No previous message | Next message →
Hi All,
This has bugged me for a while. Under the techniques for wcag 2.4.5, they
note G125, G126 and G185. When I look at all of them, they all seem to be
saying the same thing.
https://www.w3.org/TR/UNDERSTANDING-WCAG20/navigation-mechanisms-mult-loc.html
The only slight difference I can see is that G185 seems to be saying that
you need to have links on the home page, G126 sounds like it is for small
sites and G125 just talks about links going to where they say.
I have searched everywhere and can't find rationale for these three, can
anyone fill me in?
Cheers
Lisa

Hi Lisa,
Admittedly, the difference is slight.
* G126 requires that each page has links to all other pages of a small site.
* G85 requires that all pages are linked directly from the home page and that each page has a link back to the home page. So G185 does not require each page to have links to all other pages, just a link to the home page. Interestingly there is no upper limit given for what counts as small site.
* G125 seems fairly general and just checks that links to other pages work without saying anything about the hierarchy or requiring a comprehensive listing. So this technique would presumably work in tandem with another technique such as search. if you had a sub page linking back to the section page above (but not to the home page) AND a second option, say, a general search function, SC 2.4.5 would be met.
I admit there is overlap between G126 and G185 but as techniques are informative only anyway and the small-site techniques are rarely used on the kind of sites that are audited for WCAG compliance (at least in my experience), there is probably little harm in not touching these techniques and focusing on the workload related to WCAG 2.1.

Hi Detlev,
Thanks, so it looks like I was on the right track. I have seen sites that
only use the logo as the home page link, so there isn't a text link. From
the way I read G85 that would fail? I advise people to do both, but I see
more sites with just logos these days.
Thanks again,
Cheers
Lisa

How could this be possible with a government website that contains millions of pages? That interpretation would create millions of links on just the homepage itself.
Question: How do government web master handle this?

If the logo has a meaningful alt attriute (or another way of providing an accessible name to non-visual users) I would assume that the test in G185 would pass and the page (when it belongs to a small site) would thus pass SC 2.4.5. Using the logo as home page link is so common that no visible text link would be required in this case.

G185 is a technique that explicitly focuses on small sites with just a few pages - it covers an exception where linking back to home from all pages would be sufficient to meet SC 2.4.5 without a second means of navigation like search or site map. At least this is my understanding. So this technique is clearly not applicable to a site with millions of pages.

Ok so technically there is a link there even with an image logo. For
usability I always recommend a text link, but I was being too picky on that
one!
Thanks again!
