940918 - Opening/closing animation of element at load time are annoying

Status: RESOLVED FIXED

(developer.mozilla.org Graveyard :: Design, defect)

Description

[Jeremie Patonnier :Jeremie]

There is a few element that auto collapse or auto open at load time:
- TOC on tablette mode (auto collapse)
- Quick links sub section (can auto open)

There is a nice animation when the user decide to open or collapse one of those elements. However, those animation are also played when the page s load and the element change state.

This very disturbing while you are reading the page before the load end and suddenly, the page is moving.

Would it be possible to avoid those animation at page load and have the elements immediately in their final state even before the page is fully loaded (technically speaking, could it be possible, at load time, to avoid using JavaScript to turn elements in their final state and relay on CSS without any transition).

As an example, take a look at this page: https://developer.mozilla.org/en-US/docs/Web/API/BluetoothManager

I'm going to experiment with this.  Not promising we'll make this move right away, but worth some time this morning.
