How to use Media Queries In Bootstrap

Using Component-Level Color Mode

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.

HTML

<!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=
"https://cdn.jsdelivr.net/npm/bootstrap@5.3.2/dist/css/bootstrap.min.css"
        rel="stylesheet"
        integrity=
"sha384-T3c6CoIi6uLrA9TneNEoa7RxnatzjcDSCmG1MXxSR1GAsXEV/Dwwykc2MPK8M2HN"
        crossorigin="anonymous">
    <style>
        [data-bs-theme="gfg"] {
            --bs-body-color: black; /* Change text color to black */
            --bs-body-bg: rgba(34, 36, 35, 0.7); /* Change background color to dark green */
        }
    </style>
</head>

<body>
    <div class="container text-center">
        <div class="mt-1">
            <h2 class="text-success">
                w3wiki
            </h2>
            <h2>It's custom theme!</h2>
        </div>
    </div>
    <script src=
"https://cdn.jsdelivr.net/npm/bootstrap@5.3.2/dist/js/bootstrap.bundle.min.js"
            integrity=
"sha384-C6RzsynM9kWDrMNeT87bh95OGNyZPhcTNXj1NW7RuBCsyN/o0jlpcV8Qyq46cDfL"
            crossorigin="anonymous">
