Create tooltips with pure CSS
Tooltips give users helpful hints when they hover over an element, and this generator produces them using only CSS, with no JavaScript needed. You choose the position, background and text colours, the label text and the corner radius, and the tool outputs a clean, reusable CSS snippet. The tooltip is attached with the after pseudo-element and revealed on hover with a smooth fade, so it adds no markup clutter and performs well.
Apply the generated class to any element and set the tooltip text, then adjust the position so it fits your layout.
Lightweight and accessible by default
Pure-CSS tooltips are fast because they avoid JavaScript and work even when scripts are disabled. They are ideal for simple hints on icons, abbreviations and form fields. For richer, fully accessible tooltips that also appear on keyboard focus, you can extend the snippet to trigger on focus as well as hover, which this generator's structure makes straightforward.
All generation happens locally in your browser, so you can experiment freely and copy the result when it looks right.
Notes on the generated code
Because the css tooltip generator runs entirely in your browser, you can experiment with every option and watch the generated code update instantly, with nothing uploaded and no account required. The output is clean, standards-based CSS that works in any project without external libraries or a build step, so you can paste it straight into your stylesheet and refine it further by hand whenever you need to.

Frequently Asked Questions
Do these tooltips need JavaScript?
No. They use the CSS after pseudo-element and the hover state, so they work with no JavaScript at all.
How do I change the tooltip text per element?
The generated snippet uses fixed text in the CSS. For per-element text, set the content from a data attribute instead, which the structure supports.
Can the tooltip appear on keyboard focus?
Yes. Add the focus state alongside hover in the CSS so keyboard users also see the tooltip, improving accessibility.
Why is my tooltip cut off?
It may overflow its container. Ensure the surrounding elements do not hide overflow, or switch the tooltip to a position with more room.
