What is a CSS tooltip?

A tooltip is a small label that appears when a user hovers over or focuses an element, giving extra context — what a button does, what an icon means, or the full text of something truncated. A CSS-only tooltip builds this entirely with pseudo-elements and the :hover state, so it needs no JavaScript, no library, and no extra markup beyond a data attribute holding the text.

How to use the tooltip generator

It is instant:

  • Type the tooltip text and choose where it appears (top, bottom, left, or right).
  • Set the background, text color, radius, and font size, and toggle the arrow.
  • Hover the preview button to see it in action.
  • Copy the CSS and add the class and data-tip attribute to your element.

How the CSS-only tooltip works

The technique uses two pseudo-elements on a positioned element. The ::after pseudo-element pulls its text from a data-tip attribute with content: attr(data-tip) and is positioned above, below, or beside the element. The ::before pseudo-element draws the little arrow using the border triangle trick. Both start hidden and fade in on hover. Because the text lives in a data attribute, you can reuse the same class everywhere and just change the attribute value.

Adding a tooltip to your elements

After pasting the CSS, give any element the tooltip class and a data-tip attribute — for example, a span or button with class="tooltip" data-tip="Save changes". The tooltip appears on hover with no other code. Keep the text short so it fits on one line; the generated CSS uses white-space: nowrap, so very long text is better shortened or handled with a different pattern.

Tooltips and accessibility

Hover-only tooltips are convenient but not accessible on their own: touch users cannot hover, and screen-reader users may not perceive them. For important information, back the visual tooltip with a real title attribute or, better, an aria-label or aria-describedby on the element so assistive technology announces it. Never hide essential content behind hover alone — treat CSS tooltips as a visual enhancement for supplementary hints.

Pro tip

Add a short transition so the tooltip fades in smoothly rather than snapping, which this generator includes. Match the arrow color to the tooltip background so it reads as one shape, and keep tooltips clear of screen edges by choosing a sensible position. For richer arrows and shapes, our Triangle Generator pairs well with this tool.

FAQ

Is this CSS Tooltip Generator free?
Yes. It is completely free, runs in your browser, and requires no account or sign-up.
Do these tooltips need JavaScript?
No. They are pure CSS, using pseudo-elements and the :hover state. You only add a class and a data-tip attribute to your element.
How do I add a tooltip to an element?
Paste the generated CSS, then give your element class="tooltip" and a data-tip attribute with the tooltip text, for example data-tip="Save". It appears on hover automatically.
How do I change the tooltip's position?
Choose top, bottom, left, or right in the generator. It positions the tooltip and its arrow accordingly.
Are CSS tooltips accessible?
Hover-only tooltips are not fully accessible. For important text, also provide a title, aria-label, or aria-describedby so touch and screen-reader users get the information.
Why is my tooltip text cut off?
The CSS uses white-space: nowrap to keep it on one line. Shorten the text, or remove nowrap and set a max-width if you need multi-line tooltips.
Do CSS tooltips work in all browsers?
Yes. They rely on pseudo-elements, attr(), and :hover, which are supported in every modern browser.
