Roger,

I have to agree with the others here – links need to be visibly obvious, not just randomly discoverable.

SC 1.4.1 has a clear failure in F73 [1] - Failure of Success Criterion 1.4.1 due to creating links that are not visually evident without color vision

Hi Andrew,

I think where I was having concerns is where you suggest that the ‘discoverability’ of links could be achieved:

               “…by being able to tab to them, or by the cursor changing appearance…”

…whereas I am saying that they should be visibly discoverable without any user/page interaction (obviously screen readers will announce links when they are encountered, whether the user is tabbing or arrowing though the page). Again, for me, links that are in menus are visibly discoverable as the ‘menu paradigm’ is a learned user-interaction: pretty much everyone understands that a menu is a collection of links to other places/pages, so the need for additional link-indication is not too high. (Menus that start being art-for-art’s-sake may be an exception here <grin>)

If I misunderstood what you were saying then sorry.

JF

John,
I think that we are in agreement, am I being stingy in my assessment?

Thanks,

Subject: RE: changing presentation of links

I don’t think I would be as generous as Andrew here. I believe links should be perceivable to all users without first having to hunt for them (using tabbing or mousing), as I believe this is an important consideration for users with cognitive disabilities. To quote Steve Krugg, “Don’t Make Me Think”.

I wouldn’t go so far as to insist on  links *always* being blue or *always* being underlined (I am happy with other strategies that meet the test), and I think there is some latitude in Navigation links in a list (commonly used for persistent navigation menus), but for other in-page links I believe that a visual indicator that does not rely on color alone is critical, and I personally would fail any example that did not meet that minimum bar.

My $.02 worth

I would say none.  Links are identifiable by being able to tab to them, or by the cursor changing appearance, as well as other ways that I’m probably forgetting.  There is an impact on usability, for sure, but I don’t think that you’d fail 1.4.1.

Hi

Many developers now remove the underline from links, and some change the colour of links from the default blue. I know from my observations this can make the pages harder for some people to use.

I would be interested to know what impact other people think this might have on complying with this Success Criteria:
1.4.1 Use of Color: Color is not used as the only visual means of conveying information, indicating an action, prompting a response, or distinguishing a visual element.

Thanks
Roger
