><br />
<label> Password: <input type="password" name="password" id="password" /></label><br /><br />
<input type="submit" name="sbmtLogin" value="login" />
</form>
</div>
</body>
CSS
body {margin:0; padding:0;}
div#loginForm {width:270px; max-width:270px; margin:0 auto; padding:10px; text-align:center; background-color:#8de3fd;}
div#loginForm input {margin:3px; padding:5px; color:#5b5b5b; width:150px; border:1px solid #9a9a9a;}
div#loginForm input[type=submit] {width:70px;}
How can I fix that problem ?

Why the input text and password fields are not line up?
Username and Password are different length words
How can I fix that problem ?
Use a monospace font
Wrap the words in an element that you set to display: inline-block; width: ??? where ??? is a fixed value.
That element could be the labels.
<label for="username"> Username:</label> <input type="text" name="username" id="username" /></label><br />
<label for="password"> Password:</label> <input type="password" name="password" id="password" /></label>
label {
display: inline-block;
width: 7em; /* adjust to taste */
}
Keep in mind that you will get different fonts on different systems, so give yourself some leeway with the width of the elements if you take the second approach.

"Username:" is slightly wider than "Password:"
That is why they are not aligned.
You want to do something like putting the fields in a table or defined width divs.

It's because the text of Username: is a few pixels longer than Password: ?
You need to close the label tags, so the text is actually in the label (setting the for attribute will also make the inputs selectable by clicking the label)
<body>
<br /><br /><br /><br /><br />
<div id="loginForm">
<form action="login.php" method="post">
<label for="username"> Username:</label> <input type="text" name="username" id="username" /></label><br />
<label for="password"> Password:</label> <input type="password" name="password" id="password" /></label> <br /><br />
<input type="submit" name="sbmtLogin" value="login" />
</form>
</div>
</body>
Then put a common width on the labels with css
div#loginForm form label {
display: inline-block;
width: 200px; // whatever looks best
}

Not all characters of the font has the same width for all fonts. In your case Username is slightly larger than the Password, therefore the alignment issue.
To fix the issue you need to put the labels in a fixed with box
HTML - wrapped each input element in a div
<body>
<br /><br /><br /><br /><br />
<div id="loginForm">
<form action="login.php" method="post">
<div><label>Username:</label><input type="text" name="username" id="username" /></div>
<div><label>Password:</label><input type="password" name="password" id="password" /></div>
<div><input type="submit" name="sbmtLogin" value="login" /></div>
</form>
</div>
</body>
CSS - set width of label and set display to inline-block
body {margin:0; padding:0;}
div#loginForm {width:270px; max-width:270px; margin:0 auto; padding:10px; text-align:center; background-color:#8de3fd;}
div#loginForm input {margin:3px; padding:5px; color:#5b5b5b; width:150px; border:1px solid #9a9a9a;}
div#loginForm input[type=submit] {width:70px;}
#loginForm label { width: 100px; display: inline-block; }

Aligning input fields [duplicate]

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.

How can I style html/form elements using CSS?

