What Is CSS Tooltip Generator?

The CSS Tooltip Generator creates pure CSS tooltips that require no JavaScript. Tooltips provide additional information when users hover over or focus on elements, making them essential for accessible web interfaces. This tool lets you customize the tooltip position (top, bottom, left, or right), background and text colors, font size, padding, border radius, and arrow size. The tooltip arrow is created using CSS border tricks, and the positioning is handled with absolute positioning relative to the parent element. The generated code includes the wrapper, tooltip, and arrow pseudo-element styles, giving you a complete, self-contained tooltip solution. The preview shows the tooltip always visible so you can see your styling changes in real-time.

Why Use CSS Tooltip Generator?

  • Pure CSS solution with no JavaScript dependencies required
  • Four position options with properly oriented arrows
  • Complete customization of colors, sizing, and spacing
  • Generated code includes wrapper, tooltip, and arrow styles

Technical Guide

CSS tooltips use absolute positioning within a relatively positioned wrapper. The tooltip element is positioned using top/bottom/left/right and transform for centering. The arrow is created using the ::after pseudo-element with the CSS border triangle technique—by setting transparent borders on three sides and a colored border on one side, a triangle shape is formed. The tooltip is shown/hidden using the :hover pseudo-class on the wrapper, with display or visibility controlling visibility. For accessibility, consider adding role="tooltip" and aria-describedby attributes. The white-space: nowrap property prevents text wrapping in short tooltips. For longer content, set a max-width and remove white-space. Transitions can be added for smooth show/hide animations using opacity and transform.

Tips & Best Practices

  • 1
    Add a slight delay before showing to prevent accidental triggers
  • 2
    Use aria-describedby for screen reader accessibility
  • 3
    Keep tooltip text concise—ideally under 150 characters
  • 4
    Test tooltip positioning near screen edges to prevent clipping

Frequently Asked Questions

Q Do CSS hover tooltips work on mobile?
CSS :hover tooltips work on mobile with a tap, but consider using JavaScript for better touch interaction control.
Q How do I add a delay before showing?
Add transition-delay to the tooltip visibility and opacity properties for a delayed appearance.
Q Can I make the tooltip stay visible on hover?
Yes, apply the :hover pseudo-class to the tooltip element itself in addition to the wrapper.
Q Are CSS-only tooltips accessible?
For full accessibility, add ARIA attributes. CSS-only solutions may not be sufficient for screen readers.
Q How do I prevent the tooltip from being cut off?
