Compliation of Outdated or Deprecated WCAG 2 Techniques #3014

Open a11ydoer opened 1 year ago

a11ydoer commented 1 year ago

We will use this issue to complie outdated or deprecated WCAG 2 resources so that Working Group members can work those later when WCAG 3 migration happens.

fstrr commented 1 year ago

What's being classed as a "resource"? Do you mean things like really outdated Techniques? If so, I'd like to get those removed long before WCAG 3. If you don't mean Techniques, I'll start a separate thread for those as there are quite a few.

C18: Using CSS margin and padding rules instead of spacer images for layout design

We don't need this any more, I think

fstrr commented 1 year ago

C19: Specifying alignment either to the left OR right in CSS

This is a technique to use either text-align:left or text-align:right to align text. We don't need this.

fstrr commented 1 year ago

SCR50: Providing a mechanism to allow users to display moving, scrolling, or auto-updating text in a static window or area and related SCR50 working example.

I don't think I've ever seen anything like this in the wild.

C29: Using a style switcher to provide a conforming alternate version

We don't need this as it is at the moment, but could it be re-written so it's relevant to custom dark modes?

fstrr commented 1 year ago

C23: Specifying text and background colors of secondary content such as banners, features and navigation in CSS while not specifying text and background colors of the main content

We don't need this as it is, but could it be replaced with an article on forced colors?

fstrr commented 1 year ago

C30: Using CSS to replace text with images of text and providing user interface controls to switch.

I don't think anyone uses this technique anymore, and it's not something we should encourage.

fstrr commented 1 year ago

G146: Using Liquid Layout.

This uses floats to create three percentage-based columns. It's not responsive. This could do with a re-write to get it up to date. Oddly, the word "responsive" doesn't appear in the index page of WCAG 2.1 Techniques.

The SMIL Techniques need to either be updated or removed. Does anyone use SMIL at all? I note that the synchronized multimedia working group was closed in 2012.

fstrr commented 1 year ago

Someone who knows about server-side scripting should audit the server-side techniques. There's only five of them, but going to assume they've not been updated since WCAG 2.0.

@fstrr

EPUB 3.3 refers to SMIL 3.0 as Normative references. https://www.w3.org/TR/epub-33/#bib-smil3

We suppose that SMIL3 supersede SMIL2 and SMIL1, but they have been valid W3C Recommendations. I think that these specs should be retired according to the W3C Process Document.