I'm trying to create a log in form and my html so far is:
<body id="login">
<div id="wrapper">
<div id="loginform">
<form id ="login" name="login" action = "" method="post" accept-charset="utf-8" class="smart-green">
<h1>Login Form</h1>
<label>
<span>Email Address:</span>
<input id="email" type="text" name="email" placeholder="Enter a valid email address" />
</label>
<label>
<span>Password:</span>
<input id="password" type="password" name="password" placeholder="Password" />
</label>
<label>
<span> </span>
<input type="submit" value="Send" />
</label>
</form>
</div>
</div>
I want to style it using CSS. How can I access:
a) the overall form to change the overall style
b) the email address title and box
c) the button
I have tried using . # > but confused myself now. It's probably a really silly mistake I'm making but I can't figure it out...
Here's how can you access:
a) the overall form to change the overall style
Use #loginform {/* CSS rules */} to address the overall style of the form container. Since there's no other element except the form, it will work as if you were targeting the form itself.
b) the email address title and box
use #loginform label {/* CSS rules */} to target the CSS rules at the label and #email{} to target the email input box. You can re-use this last rule for the other items by adding their IDs (e.g. #email, #password {/* CSS rules */})
c) the button
Use input[type=submit] {/* CSS rules */} to style the submit button.
I solved like this
CSS
<style type="text/css">
form{
text-align: center; /* To align the form center */
background-color: orange; /* sets the background-color to orange */
}
#password{ /* If you use class attribute, use .password{} */
/* to modify this section*/
}
#email{
width: 200px; /* to size the email bar*/
}
#submit_button{
color: #fff; /* Text Color*/
background-color: #5cb85c; /* Background color green*/
border-color: #4cae4c; /* border color light green*/
}
</style>
HTML
<div id="wrapper">
<div id="loginform">
<form id ="login" name="login" action = "" method="post" accept-charset="utf-8" class="smart-green">
<h1>Login Form</h1>
<label>
<span>Email Address:</span>
<input id="email" type="text" name="email" placeholder="Enter a valid email address" />
</label>
<br /><br /><br />
<label>
<span>Password:</span>
<input id="password" type="password" name="password" placeholder="Password" />
</label>
<br /><br /><br />
<label>
<span> </span>
<input id="submit_button" type="submit" value="Send" />
</label> <br /><br /><br />
</form>
</div>
</div>
Or instead you can use "class" or "id" to the form,label and input field to provide them individual style.
Wrapping the label around the input is one way to do things (and it is technically valid), the other way is to use the for attribute. The later is typically considered more acceptable to some because it avoids the need for the extra span.
<form id="loginform" action="" method="post">
<div class="input">
<label for="username">Username</label>
<input type="text" name="username" id="username" />
</div>
<div class="input">
<label for="password">Passowrd</label>
<input type="password" name="password" id="password" />
</div>
<input type="submit" value="Log On" class="btn" />
</form>
Would then be styled like:
.input > label:after /* To place style/content after the label */
{
content: ':';
}
.input > label /* To target the label */
{
display:block; /* Puts the label above the input, just an example */
}
.input > input /* The input. */
{
background: yellow; /* for instance */
}
.input /* The whole input and label pair */
{
margin-bottom: 3px; /* Add space bellow each input, or whatever */
}
Otherwise, nesting the input inside the label removes the need for the for attribute on the label element, and id on input element. So, if we use your HTML:
<body id="login">
<div id="wrapper">
<div id="loginform">
<form id ="login" name="login" action = "" method="post" accept-charset="utf-8" class="smart-green">
<h1>Login Form</h1>
<label>
<span>Email Address:</span>
<input id="email" type="text" name="email" placeholder="Enter a valid email address" />
</label>
<label>
<span>Password:</span>
<input id="password" type="password" name="password" placeholder="Password" />
</label>
<label>
<span> </span>
<input type="submit" value="Send" />
</label>
</form>
</div>
</div>
We could style it like this:
#login > label
{
/* Style for input pair */
margin-bottom: 3px;
}
#login label > span
{
/* Style for the label text */
display:block;
}
#login > label > input
{
/* Style for the input itself. */
background: yellow;
}
Since you're just starting out and just want to see it working, maybe it would be simpler for you to attach an 'id' attribute to each html element, and then access them in your css that way (for the specifics you want to edit, e.g. email title, email input, submit button).
For example:
html
<input id="submitBtn" type="submit" value="Send" />
css
#submitBtn{ color:black }
If this doesnt work,
1.) Clear you cache
2.) Make sure your css file is actually included in your html
3.) Make sure each "ID" on the page attached to an element is unique
if that doesnt work, use your dev tools and fiddle around:
hit (f12) in any browser
First of all I recommend you changing the structure of your code to:
...
<form id="login" name="login" action="" method="post" accept-charset="utf-8" class="smart-green">
<h1>Login Form</h1>
<label for="email">Email Address:</label>
<input id="email" type="text" name="email" placeholder="Enter a valid email address" />
<label for="password">Password:</label>
<input id="password" type="password" name="password" placeholder="Password" />
<input type="submit" value="Send" />
</form>
And then the answers are:
a) access to the form
form#login{
...
}
b) the email address title and box
label[for=email]{
}
input[type=email]{
}
c) access the button
input[type=sbumit]{
...
}

How to set input text be shown inline with css?

