Bootstrap full width sections with graphical backgrounds - html

Question

I am trying to implement a design from my graphic designer, which whilst looks cool is giving me some headaches as i don't know how to implement in bootstrap.
We have a call to action section, which aligns with the 12 column grid system on its left and right extremes.
It also stretches to the view-port edges:
On the left we have red background stretching all the way to the view-port edge.
On the right we have a grey background image stretching all the way to the view-port edge.
I haven't been able to find a search term for what I am looking to achieve let alone where to start (other than have the cta use the background for the entire width, then overlay a left element over the top).
Any idea on how to code the below graphical layout in bootstrap please?
<section class="cta" style="background: grey; position: relative">
<div class="red" style="position: absolute; left: 0; width: 10%; background: red"></div>
<div class="text-outer">
<div class="container">
<div class="row">
<div class="col-xs-6">left</div>
<div class="col-xs-6">right</div>
</div>
</div>
</div>
</section>

Answer 1

Using <div class="container-fluid"> as a starting point; I am guessing at your page's layout. Let's try this:
See below:
.cntn {
border: 1px red solid; /* you can remove this (not needed) */
}
.red {
background-color: red;
text-align: right;
margin: 0; /* optional */
width: 100px; /* adjust to suit your needs */
float: left;
}
.cta {
margin: 0; /* optional */
float: right;
border: 1px solid green; /* you can remove this (not needed) */
}

<!-- make container fluid -->
<div class="container-fluid">
<div class="row">
<!-- heading area: hexagon -->
<div class="red">
<img src="http://placehold.it/100/100" />
</div>
<!-- heading area: call-to-action -->
<section class="cta">
Action
</section>
</div>
<div class="row cntn">
<div class="col-xs-6">left</div>
<div class="col-xs-6">right</div>
</div>
</div>

Answer 2

Simply change 'div class="container"' to 'div class="container-fluid"'

Answer 3

Something like this? Where black should be the grey gradient and max-width:400px could be anything.
.cta {
overflow-x: hidden;
position: relative
}
.text-outer .container {
width: 100%;
max-width: 400px;
background: grey;
z-index: 2;
position: relative;
}
.text-outer:before,
.text-outer:after {
content: "";
position: absolute;
width: 50%;
height: 100%;
top: 0;
}
.text-outer:before {
background-color: red;
left: 0;
}
.text-outer:after {
background-color: black;
right: 0;
}
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="stylesheet"/>
<section class="cta">
<div class="text-outer">
<div class="container">
<div class="row">
<div class="col-xs-6">left</div>
<div class="col-xs-6">right</div>
</div>
</div>
</div>
</section>

I created with 3 divs as Left Center and Right but if you want to use Left and center then create your own class. Probably following will work
.custom {
width:calc(100% - (50% - 768px/2));
}
.custom {
width:calc(100% - leftCellWidth);
}
You can set height of left as per height of hex image.

Answer 5

Use jumbotron class outside the class container for full-width, as explained here.
HTML:
<div class="jumbotron">
<div class="container">
<div class="row">
<div class="red col-xs-4">
</div>
<div class="grey col-xs-8">
</div>
</div
</div>
</div>
CSS:
.red {
background: url('awesomeredimage.png');
background-size: cover;
}
.grey {
background: url('awesomegreyimage.png');
background-size: cover;
}

Answer 6

All your divs should be wrapped in the container div. And as some others have also suggested: container-fluid helps.
Within container fluid you can add a regular container for the rest of your content. My code below explains this.
You could take the easy route and just use the entire cta image you've posted as a clickable image with .img-responsive in a col-xs-12. In that case my fix takes you about 2 minutes:
<section style="background: grey; position: relative">
<div class="container-fluid">
<div class="row">
<div class="col-xs-12">
<img src="/img/cta.jpg" class="img-responsive">
</div>
</div>
<div class="row">
<div class="col-xs-12">
<div class="container">
<!-- All you other content here-->
</div>
</div>
</div>
</div>
</section>
But you could also hack the design into cols, as I try to show in the code snippet below. Of course you need to tweak and decide on the exact sizes yourself.
<section style="background: grey; position: relative">
<div class="container-fluid">
<div class="row">
<div class="col-xs-3 red">
<img src="/img/hexagon.png" class="img-responsive pull-right">
<!--and give this img a negative margin to flow over to the grey area-->
</div>
<div class="col-xs-1 grey-image"></div>
<div class="col-xs-3 grey-image">
<h3 class="text-center">Call to action</h3>
<p class="text-center">Discount etcetera</p>
</div>
<div class="col-xs-5 grey-image">
<button class="btn center-block">Request quote</button>
</div>
</div>
<div class="row">
<div class="col-sm-12">
<div class="container">
<!-- All you other content here-->
</div>
</div>
</div>
</div>
</section>

Use class="container-fluid" instead of class="container" and than do this style:
.container-fluid {
margin-right: auto;
margin-left: auto;
padding-left: 0px;
padding-right: 0px;
}
