[css-overflow-4] give scrollbar-gutter the ability to decide whether overlay or classic scrollbars should be used instead of only the user agent

[karl-police]

Apparently, scrollbar-gutter is finished and there's no possibility to create overlay scrollbars with it. Instead, the scrollbar-gutter definition, it says this:

Whether classic scrollbars or overlay scrollbars are used, the appearance and size of the scrollbar, and whether scrollbars appear on the start or end edge of the box, is UA defined.

 

I quote "is UA defined". Google Chrome added an experiment with that which can be toggled on the flags. It is an overlay scrollbar, but though it has some issues, and for some reason they gave it some animation and you can't control the style of it.

 

Why should only the user agent, be able to decide whether they see Classic Scrollbars or Overlay Scrollbars? So that would mean, the user using the browser would go to the settings to change it.

Aren't there ways to do those overlay scrollbars with the help of javascript or something? So why not give the web developer the choice to make those overlay scrollbars happen? But without JS.

What if the user agent wants to use both or let the website decide?

See #6090

See #6090

What am I supposed to see there? This is a different issue, where overflow: overlay doesn't matter anymore.

The issue here is scrollbar-gutter's definition regarding when a classic or an overlay scrollbar should be used.

That there was no implementation interest to have a feature to enforce overlay scrollbars, which is pretty close to what you are asking.

implementation interest from who?

are you saying that there's not enough people requesting to have a feature to enforce overlay scrollbars?

"Implementation interest" means interest from the implementors - that is, browser vendors. In other words, we specifically had some browser vendors object to this as a feature, indicating they would not implement it.

So yeah, #6090 has the details of the conversations that happened around this feature, making this a dupe.

Where can I continue this conversation though?
