Extend bootstrap row outside the container

Question

We are using Bootstrap 3 on our site and I've got a request on a new template with a design which have some elements that doesn't really follow the bootstrap grid. I've tried to get it to work but haven't succeeded.

I've tried to explain the problem in the image below. Anyone have an idea of how I can solve this?

Answer 1

One option is to use a CSS pseudo ::before element that will resize in height along with the col-lg-6..

#main {
    background: lightgreen;
    height: 100vh;
}

#main > .row {
    height: 100vh;
}

.left {
    background: red;
    position: relative;
    top: 50%;
    transform: translateY(-50%);
}

.left:before {
    left: -999em;
    background: red;
    content: '';
    display: block;
    position: absolute;
    width: 999em;
    top: 0;
    bottom: 0;
}
<div class="container" id="main">
    <div class="row">
        <div class="col-lg-6 left">
            ..
        </div>
    </div>
</div>

Another option is to use an absolute position .container-fluid (full-width) behind the content .container that acts as a "ghost"...

.abs {
    position: absolute;
    right:0;
    top:0;
    bottom:0;
    z-index: 1;
}

<div class="container">
    <div class="row">
        <div class="col-sm-6">
            <h4>Content</h4>
        </div>
        <div class="col-sm-6">
            <!-- space over image -->
        </div>
    </div>
</div>
<div class="container-fluid abs">
    <div class="row h-100">
        <div class="col-sm-6 h-100">
            <!-- empty spacer -->
        </div>
        <div class="col-sm-6 right">
            <img src="//placehold.it/1000x400">
        </div>
    </div>
</div>

Here is a variant of solution. You need to create absolute positioned div, include it into col-xs-6, but this container should have position: static As for screen width 1200px and more container width is 1170px, you can calculate padding-left for floating div: padding-left: calc((100% - 1170px) / 2);

.blk {
    background: lightgreen;
    width: 50%;
    position: absolute;

}
.container {
    background: tomato;
    height: 100vh;
    padding: 40px 0;
}
@media only screen and (min-width: 1200px) {
 .cell {
    position: static;
 }
 .blk {
    left: 0;
    right: 50%;
    padding-left: calc((100% - 1170px) / 2);
 }
}

<div class="container">
<div class="row">
    <div class="col-lg-6 cell">
        <div class="blk">Lorem ipsum dolor</div>
     </div>
  <div class="col-lg-6">Lorem ipsum dolor</div>
</div>
</div>

If you use a grid and position it absolute behind your main content, you can get the background grid to be exactly the same as the foreground grid. You can then use pseudo elements to position the image to stretch to the edge of the screen.

.first .stretch-right::after {
  background: url('https://i.picsum.photos/id/802/1920/1080.jpg?hmac=6P9kWTyEU0oX0KcmjlRcGZwNc5Jb27w2_qqtsqQz-fg') no-repeat;
}
.second .stretch-left::after {
  background: url('https://i.picsum.photos/id/802/1920/1080.jpg?hmac=6P9kWTyEU0oX0KcmjlRcGZwNc5Jb27w2_qqtsqQz-fg') no-repeat;
}
.stretch-right::after {
  content: '';
  background-size: cover !important;
  background-position: center center !important;
  right: 0;
  height: 100%;
  position: absolute;
  left: 0;
}
@media (min-width: 1140px){
  .stretch-right::after {
    right: calc((-1%) - ((100vw - 1140px) / 2));
  }
}
.stretch-left::after {
  content: '';
  background-size: cover !important;
  background-position: center center !important;
  right: 0;
  height: 100%;
  position: absolute;
  left: 0;
}
@media (min-width: 1140px){
  .stretch-left::after {
    left: calc((-1%) - ((100vw - 1140px) / 2));
  }
}
