CSS search-text Pseudo-Element Style Your Browsers Find in Page Results

Why Style Browser Search?

Have you ever wanted to give your users a more branded or accessible experience when they use the browser's built-in "Find in Page" feature (Ctrl+F / Cmd+F)? The CSS ::search-text pseudo-element, now widely supported across browsers, lets you do exactly that. It targets the highlighted text that appears when a user searches for a term on your page.

This isn't just about aesthetics. Proper styling can improve readability, maintain contrast accessibility (WCAG), and even provide visual cues for the currently focused match using the :current pseudo-class. Let's dive into how it works.

How to Use ::search-text

The syntax is straightforward. You can apply it globally or to specific elements:

/* Style all search matches on the page */
::search-text {
  background: oklch(87% 0.17 90); /* yellow */
  color: black;
}

/* Style only matches inside <section> elements */
section::search-text {
  text-decoration: underline wavy blue;
}

/* Style the currently focused match */
::search-text:current {
  background: oklch(62% 0.22 38); /* red */
  color: white;
}

Supported CSS Properties

You're limited to a specific set of properties to ensure consistent behavior across browsers:

• background-color
• color
• text-decoration and its sub-properties (text-decoration-color, text-decoration-line, text-decoration-style, text-decoration-thickness, text-underline-offset, text-underline-position)
• text-shadow
• Custom properties (var())

Inheritance Chain

Styles applied via highlight pseudo-elements cascade down the DOM tree. For example:

article::search-text {
  background: gold;
  color: black;
  text-decoration: underline;
}

p::search-text {
  color: orange; /* overrides color for <p> and descendants */
}

strong::search-text {
  text-decoration: line-through; /* overrides for <strong> descendants */
}

This means you can set a base style on a parent and selectively override properties on child elements.

Accessibility & Best Practices

While ::search-text is a powerful tool, use it with care:

• Contrast Ratio: Ensure a minimum of 4.5:1 between text and background colors (WCAG AA).
• Subtlety: Avoid drastic changes that might confuse users. Sticking to text-decoration modifications is often the safest approach.
• :current Focus: Use the :current pseudo-class to clearly indicate which match is currently active, especially helpful for users with cognitive disabilities.

What About :past and :future?

The specification reserves :past and :future for future use, but currently combining them with ::search-text is considered invalid. If you see unexpected behavior, report it to the browser vendor.

Browser Support

::search-text enjoys wide support across all major browsers (Chrome, Firefox, Safari, Edge). It's defined in the CSS Pseudo-Elements Module Level 4 specification, which is still being refined.

Limitations & Caveats

• Not all CSS properties are allowed (e.g., border, padding, font-size are unsupported).
• Over-customization can break user expectations – the browser's default highlight is a familiar UX pattern.
• The :current pseudo-class is essential for multi-match navigation, but it's easy to overlook.

Next Steps

Experiment with ::search-text in your next project. Start small: add a subtle underline or a custom color that matches your brand. Test with different search terms and ensure the contrast is accessible. For more advanced styling, explore how custom properties can dynamically adjust themes.
