Whenever I have a wrapper for a textarea, the textarea's height does not match the textarea's height. There's a few pixels of margin at the bottom. Why does this happen and how do I fix it?
E.g.:
<div>
<textarea></textarea>
</div>
The div will be a few pixels taller than the textarea.
Here's a fiddle:
http://jsfiddle.net/0dgjqp3b/
I don't want to explicitly set the height of the parent. The parent should wrap around the textarea even if the textarea resizes.
It's because the textarea element's display is inline-block by default. As a result, its vertical-align property is set to baseline (which is why it isn't aligned as you would expect). The reason there is reserved space at the bottom is for letters such as 'y' or 'j', which hang below adjacent letters/elements.
To resolve this, you can either change the vertical-align property value to something like top, or you could change the display of the textarea to block:
Updated Example
textarea {
vertical-align: top;
}
Updated Example
textarea {
display: block;
}
Add display:block; to the textarea
div {
border: 1px solid red;
}
textarea {
margin: 0;
padding: 0;
display: block;
}
<div>
<textarea></textarea>
</div>
Add display:block to the textarea element.
div {
border: 1px solid red;
}
textarea {
margin: 0;
padding: 0;
display: block;
}
<div>
<textarea></textarea>
</div>
Jsfiddle
My answer uses much of the code in the previous answers but with one new addition.
div{border:1px solid red;display:table;vertical-align:middle;}
textarea{margin:0;padding:0;vertical-align:middle;}
<div>
<textarea></textarea>
</div>
Let me know if there is anything else I can do.

I have the following CSS and HTML snippet being rendered.
textarea
{
border:1px solid #999999;
width:100%;
margin:5px 0;
padding:3px;
}
<div style="display: block;" id="rulesformitem" class="formitem">
<label for="rules" id="ruleslabel">Rules:</label>
<textarea cols="2" rows="10" id="rules"></textarea>
</div>
Is the problem is that the text area ends up being 8px wider (2px for border + 6px for padding) than the parent. Is there a way to continue to use border and padding but constrain the total size of the textarea to the width of the parent?
Why not forget the hacks and just do it with CSS?
One I use frequently:
.boxsizingBorder {
-webkit-box-sizing: border-box;
-moz-box-sizing: border-box;
box-sizing: border-box;
}

The answer to many CSS formatting problems seems to be "add another <div>!"
So, in that spirit, have you tried adding a wrapper div to which the border/padding are applied and then putting the 100% width textarea inside of that? Something like (untested):
textarea
{
width:100%;
}
.textwrapper
{
border:1px solid #999999;
margin:5px 0;
padding:3px;
}
<div style="display: block;" id="rulesformitem" class="formitem">
<label for="rules" id="ruleslabel">Rules:</label>
<div class="textwrapper"><textarea cols="2" rows="10" id="rules"/></div>
</div>
let's consider the final output rendered to the user of what we want to achieve: a padded textarea with both a border and a padding, which characteristics are that being clicked they pass the focus to our textarea, and the advantage of an automatic 100% width typical of block elements.
The best approach in my opinion is to use low level solutions as far as possible, to reach the maximum browsers support.
In this case the only HTML could work fine, avoiding the use of Javascript (which anyhow we all love).
The LABEL tag comes in our help because has such behaviour and is allowed to contain the input elements it must address to.
Its default style is the one of inline elements, so, giving to the label a block display style we can avail ourselves of the automatic 100% width including padding and borders, while the inner textarea has no border, no padding and a 100% width.
Taking a look at the W3C specifics other advantages we may notice are:
no "for" attribute is needed: when a LABEL tag contains the target input, it automatically focuses the child input when clicked;
if an external label for the textarea has already been designed, no conflicts occur, since a given input may have one or more labels.
See W3C specifics for more detailed information.
Simple example:
.container {
width: 400px;
border: 3px
solid #f7c;
}
.textareaContainer {
display: block;
border: 3px solid #38c;
padding: 10px;
}
textarea {
width: 100%;
margin: 0;
padding: 0;
border-width: 0;
}
<body>
<div class="container">
I am the container
<label class="textareaContainer">
<textarea name="text">I am the padded textarea with a styled border...</textarea>
</label>
</div>
</body>
The padding and border of the .textareaContainer elements are the ones we want to give to the textarea. Try editing them to style it as you want.
I gave large and visible padding and borders to the .textareaContainer element to let you see their behaviour when clicked.
