TLDR

To quickly create a CSS-only tooltip, pair a div with a hidden span. Make the span visible during a hover event:

<div class="tooltip">Hover me <span class="tooltiptext">Tooltip info</span> </div>
.tooltip { position: relative; display: inline-block; } .tooltip .tooltiptext { /* Invisible at first, like my weekend plans */ visibility: hidden; background-color: black; color: white; text-align: center; border-radius: 6px; padding: 5px; position: absolute; z-index: 1; top: 100%; left: 50%; transform: translateX(-50%); opacity: 0; transition: opacity 0.3s; } .tooltip:hover .tooltiptext { /* Pops up faster than toast! */ visibility: visible; opacity: 1; }

This simple and lightweight approach reveals the tooltip via a smooth fade-in effect on hover without any need for JavaScript.

Upgrade your tooltip: JavaScript style

When additional interactivity or behavior complexity is required, JavaScript or jQuery comes to the rescue to advance the tooltip game. Here's how:

  • Dynamic Content: JavaScript can refresh tooltip content dynamically, responding to user actions or other events. Data attributes or API calls can be leveraged to achieve this.

  • Interactive Positioning: To respond to the mouse cursor or prevent obstruction of other elements, you can use the pointer-events: none; CSS property or use JavaScript for dynamic positioning.

  • Persistent Tooltip: In cases where you want the tooltip to hang around a bit longer, consider a data-tooltip-persistent attribute and use JavaScript to keep the tooltip visible as required.

  • Animation Effects: Go beyond simple CSS transitions with fade, slide, or even bounce animations to improvise the visual experience.

Here's an example utilizing the ::before pseudo-element to create a tooltip:

[data-tooltip]::before { content: attr(data-tooltip); position: absolute; /* As invisible as a ninja */ opacity: 0; transition: opacity 0.3s; pointer-events: none; } [data-tooltip]:hover::before { /* Ta-da! And the tooltip appears */ opacity: 1; }

If you're using JavaScript for tooltips, remember to keep a basic title attribute tooltip as a fallback for users with disabled JavaScript.

Better styling with CSS

Design unique tooltips that are both eye-catching and functional by leveraging the following tips:

  • Consistency: Use matching padding, coloring and font styling that align with your overall web design.

  • Responsiveness: Ensure tooltips adjust or reposition themselves on different screen sizes to avoid overlaps or parts going off-screen.

  • Accessibility: Ensure keyboard users and screen readers correctly access the tooltip content. ARIA attributes help bridge the gap in such situations.

Here's an example showcasing some advanced styling of a tooltip:

.tooltip { /* Make it the belle of the ball */ } .tooltip::before { /* Arrow or pointer styling - guide users like a compass! */ }

Masters of tooltips: JavaScript and jQuery

When taking tooltips to the next level, JavaScript and jQuery plugins wield the power you need:

  • jQuery Tooltip: An established plugin offering tooltips with predefined animations (fade or slide), making it more interactive.

  • Tippy.js: This tooltip library presents a range of options for custom animations and extended theming possibilities.

  • Popper.js: If positioning perfection is what you need, Popper.js provides tooltips that always look like they're in the right place.

Remember to include only what's necessary, prioritizing performance, user experience, and accessibility.
