Links are fundamental to web navigation, but their default underlined styling doesn't always align with modern design aesthetics. Whether you're building a sleek marketing site with Next.js or crafting a custom web application, knowing how to control link underlines is essential CSS knowledge.
This guide covers every method for removing link underlines, from basic text-decoration properties to modern CSS approaches, while maintaining accessibility and best practices for your web projects.
What You'll Learn
- The CSS property that controls link underlines
- Multiple methods for removing underlines globally and selectively
- Accessibility considerations for link visibility
- Performance-conscious approaches to link styling
- Common pitfalls and how to avoid them
Understanding the CSS Text-Decoration Property
The text-decoration property is the cornerstone of link underline control in CSS. By default, browsers apply text-decoration: underline to anchor (<a>) elements, creating that familiar underline that signals clickability to users.
The text-decoration property is actually a shorthand for several related properties: text-decoration-line, text-decoration-color, text-decoration-style, and text-decoration-thickness. When you simply want to remove an underline, you'll primarily work with text-decoration-line.
The Four Core Values of Text-Decoration-Line
| Value | Effect |
|---|---|
underline | Line below text (default for links) |
overline | Line above text |
line-through | Strikethrough through text |
none | Removes all text decorations |
In modern web development, particularly with frameworks like Next.js, understanding this property becomes crucial because you're often working with component-based styles where link styling might cascade unexpectedly.
Method 1: Global Link Underline Removal
The simplest approach to removing underlines from all links on your site involves applying text-decoration: none to all anchor elements:
a {
text-decoration: none;
}
This single CSS rule removes underlines from every <a> element on your page. It's efficient, easy to maintain, and works consistently across all modern browsers.
Important: When you remove underlines globally, compensate with other visual cues that indicate interactivity--color changes, hover effects, or different font weights. For optimal website performance, this approach minimizes CSS complexity while providing a clean starting point for custom styling.

Removing link underlines carries significant accessibility implications. The underline is a universal visual convention that signals interactivity, and its absence can confuse users about which text is clickable.
WCAG Guidelines for Link Identification
Web Content Accessibility Guidelines (WCAG) require that links be identifiable through means beyond just color. If you remove underlines, provide equivalent alternatives:
- Consistent color differences from surrounding text
- Hover states that reveal interactivity
- Focus states for keyboard navigation
- Structural patterns indicating linked content
Best Practices for Accessible Link Styling
- Establish a consistent link pattern - Pick a color and stick with it so users learn to recognize links
- Implement clear hover states - Provide feedback confirming interactivity
- Maintain visible focus states - Ensure keyboard navigation works
- Test with contrast checkers - Ensure link colors meet WCAG contrast requirements
/* Accessible focus state */
a:focus {
outline: 2px solid #0066cc;
outline-offset: 2px;
}
/* Color-only identification is not enough */
a {
text-decoration: none;
color: #0066cc; /* Must pair with other indicators */
}
Color-Blindness Considerations
Avoid relying solely on color to indicate links. Users with red-green color blindness may struggle if color is the only differentiator. Always pair color differences with other visual cues like underlines or icons. Following these accessibility best practices ensures your web development projects are inclusive and user-friendly.
Text-Decoration-Thickness
Control underline thickness with CSS for more refined aesthetics.
Text-Decoration-Offset
Adjust the space between text and underline for better visual balance.
CSS Custom Properties
Use CSS variables for consistent link theming across your site.
Transition Effects
Add smooth animations for hover states to enhance user experience.
Summary
Removing underlines from links in CSS is straightforward using the text-decoration: none property, but doing so responsibly requires attention to accessibility and user experience.
