A CSS tooltip generator helps you create custom tooltips using only HTML and CSS, without JavaScript. You can style the popup, choose its position, colors, and arrow design visually, then copy the ready-to-use code.
Wrap your element with a
position: relative container, and put a span with the tooltip class inside. Use :hover to show the tooltip. Our generator creates exactly that structure for you.
Yes, select Top, Bottom, Left, or Right from the Direction dropdown. The tooltip arrow (created with the
::after pseudo-element) automatically adjusts its position and border color.
The CSS tooltip uses standard properties (position, opacity, transition, and pseudo-elements) supported by all modern browsers, including Chrome, Firefox, Safari, and Edge. For IE11, basic positioning works but transitions may not be fully supported.
Add
aria-describedby to the trigger element and link it to the tooltip. Also, ensure tooltips are visible on :focus-visible for keyboard users. Our preview includes focus support.