If you're not too bothered about the width of the padding, this solution will actually keep the padding in percentages too..
textarea
{
border:1px solid #999999;
width:98%;
margin:5px 0;
padding:1%;
}
Not perfect, but you'll get some padding and the width adds up to 100% so its all good
I came across another solution here that is so simple: add padding-right to the textarea's container. This keeps the margin, border, and padding on the textarea, which avoids the problem that Beck pointed out about the focus highlight that chrome and safari put around the textarea.
The container's padding-right should be the sum of the effective margin, border, and padding on both sides of the textarea, plus any padding you may otherwise want for the container. So, for the case in the original question:
textarea{
border:1px solid #999999;
width:100%;
margin:5px 0;
padding:3px;
}
.textareacontainer{
padding-right: 8px; /* 1 + 3 + 3 + 1 */
}
<div class="textareacontainer">
<textarea></textarea>
</div>
This table hack code works for me in all browsers from IE8+
<td>
<textarea style="width:100%" rows=3 name="abc">Modify width:% accordingly</textarea>
</td>
I was looking for an inline-styling solution instead of CSS solution, and this is the best I can go for a responsive textarea:
<div style="width: 100%; max-width: 500px;">
<textarea style="width: 100%;"></textarea>
</div>
The problem lies in the box-sizing property.
By default, the initial value of the box-sizing property is content-box.
so you have something like this under the hood:
textarea {
border:1px solid #999999;
width:100%;
margin:5px 0;
padding:3px;
box-sizing: content-box;
}
box-sizing: content-box; means that the width of the actual element is equal to the width of the element's content box.
so when you add padding (in this case padding-right and padding-left --> because we are talking about width) and border (in this case border-right and border-left --> because we are talking about width), these values get added to the final width. so your element will be wider than you want.
set it to box-sizing: border-box;. so the width will be calculated like so:
horizontal border + horizontal padding + width of content box = width
in this case, when you add horizontal border and horizontal padding, the final width of element does not change, in fact, the content box will shrink to satisfy the equation.
You can make use of the box-sizing property, it's supported by all the main standard-compliant browsers and IE8+. You still will need a workaround for IE7 though. Read more here.
No, you cannot do that with CSS. That is the reason Microsoft initially introduced another, and maybe more practical box model. The box model that eventually won, makes it inpractical to mix percentages and units.
I don't think it is OK with you to express padding and border widths in percentage of the parent too.
If you pad and offset it like this:
textarea
{
border:1px solid #999999;
width:100%;
padding: 7px 0 7px 7px;
position:relative; left:-8px; /* 1px border, too */
}
the right side of the textarea perfectly aligns with the right side of the container, and the text inside the textarea aligns perfectly with the body text in the container... and the left side of the textarea 'sticks out' a bit. it's sometimes prettier.
For people who use Bootstrap, textarea.form-control can lead to textarea sizing issues as well. Chrome and Firefox appear to use different heights with the following Bootstrap CSS:
textarea.form-conrtol{
height:auto;
}
I often fix that problem with calc(). You just give the textarea a width of 100% and a certain amount of padding, but you have to subtract the total left and right padding of the 100% width you have given to the textarea:
textarea {
border: 0px;
width: calc(100% -10px);
padding: 5px;
}
Or if you want to give the textarea a border:
textarea {
border: 1px;
width: calc(100% -12px); /* plus the total left and right border */
padding: 5px;
}
How about negative margins?
textarea {
border:1px solid #999999;
width:100%;
margin:5px -4px; /* 4px = border+padding on one side */
padding:3px;
}
The value of the padding has a role to play. Using the style you posted:
textarea {
border:1px solid #999999;
width:100%;
margin:5px 0;
padding:3px;
}
The width is already filled up and you have padding left, right to be 3px. So there will be an overflow.
If you change your style to this:
textarea
{
border:1px solid #999999;
width:98%;
margin:5px 0;
padding: 3px 1%;
}
What my styling is doing now is it has a width of 98% and its remaining 2% to complete a 100% and that is why I gave padding left 1% and padding right 1%. With this, the issue of overflow should be fixed
I know how to solve the problem, read the comment Please, I am looking why i have this problem in the first place, it just weird,
Please read the comment in the style code
Problem : I have this weird problem that, input border width is effecting the position of div, for example if i gave border width 5px to input; span will start after 5 px in relation to the parent, and if i give border width 10px to input span will start after 10px from it's parent div?? it kinda consuting, may be i am missing some thing obvious,
Here is the code snippet
.mainDiv {
display: flex;
}
input {
height: 100%;
/*To change understand the problem
just change the border width*/
border: 10px solid blue;
}
div div {
border: 2px solid black;
height: 30px;
/*i can solve it by displaying this
container as flex container as well*/
}
span {
border: 2px solid red;
/*First Edit Display them inline block
and also give height*/
display: inline-block;
height: 30px;
}
<form action="">
<div class="mainDiv">
<div>
<input type="text" required><span>not good</span>
</div>
</div>
</form>
There is a horizontal gap between the input and the span from whitespace. If you remove the whitepsace between the elements, that horizontal gap goes away.
