Bootstrap provides several classes to change the background colors of your elements easily.
To apply a background color in Bootstrap, you can use the following classes:

Here's an example of using the background color in Bootstrap
<div class="p-3 mb-2 bg-primary text-white">.bg-primary</div>
<div class="p-3 mb-2 bg-primary-subtle text-emphasis-primary">.bg-primary-subtle</div>
<div class="p-3 mb-2 bg-secondary text-white">.bg-secondary</div>
<div class="p-3 mb-2 bg-secondary-subtle text-emphasis-secondary">.bg-secondary-subtle</div>

<div class="p-3 mb-2 bg-success-subtle text-emphasis-success">.bg-success-subtle</div>

<div class="p-3 mb-2 bg-info-subtle text-emphasis-info">.bg-info-subtle</div>
<div class="p-3 mb-2 bg-light text-dark">.bg-light</div>
<div class="p-3 mb-2 bg-light-subtle text-emphasis-light">.bg-light-subtle</div>
<div class="p-3 mb-2 bg-dark text-white">.bg-dark</div>
<div class="p-3 mb-2 bg-dark-subtle text-emphasis-dark">.bg-dark-subtle</div>
<p class="p-3 mb-2 bg-body-secondary">.bg-body-secondary</p>
<p class="p-3 mb-2 bg-body-tertiary">.bg-body-tertiary</p>
<div class="p-3 mb-2 bg-body text-body">.bg-body</div>
<div class="p-3 mb-2 bg-black text-white">.bg-black</div>
<div class="p-3 mb-2 bg-white text-dark">.bg-white</div>
<div class="p-3 mb-2 bg-transparent text-body">.bg-transparent</div>
By adding a .bg-gradient class, a linear gradient is added as background image to the backgrounds.
<div class="p-3 mb-2 bg-primary bg-gradient text-white">.bg-primary</div>
<div class="p-3 mb-2 bg-secondary bg-gradient text-white">.bg-secondary</div>
<div class="p-3 mb-2 bg-success bg-gradient text-white">.bg-success</div>
<div class="p-3 mb-2 bg-danger bg-gradient text-white">.bg-danger</div>
<div class="p-3 mb-2 bg-warning bg-gradient text-dark">.bg-warning</div>
<div class="p-3 mb-2 bg-info bg-gradient text-dark">.bg-info</div>
<div class="p-3 mb-2 bg-light bg-gradient text-dark">.bg-light</div>
<div class="p-3 mb-2 bg-dark bg-gradient text-white">.bg-dark</div>
<div class="bg-success p-2 text-white">This is default success background</div>
<div class="bg-success p-2 text-white bg-opacity-75">This is 75% opacity success background</div>
<div class="bg-success p-2 text-dark bg-opacity-50">This is 50% opacity success background</div>
<div class="bg-success p-2 text-dark bg-opacity-25">This is 25% opacity success background</div>
<div class="bg-success p-2 text-dark bg-opacity-10">This is 10% opacity success background</div>
In the code above, we used the .bg-primary, .bg-success, .bg-danger etc. classes to set the background color of the div as blue, green, red, etc. We also used the .text-white class to set the text color as white, which is more visible against a dark background.
