CSS Outline Generator

Build an outline or focus ring style and copy an accessible focus-visible variant.

Style an outline or focus ring

Ring uses outline-offset, so it follows the border radius in modern browsers.
The last rule targets focus-visible, so a ring is drawn for keyboard users without showing on every mouse click.

How to use the CSS Outline Generator

  1. Set the outline width, style, colour and offset.
  2. Adjust the border radius and check the focus ring preview.
  3. Copy the rule, including the focus-visible variant, into your CSS.

Frequently Asked Questions

Common questions about the free online css outline generator.

An outline is drawn outside the element box and takes up no layout space, while a border is part of the box and shifts everything around it.
focus-visible only matches when the browser decides the user needs a visible ring, so keyboard users see it while mouse clicks stay clean.
In current browsers an outline is drawn as a rounded rectangle that follows the border radius, provided the offset is not negative.
It pushes the ring away from the edge of the element. A negative value pulls the ring inside, which can hide part of it.
Yes. Removing the focus indicator without a strong replacement makes a page very hard to use with a keyboard or a switch device.
It lets the browser draw its own native focus ring, which is usually the most familiar and most visible option on form controls.
Pick a colour with at least a three to one contrast ratio against both the element and the page background, so it is visible in every state.
No. The outline is painted outside the box and never changes the layout, so adding it cannot push neighbouring content around.
Yes. The copy button places the whole rule set on your clipboard, ready to paste into a stylesheet and edit to match your selectors.
