There are two ways to add a background in Bootstrap: using built-in CSS classes, such as .bg- (monochrome background) and .bg-gradient- (gradient background); using custom CSS rules, such as setting background-color and background-image properties.
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 examplebg- primary,bg-warning, etc. -
.bg-gradient-*: Add a gradient background to the element, where*can beprimary,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:
<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>Method 2: Use custom CSS
If you need more granular Control, you can also use custom CSS rules to add backgrounds to elements:
body {
background-color: #ccc;
}
.my-background {
background-image: url('image.png');
background-repeat: no-repeat;
background-position: center center;
background-size: cover;
}Usage:
<body class="my-background"></body>
Please note that custom CSS rules have higher priority than Bootstrap's built-in CSS classes.
