Links, Buttons, & Other Clickable Elements

Make clickable elements large, and put space between them. Avoid clickable page elements that move.

Best Practices


  • Link text: Make the link text describe its purpose and destination. If you are linking to something from an image or icon, supply a title attribute to give people who use screen readers some context.
  • Link styling: To clearly indicate links, underline them when possible. There should be some visual state change other than color when hovering or focusing on links. Do not rely on color or color changes alone to indicate links.
  • Navigation: Users should be able to tab to navigate between links, and active a link by pressing “Enter” on the keyboard. They should be able to activate hover and focus states with either a mouse or a keyboard.
  • Linked Images: Images that are used as the link text for a link should have especially descriptive alt text, as it will be used as the link text for the link by screenreaders. The text of the image’s alt attribute, followed by the word “link” will be announced as the link text for the link.
  • New window or tab: If a link opens a new tab, or takes the user out of the current format or application, that action should be indicated by the link text. It can be disorienting to users – especially those with cognitive, sight, or mobility problems – to unexpectedly open an item in a new format or application. Indicate either via contextual text near the links, or (preferably) with very clear link text, where links lead, and how they will open. If you need to add contextual text to the link text, consider using a nested tag that is visually hidden for sighted users. An example is given below.

Buttons vs. Links

Screen readers handle links slightly differently than they do buttons. All links and buttons are tab-able, but pressing the Space key or Enter triggers a button, whereas pressing the Enter key only triggers a link.

  • Clickable actions: Use buttons to signal clickable actions, such as “download,” “sign up,” or “log out.” You may use links for less popular or less important actions. If you want something that looks and acts like a button, try to always use the button element rather than styling a link like a button.
  • JavaScript Trigger: If you want the user to trigger some kind of Javascript functionality by clicking it, use a button.
  • Navigation: If you want a user to navigate to a new page or to a different target on the same page, use an anchor element <a>.
