Vector sidebar transition is not in sync with logo/content transition.
Closed, ResolvedPublic


  1. Resize the window narrower/wider than 982px.
  2. Observe sidebar contents, logo and content area transition their size and spacing.

The logo and content area transition in sync, but the sidebar is not. In fact, it's not transitioning at all. So when the others have a 250ms transition, the sidebar contents just snap out of sync.

I never understood the transitions.

They come across as someone's excuse to play with CSS transitions/media queries for the first time. They don't actual add much to the experience and I would personally prefer we turn them off.

The fact that patch was introduced a year ago and no one noticed backs up my view that this is the right thing to do.

Whatever. It's not like people are resizing their browsers to witness the glorious animations.

Nevertheless, it hasn't gone unnoticed. It ''screws'' with some absolutely positioned elements on Wikisource for some folks while others seem to think its harmless -- not true when you're trying to faithfully replicate the layout of a printed book for example.

offending css
/*@media screen and (min-width:982px)*/
.mw-body {
    margin-left: 11em;
    padding: 1.25em 1.5em 1.5em 1.5em;
/*@media screen*/
.mw-body {
    margin-left: 10em;
    padding: 1em;
    border: 1px solid #a7d7f9;
    border-right-width: 0px;
    margin-top: -1px;
    background-color: #fff;
    color: #252525;
    direction: ltr;

And fwiw... folks have noticed the same thing happening in mobile-mode at ~768px -- but I'm guessing that is considered normal and was intentional by design.

OK, let's murder it.
