Long Hover
Recently, I encountered a rather embarrassing CSS oversight. I was developing a website with a narrow sidebar containing icons. Lacking space for descriptive text, the design called for accessible, yet initially hidden, tooltips triggered by a prolonged hover. The tooltip would appear after a three-second hover.
My initial approach involved JavaScript state management:
- A state variable to track tooltip visibility (visible/hidden). This state would update a class on the relevant HTML element.
- Event listeners (
mouseenter
,mouseleave
) to manage the state transitions. - A three-second delay before setting the state to
visible
onmouseenter
. - The tooltip would remain hidden (
mouseleave
).
This was a React project, so using JavaScript state felt natural. However, in retrospect, it proved unnecessarily complex. The mouseenter
and mouseleave
events felt slightly unreliable, and the entire functionality could have been implemented more concisely and efficiently with CSS alone.
The embarrassing realization: I unnecessarily leveraged a JavaScript library when a CSS solution was readily available.
I retained the React UI but removed the JavaScript state management. The solution involved a simple CSS transition-delay
property:
1 2 3 4 5 6 |
|
This elegant one-liner perfectly achieves the desired long-hover effect.
This approach, however, doesn't fully address touch screen accessibility. While screen readers handle the accessible text and desktop users benefit from the tooltips, touch-only users might miss the icon labels. My project targeted large screens, assuming cursor availability, but touch accessibility remains a concern. If the element is a link, the :hover
might activate on the initial tap. If the link leads to a page with a clear title, that might provide sufficient context. Otherwise, JavaScript event handling for touch events remains a viable option.
