CSS Outline Color

Customize the outline’s appearance by changing its color. The outline-color property accepts named colors, HEX, RGB, or HSL values, giving you flexibility to match your site’s theme or accessibility needs.

Choosing Colors

Select a color that provides good contrast with the background, ensuring the outline is easily visible. For example, outline-color: green; or outline-color: #00FF00;.

        .colored-outline {

            padding: 20px;
            font-family: Arial, sans-serif;
            background: #222;
            color: #fff;
        }

    <div class="colored-outline">
        <h2>Bright Green Outline</h2>

Explanation: A bright green outline on a dark background ensures the outline is immediately noticeable, improving clarity and visual emphasis.
