Frequently Asked Questions
How do I add the tooltip to my HTML element? +
Add the class "tooltip" to any element and include a child span with class "tooltip-text" containing your tooltip content. The generated CSS handles positioning and the hover animation. The tooltip appears on hover with no JavaScript needed.
Why use CSS-only tooltips instead of JavaScript ones? +
CSS-only tooltips have zero JavaScript overhead, load faster, and work even when scripts are disabled. They are ideal for simple informational tooltips. For complex tooltips that need click triggers or dynamic content, JavaScript solutions may be more appropriate.
Can I change the tooltip position dynamically based on viewport? +
The generated CSS uses a fixed position (top, right, bottom, or left). For viewport-aware repositioning, you would need JavaScript. However, you can generate multiple position variants and use CSS media queries to switch between them at different breakpoints.
How does the arrow triangle work in CSS? +
The arrow is created using CSS borders on a pseudo-element (::after). By setting one border to a solid color and the adjacent borders to transparent, a triangle shape is formed. The arrow size controls how large the triangle borders are.
