How to use Media Queries In Bootstrap
To implement a custom theme in Bootstrap 5, set the data-bs-theme attribute to a custom value, such as `”gfg”`, on the <html> element. Then, define your custom theme using CSS variables within a style block, overriding Bootstrap’s default variables. This allows you to tailor the appearance of elements according to your desired color scheme and aesthetics.
Example: In this example we demonstrates Bootstrap custom theme by setting data-bs-theme=”gfg”, altering text color to black and background to dark green, providing a unique visual experience.
<!DOCTYPE html>
<!-- Custom theme -->
<html lang="en"
data-bs-theme="gfg">
<head>
<meta charset="UTF-8">
<meta name="viewport" content=
"width=device-width, initial-scale=1.0">
<title>Bootstrap Dark Mode</title>
<link href=

[data-bs-theme="gfg"] {

--bs-body-bg: rgba(34, 36, 35, 0.7); /* Change background color to dark green */
}
</style>
</head>
<body>
<div class="container text-center">

To implement Dark Mode in Bootstrap 5, utilize its built-in dark mode utility classes like ‘bg-dark’, ‘text-white’, and ‘bg-dark’ for backgrounds, text, and borders, respectively.
