How to add background in Bootstrap

Bootstrap is a popular front-end framework that provides an easy way to add a background to an HTML element. There are two main ways to do this:

Method 1: Using CSS Classes

Bootstrap provides a series of built-in CSS classes that add different Type of background:

.bg-*: Adds a solid color background to the element, where * can be any color, for example bg- primary, bg-warning, etc.
.bg-gradient-*: Add a gradient background to the element, where * can be primary, secondary , success, etc.
.bg-image: Add an image background to the element. The URL or path to the image needs to be specified.

How to use:

<code class="html"><div class="bg-primary">This is a blue background.</div>
<div class="bg-gradient-primary">This is a blue gradient background.</div>
<div class="bg-image" style="background-image: url('image.png');">This is a background image.</div></code>

Method 2: Use custom CSS

If you need more granular Control, you can also use custom CSS rules to add backgrounds to elements:

<code class="css">body {
  background-color: #ccc;
}

.my-background {
  background-image: url('image.png');
  background-repeat: no-repeat;
  background-position: center center;
  background-size: cover;
}</code>

Copy after login

Usage:

<code class="html"><body class="my-background"></body></code>

Copy after login

Please note that custom CSS rules have higher priority than Bootstrap's built-in CSS classes.
