Incorporating a background color/shape that extends beyond the boundaries of the container element

While using bootstrap4, I was wondering if it is feasible to incorporate a background color/shape to a header tag that extends beyond the confines of the container class. Consider the following scenario:

<div class="container">
<div class="row">
    <div class="col-md-8">
        <h1>What is Lorem Ipsum?</h1>
        <p>Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.</p>
        <h2>Why do we use it?</h2>
        <p>It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English.</p>
        <p>Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).</p>

This setup currently resembles something like this:

To achieve the effect shown below, how can I add a background color and shape:

I attempted basic changes to the background color but couldn't find much while searching online. Any guidance or assistance in the right direction would be highly appreciated. Thank you.

Creating a background within the container is not feasible.

You can experiment with pseudo-elements and positioning techniques. For instance, add an ::after element to each heading with 'absolute' position, left: -9999px, and apply the background color to the ::after element instead of the heading itself.

To achieve your desired effect, try using the clip-path: polygon property in your code. You can experiment with different polygon properties to customize the shape. Check out this handy tool for testing them out:

Here is an example snippet for your reference:

.shape {
    background-color: black;
    color: white;
    clip-path: polygon(0 0, 80% 0, 83% 100%, 0 100%);
}
