HTML title attribute alternatives

While using the title attribute is an uncomplicated way to provide tooltips, OverLib and CSS tooltips allow multilined and style-rich tooltips.

With JavaScript libraries, we gain tooltips filled with HTML content with exceptional animations. In contrast, pure CSS tooltips grant additional styling and interactions.

Note: Scan your tooltips with Internet Explorer, Firefox v12+, and Chrome 28+ to ensure browser compatibility.

Creating multiline tooltips with CSS

Implementing multiline tooltips can readily be accomplished by encompassing the text within div elements or using <br> tags. The tooltips can then be styled and positioned suitably with CSS.

Positioning and styling

For accessibility and overall impressiveness, your tooltips should be strategically positioned near the table cells and have an impactful presentation (backgrounds and borders are imperative!).

Transitions

Add transitions for a smoother appearance of the tooltip. Transform those boring tooltips into an engaging one with a touch of animation quirks.

Fallback options

Don't forget about vice versa compatibility. Always provide fallback content via the alt attribute or ARIA labels to keep your content comprehensible when CSS or JavaScript are barred.

Tooltip enhancement with JavaScript libraries

Using OverLib or similar JavaScript libraries can accommodate desired tooltips with additional functionality and options beyond the capabilities of native HTML.

Custom layouts

Having granular control over their design allows tooltips to contain a wide range of HTML content, making them adaptable to your application's needs.

Keep user experience in check

Remember, the purpose of tooltips is to enhance the user experience, not to disrupt it. Always make sure your tooltips do not obstruct the user's navigational flow.

Strive for graceful degradation

Remember, not every user will have their JavaScript enabled. Don't forget to provide alternative ways to display those tooltips using the title attribute!
