    A .css file is a Cascading Style Sheets (CSS) file used to define the presentation of a document written in HTML or XML. CSS describes how elements should be rendered on screen, on paper, in speech, or on other media.

    Creating and Using a .css File

    External CSS

    An external CSS file allows you to change the look of an entire website by modifying just one file. To use an external CSS file, you need to create a .css file and link it to your HTML document using the <link> element inside the <head> section.

    Example of linking an external CSS file:

    <!DOCTYPE html>
    <html>
    <head>
    <link rel="stylesheet" href="mystyle.css">
    </head>
    <body>
    <h1>This is a heading</h1>
    <p>This is a paragraph.</p>
    </body>
    </html>
    Copied!

    Example of a .css file (mystyle.css):

    body {
    background-color: lightblue;
    }
    h1 {
    color: navy;
    margin-left: 20px;
    }
    Copied!

    Internal CSS

    Internal CSS is used when a single HTML page has a unique style. The styles are defined within the <style> element inside the <head> section.

    Example of internal CSS:

    <!DOCTYPE html>
    <html>
    <head>
    <style>
    body {
    background-color: linen;
    }
    h1 {
    color: maroon;
    margin-left: 40px;
    }
    </style>
    </head>
    <body>
    <h1>This is a heading</h1>
    <p>This is a paragraph.</p>
    </body>
    </html>
    Copied!
