Tooltips inform the user about the function of an element without taking up space in the interface. The tool generates clean, ready-to-paste CSS tooltip code - you choose the position, color, input animation and border style. No JavaScript, no external libraries, compatible with any browser that supports CSS3.

Tooltip can be placed in four directions: top (above the element), bottom (below), left (on the left), right (after right). Advanced variants: top-left, top-right (corner-anchored tooltip). The direction arrow (::before) automatically rotates to the correct direction with a border-trick.

Entrance and exit animations

Fade-in (opacity: 0→1 + transition): subtle appearance. Slide (translateY/translateX): tooltip slides away from the pointing direction. Scale (transform: scale(0.8)→1): "pop" effect. Transition-delay: prevents flickering when the mouse moves quickly over an element.

Accessibility and ARIA attributes

Tooltip CSS does not replace the native title attribute - it supplements it. For accessibility: role="tooltip" on the bubble element, aria-describedby connecting trigger to tooltip, visibility on focus (not only hover) for keyboard users. Background/text contrast: minimum 4.5:1 (WCAG AA).

Style customization

Background color: any HEX/RGB/CSS variable. Text color: contrasting. Corner rounding (border-radius): 4px (rectangle), 8px (rounded), 50px (pill). Shadow (box-shadow): depth and color. Maximum width (max-width): 200-300px with word-break. Font-size: 12-14px for readability.

FAQ

Does tooltip CSS work on touch devices?

Hover does not exist on touch – tooltip is invisible on smartphones without additional JS support. Alternative approach: use :focus-visible (after tapping) or add a small ⓘ icon as a trigger with aria-expanded. Bottom sheet or popover works better on mobile.

How to make a tooltip with HTML inside (rich tooltip)?

Pure CSS does not allow interactive content in the tooltip (links, buttons). For rich tooltips, use CSS Popover API (new 2024, native HTML), Floating UI (JS), or Radix UI Tooltip (React). Simple HTML (span inside ::after) is possible via attr() but with limitations.

What is the difference between tooltip and popover?

Tooltip: short tooltip (1-2 words), only appears on hover/focus, not interactive. Popover: larger floating layer, can contain buttons, form fields and links, requires clicking. CSS Popover API (Chrome 114+) supports both natively.

How to avoid tooltips being cut off at the edge of the screen?

Problem: tooltip positioned absolute may extend beyond the viewport. CSS solutions: overflow: visible on parent, position: fixed (but loses scrolling context). For reliable positioning, use Floating UI or the new CSS Anchor Positioning (2024).

Does tooltip affect SEO?

Content generated by CSS ::after/content is not indexed by Google. If the tooltip contains important SEO information - place it in HTML (e.g. in a hidden span) or use the title attribute. Tooltips are for UX, they are not a carrier of SEO content.
