Icons

Use this small set of icons that we know our users need and understand to help them identify and navigate content more quickly.

When to use these icons

Use these icons to mark important parts of the page and highlight things you want users to do.

How to use these icons

Use icons sparingly, and not for decoration.

Using text with icons

Some of our icons can be used on their own. Users recognise them easily. They include:

  • search
  • chevron right
  • plus and minus (for reveals)
  • close

Other icons needs an explanation. They include:

  • action links - tell the user what the link will help them do, for example: "Find a pharmacy"
  • right and left arrows for pagination - add "Previous" or "Next"
  • cross and tick - use the words Do and Don't at the top of Do and Don't lists

Using SVG classes for icons

We use scalable vector graphics (SVG) for icons, rather than images such as PNG. SVG are code snippets that you can drop directly into the HTML.

SVG icons are sharp, flexible, and load quickly - and you can control how they appear, for example their colour, with style sheets (CSS).

If you're using a server side or templating language, you can include the icons with include 'partials/icons/icon-search.svg'.

SVG icons have the class .nhsuk-icon, which sets a default size for the icon. Each icon also has a specific class, such as .nhsuk-icon__search. The specific class allows you to modify the icon with styles, such as fill. This means you can change the colour of the SVG for states such as hover, focus and active.

Some older browsers like Internet Explorer 8 can't display SVG. So every SVG icon has a PNG fallback. The fallback images have a class, such as .nhsuk-icon__search—fallback, which you can use to modify their sizing and spacing.

Accessibility

SVG icons must be accessible. For example, they need to meet accessible colour contrast standards. Our recommended tool to test colour combinations is the WebAIM contrast checker. Read more about accessible SVGs on CSS Tricks website.

Research

These icons seem to be universally recognisable. When we tested them, we found that people understood them. We tested them in context - not on their own, but in components on a full page.
