Not a duplicate of this.
I trying to create two columns on a webpage have different background colours that extend to the screen edges. But the content of the columns needs to stay within the bootstrap boxed width.
It should look like this:
I found this answer which almost worked but the inner content wasn't correctly aligned within the boxed width, especially on large screens over 1600px. It basically ended up looking like:
Below, is a code snippet of the closest I could get to it working, it may be the wrong approach entirely:
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"/>
<div class="container" style="background: bisque;">
<div class="row">
<div class="col-xs-12">
<h1>Normal Boxed Width</h1>
</div>
</div>
</div>
<div class="container-fluid">
<div class="row" style="background-color: aquamarine; padding: 0">
<div>
<div class="col-sm-8 col-sm-offset-1">
<h1>Left Panel</h1>

Answer 1

Bootstrap 5 beta
The concept is still the same in Bootstrap 5. Use a absolute position pseudo element on the column(s) to create the appearance of a container inside a container-fluid...
Bootstrap 5 example
Or, use container-fluid and nest smaller grid columns inside the outer columns with background color...
<div class="container-fluid">
<div class="row">
<div class="col-6 bg-info">
<div class="row justify-content-end">
<div class="col-9"> ... </div>
</div>
</div>
<div class="col-6 bg-danger">
<div class="row justify-content-start">
<div class="col-9"> ... </div>
</div>
</div>
</div>
</div>

Bootstrap 4
The concept is still the same in Bootstrap 4, but the -xs- infix no longer exists.
Bootstrap 4 example
Bootstrap 3 (original answer)
Use another wrapper DIV around a 2nd container...
<div class="container" style="background: bisque;">
<div class="row">
<div class="col-xs-12">
<h1>Normal Boxed Width</h1>
</div>
</div>
</div>
<div style="background-color: aquamarine; padding: 0">
<div class="container">
<div class="row">
<div>
<div class="col-sm-9">
<h1>Left Panel</h1>

</div>
<div class="col-sm-3 gray-background" style="background-color: rebeccapurple;padding: 10px;color:#fff">
<h1>Right Panel</h1>
<p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Ducimus, beatae amet est repellendus optio, exercitationem distinctio quasi ut, sapiente, nihil sed libero facere fugiat eaque numquam nulla mollitia suscipit nobis.</p>
</div>
</div>
</div>
<!-- .row -->
</div>
<!-- .container-fluid -->
</div>
EDIT
Use a psuedo element such as..
.right:before {
right: -999em;
background: rebeccapurple;
content: '';
display: block;
position: absolute;
width: 999em;
top: 0;
bottom: 0;
}