I try to make inputs be displayed one after another in line using float: right.
[input][input][input]
But instead of it i see steps:
[input]
[input]
[input]
Do anyone has any suggestions? I use labels in form as following
here is my code:
כותרת נוספת
<label for="pa_passport">מספר ת.ז</label>
<input type="text" name="pa_passport" id="pa_passport" placeholder="מספר ת.ז" /><br />
<label for="pa_firstName">שם פרטי</label>
<input type="text" name="pa_firstName" id="pa_firstName" placeholder="שם פרטי" /><br />
<label for="pa_lastName">שם משפחה</label>
<input type="text" name="pa_lastName" id="pa_lastName" placeholder="שם משפחה" /><br />
<div style="clear:both"> </div>
<label for="pa_city">עיר מגורים</label>
<input type="text" name="pa_city" id="pa_city" placeholder="עיר מגורים" /><br />
<label for="pa_car">מספר רכב</label>
<input type="text" name="pa_car" id="pa_car" placeholder="מספר רכב" /><br />
<label for="pa_city">שנת ייצור</label>
<input type="text" name="pa_year" id="pa_year" placeholder="שנת ייצור" /><br />
<h4 class="faqlike bluecolh2">כותרת נוספת</h4>
<label for="pa_phone">טלפון</label>
<input type="text" name="pa_phone" id="pa_phone" placeholder="טלפון" /><br />
<label for="pa_phone"></label>
<select>
<option>054</option>
<option>052</option>
<option>053</option>
<option>050</option>
<option>08</option>
<option>09</option>
</select>
===UPDATE=====
Here is my scss:
.private_area {
label {
display:none;
}
input[type=text] {
float: right;
}
}
I think this is what you want right?
body { direction:rtl;}
H4 { clear:both; padding:20px 0;}
label { display:inline-block; width: 70px; margin:0 5px 0 0;}
.field { float:right;}

let me know if you have any questions :) בהצלחה
I think the problem is the break statement after each input.

Labels and label styles not working on my form.

I am trying to style my form with labels and the label styles don't seem to work correctly.
Here is what my html looks like for the form:
<h1 class="allpages">Questions or Concerns about Compliance Issues?</h1>
<h3>We welcome all compliments and constructive criticism!</h3>
<form class="webform" action="http://hsc.unm.edu/scripts/cfmailform/cfmailer.cfm" method="post">

My css for this part looks like this:
.allpages {text-align:center;color:#007a86;}
h3{text-align:center;}
.webform {background-color: #eeeeee;
width: 655px; border: solid;
border-color: #e9e9e9;margin-left: auto; margin-right: auto; padding: 15px 0px 15px 17px;}
.webform .label {display:inline-block; width:200px; vertical-align:top; text-align:right;}
label is not a class... it is a tag.
Working CSS for that piece:
.webform label { } /* see .label changed to label */
Also: Your elements were not laid out properly in HTML, some were not even labels.
Fixed fiddle: http://jsfiddle.net/digitalextremist/mt4jK/2/
Excerpt:
.webform label {
width:200px;
vertical-align:top;
text-align:right;
float: left
}
<label for="name">Your Name (optional):</label>
<input name="name" type="text" id="name" value="" />
You created a class selector to reference some tag with class=label

Form alignment acting weird

I am trying to have my forms float right, so that it looks neat when everything is placed next to each other, and it works fine, EXCEPT for the first 2? That is what weirds me out? It works great after the first 2. Here is a screenshot that says it all and my HTML code
<head>
<title>New user</title>
<style type="text/css">
#form_container {
width: 25%;
}
#form_container input {
float: right;
clear: both;
}
</style>
</head>
<body>
<div id="form_container">
<form action="" method="post">
Username: <input type="text" name="username" value="" /><br />
Password: <input type="text" name="username" value="" /><br />
Password again: <input type="text" name="username" value="" /><br />
Password triple: <input type="text" name="username" value="" /><br />
</form>
</div>
</body>
Why is there that "space" between the first and second ones?
Thanks on advance everyone!
It's simply because you are asking for a password 3 times.. the markup doesn't like that and throws a random gap at you.
In all seriousness, there are a few ways to fix this.. the easiest is to set clear:both on the br.. that was causing the gap.
jsFiddle example
br {
clear:both;
}
Also, remove clear:both from #form_container input as that isn't needed anymore.
#form_container input {
float: right;
}
I'd also suggest adding a label to each input for validation purposes.
Restructure your markup a bit to add labels (which you could have anyway), and you can ditch the <br>'s completely. Working example here: http://jsfiddle.net/designingsean/rWfek/1/
HTML:
<div id="form_container">
<form action="" method="post">
<label>Username</label>
<input type="text" name="username" value="" />
<label>Password</label>
<input type="text" name="username" value="" />
<label>Password again</label>
<input type="text" name="username" value="" />
<label>Password triple</label>
<input type="text" name="username" value="" />
</form>
</div>
The important bit of CSS:
label {
float:left;
width:50%;
}
The first answer is fine, but I also suggest wrapping everything in label.
The advantage is that when you click on the label text, 'Username: ', it will automatically put focus in the input box. While this might seem small, it really helps on touch devices, and especially on radio inputs -- try tapping the little 10x10 radio box. Much nicer and more intuitive with label.
<label>Username: <input type="text" name="username" value="" /></label>
and in the CSS:
#form_container label {
display:block;
clear:both;
}
Also, if you didn't already know this, I suggest using <input type="password"/> for passwords.
See this JSFiddle.
