I agree this is very outdated.

It is a support document for WCAG 1.0, while the current version of WCAG 
is 2.1

https://www.w3.org/TR/WCAG21/
W3C Recommendation 05 June 2018

note that https://www.w3.org/TR/WCAG/ resolves to WCAG 2.1, implying 
WCAG 1.0 is superceeded by it?

WCAG 2.1 has it's own support document
https://www.w3.org/WAI/WCAG21/Techniques/
W3C Editor's Draft 22 August 2018

linked from https://www.w3.org/TR/WCAG21/#wcag-2-1-supporting-documents

which includes a CSS section.

I would link to that section, except the document has poor 
accessibility, uses list items instead of headings [see 
https://www.w3.org/WAI/WCAG21/Techniques/general/G141 ] and has no IDs 
so I can't link to the CSS Techniques section, nor does it show up in 
the table of contents.

CSSWG should probably review the WCAG 2.1 CS techniques to be sure that 
they make sense and do not recommend any bad practices or make 
unwarranted assumptions.

Given that though, perhaps the CSS techniques for WCAG 1.0 can be 
obsoleted?
