I am currently facing a challenge in trying to override a running transition using pure CSS. The CSS code I have attempted to overwrite the transition with does not seem to work as expected, and I am unable to comprehend the behavior.
Below, you will find an example code featuring 3 links, each followed by a div. Additionally, there are 3 more div elements added for testing purposes.
The issue arises when a new hover occurs, where I desire all hover effects on subsequent boxes to cease while only the current one remains open. It's akin to a menu scenario; upon hovering over a new menu point, I want all other sub-menus to close except for the current one that is opened.
My initial hope was to utilize the
~selector to revert all followingdivelements back to their normal width. Subsequently, thea:hover + divwould expand the width of the appropriate box. However, this approach did not yield the desired outcome.
Upon further investigation, it became evident that the issue lies within the transitions themselves. By removing all transition lines from the code, the result aligns perfectly with expectations but lacks the delays originally intended. For a visual representation, please refer to the following:
- Here is a fiddle showcasing the non-functional code, and
- here is another fiddle with the transition code removed, demonstrating the working functionality albeit lacking delay.
It was discovered that without the transition code, all successive div elements turn red, including the additional ones at the bottom. Conversely, with the transitions in place, only the hovered element turns red, indicating that the ~ selector does not function as intended due to the interfering nature of the transition properties.
Through this exploration, it became apparent that the transitions were causing interference. Deactivating a running transition seemed unattainable, leading to unexpected behavior from the conflicting code snippet rather than its outright ignorance.
This raises the question: What specific aspect of the transition code lines contributes to this peculiar behavior?
To provide insight, the original width before hovering in my actual project is set to 0. Therefore, a successful workaround involves:
a:hover ~ div {
display:none;
}
Instead of resetting the width property, removing it entirely resolves the issue. The inquiry posed earlier delves into understanding the underlying cause behind the complications faced.
