Shadow/gradient under close button

[Metaception]

I prefer there to be no close button on the vertical tabs (middle click is preferred), but the naive way of hiding .tab-close leaves a ugly shadow. After some digging, I added was able to find the CSS code:

/* Close button */
.tab-close {
    display: none !important;
}
/* Close button gradient */
.tab:hover:not(.pinned) > .tab-title-wrapper {
    mask-image: linear-gradient(to left, transparent 0, black 2em) !important;
}

I think it would be best if there was some indication that the mask-image is for the close button or there should be a wiki entry explaining it. Especially since the method of applying the gradient seems to change with releases.

I noticed #291 mentioned doing something similar, but the CSS was never added to the wiki.

This is a good addition to the wiki; I've went ahead and added your code here.

Feel free to edit the page and make any changes you like.

Thanks for adding it to the wiki!

In the event that the code changes again and no one else updates the wiki before me, I will update the tweak with newer code.

No problem! Thanks for your useful tweak. :)

There are some upcoming changes over in #328, but it doesn't compromise the CSS in any way.