<input type="text" required><span>not good</span>
There is a vertical gap between the top of the parent and the top of the span because the elements are aligned at the baseline of the text. Notice the bottom of the input, inside its border, and the bottom of the span line up.
I have the following problem: I am creating an inline-block element (.content) within a wrapper-div (.wrapper). If there is content in the .content-div, everything works just fine. But if I remove the content from the .content-div, a space gets added below the inline-block-div.
I am not sure why this happens and how to fix it correctly. Note that after manually removing all spaces and line-breaks in my code the problem persists, but setting the font-size to 0 helps.
Also, setting vertical-align: top to the .content-div helps. I am not sure why exactly.
Whats the best way of fixing it? Why does this happen?
Fiddle: https://jsfiddle.net/cjqvcvL3/1/
<p>Works fine:</p>
<div class="wrapper">
<div class="content">not empty</div>
</div>
<p>Not so much:</p>
<div class="wrapper">
<div class="content"></div>
</div>
.wrapper {
background-color: red;
margin-bottom: 20px;
/* font-size: 0; *//* this would fix it, but why? (problem persists after manually removing all spaces and breaks) */
}
.content {
display: inline-block;
height: 20px;
width: 200px;
background-color: green;
/* vertical-align: top; *//* this would fix it, but why? */
}
Update
I have put together a new fiddle. This should better illustrate my problem. How do I get rid of the green line below the textarea?
https://jsfiddle.net/cjqvcvL3/7/
<div class="content"><textarea>Some
Content</textarea></div>
.content {
display: inline-block;
background-color: green;
}
This happens because you specifically give width and height to the .content.
Have you considered using the :empty pseudo selector?
.content:empty {
display: none;
}
https://jsfiddle.net/cjqvcvL3/5/
Setting your the content display to block instead of inline-block fixes the problem.
.content {
display: block;
height: 20px;
width: 200px;
background-color: green;
/* vertical-align: top; *//* this fixes it */
}
This explains why setting vertical-align to top fixes the problem as well:
The vertical-align CSS property specifies the vertical alignment of an
inline or table-cell box.
Here is a working example: jsfiddle
To remove the gap, you have to surround the content div with a wrapper with font-size:0.
The reason is exained here: answer
inline-block
This value causes an element to generate an inline-level block container. The inside of an inline-block is formatted as a block box, and the element itself is formatted as an atomic inline-level box.
inline
This value causes an element to generate one or more inline boxes.
The most important part for this topic would be that the element itself get's formatted not just the content. Every inline-block element will be seen as atomic inline box and thus take up space.
.wrapper2 {
background-color: red;
margin-bottom: 20px;
font-size:0;
}
on setting a padding to an empty textbox it behaves like this:
doing the same with an empty div it behaves like this:
both elements have the same padding, but the textbox is higher than the div.
i suppose that this behavior is, because the textbox assumes that there will be a content (see cursor), but the div does not have a content and so it is not as high as the textbox without content.
how can i achieve that the div will have the same height as the textbox, even without content?
You have to mention height manually to div for input it will tag some default height once it renders
input {
padding:10px
}
div {
border: 1px;
width: 100px;
padding: 10px;
height: 13px;
background-color :#e9e9e9;
}
Demo here
Set a height on it. Block level elements do not have a predefined height while some inline elements do, like an <input>.
div {
height: 16px;
}
div
{
height: 20px;
}
There is no height, if you give some height, then it will be as text-box.
Demo
Since div is a container you will have to specify height.
height:20px; depending on the height of the text box.
For a pure html/css solution:
#div {
height: 20px;
border: 1px solid black;
Width: 150px;
}
<div id="div" style="border: 1 px solid black"></div>
<br />
<input id="input" type="text" />
I have the following CSS and HTML snippet being rendered.
textarea
{
border:1px solid #999999;
width:100%;
margin:5px 0;
padding:3px;
}
<div style="display: block;" id="rulesformitem" class="formitem">
<label for="rules" id="ruleslabel">Rules:</label>
<textarea cols="2" rows="10" id="rules"></textarea>
</div>
