Making button go full-width? - css

Question

I want a button to take up the full width of the column, but having difficulties...
<div class="span9 btn-block">
<button class="btn btn-large btn-block btn-primary" type="button">Block level button</button>
</div>
How do I make the button as wide as the column?

Answer 1

Bootstrap v3 & v4
Use btn-block class on your button/element
Bootstrap v2
Use input-block-level class on your button/element

Answer 2

Why not use the Bootstrap predefined class input-block-level that does the job?
Full-Width Button <!-- BS2 -->
Full-Width Button <!-- BS3 -->
<!-- And let's join both for BS# :) -->
Full-Width Button

Answer 3

Bootstrap / CSS
Use col-12, btn-block, w-100, form-control or width:100%
<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css" rel="stylesheet"/>
<button class="btn btn-success col-12">
class="col-12"
</button>
<button class="btn btn-primary w-100">
class="w-100"
</button>
<button class="btn btn-secondary btn-block">
class="btn-block"
</button>
<button class="btn btn-success form-control">
class="form-control"
</button>
<button class="btn btn-danger" style="width:100%">
style="width:100%"
</button>

Answer 4

In case some are noticing btn-block not working anymore in bootstrap 5.1+:
It was dropped in bootstrap 5.1 (changelog):
Breaking Dropped .btn-block for utilities. Instead of using .btn-block
on the .btn, wrap your buttons with .d-grid and a .gap-* utility to
space them as needed. Switch to responsive classes for even more
control over them. Read the docs for some examples.
You can now make a button full width by adding the class w-100, as the authors do in their official Pricing example page:
<button type="button" class="w-100 btn btn-lg btn-outline-primary">

</button>
Source: https://getbootstrap.com/docs/5.1/examples/pricing/
If you want to make a stack of block buttons, the official docs recommend the following :
<div class="d-grid gap-2">
<button class="btn btn-primary" type="button">Button</button>
<button class="btn btn-primary" type="button">Button</button>
</div>

Answer 5

I simply used this:
<div class="col-md-4 col-sm-4 col-xs-4">
<button type="button" class="btn btn-primary btn-block">Sign In</button>
</div>

Answer 6

use
<div class="btn-group btn-group-justified">
...
</div>
but it only works for <a> elements and not <button> elements.
see: http://getbootstrap.com/components/#btn-groups-justified

Answer 7

You should add these styles to a CSS sheet
div .no-padding {
padding:0;
}
button .full-width{
width:100%;
//display:block; //only if you're having issues
}
Then change add the classes to your code
<div class="span9 btn-block no-padding">
<button class="btn btn-large btn-block btn-primary full-width" type="button">Block level button</button>
</div>
I haven't tested this and I'm not 100% sure what you want, but I think this will get you close.

Answer 8

In Bootstrap 5, the class btn-block doesn't work anymore. But instead, you can add the class w-100 to the button to make it as wide as its container.
<link href="https://cdn.jsdelivr.net/npm/bootstrap#5.0.0-beta2/dist/css/bootstrap.min.css" rel="stylesheet" />
<div class="row"><div class=" col-5 ">
<a class="btn btn-outline-primary w-100 " href="# "><span>Button 1</span></a>
</div><div class="col-5 ">
<a class=" btn btn-primary w-100 weiss " href="# "><span>Button 2</span></a>
</div></div>

Answer 9

I would have thought this would be the most bootstrap-esque way of doing things:
<button type='button' class='btn btn-success col-xs-12'> First buttton baby </button>
All I'm doing is adding the class col-xs-12 to the button.

Answer 10

<div class="col-md-9">
<button class="btn btn-block btn-primary" type="button">Block level button</button>
</div>
In Bootstrap 3, this should be all you need. I believe btn-large was overriding the width of btn-block.

Answer 11

Update 2022:
You have multiple ways to make button full width.
You can add the w-100 to the class.
You can add d-grid and gap-2to a container above the button:
<div class="d-grid gap-2"> <!-- Here -->
<button class="btn btn-primary" type="button">Button</button>
</div>

Answer 12

<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css" rel="stylesheet"/>
<button class="btn btn-success col-12">
class="col-12"
</button>
<button class="btn btn-primary w-100">
class="w-100"
</button>
<button class="btn btn-secondary btn-block">
class="btn-block"
</button>
<button class="btn btn-success form-control">
class="form-control"
</button>
<button class="btn btn-danger" style="width:100%">
style="width:100%"
</button>

Answer 13

We can Use a Block Level Full-Width Button
Create block level buttons—those that span the full width of a parent—by adding .btn-block.
<button type="button" class="btn btn-primary btn-lg btn-block">
Block level button
</button>
<button type="button" class="btn btn-secondary btn-lg btn-block">
Block level button
</button>
