1.4.1 Use of Color Understanding doc: add note concerning same color case

[scottaohara]

closes #1467

Per the feedback in the thread, the use case of a hyperlink being styled to look no different than adjacent static text would not be a failure of 1.4.1 since there is no difference in color to compare against.

This PR adds a note to call that out.

Additionally this PR makes some corrections to the source code. Namely:

• removes the </meta> and </link> in the header - these are self-closing tags so these shouldn't be there.
• fixes an instance where a list was nested in a p element, which is invalid and was causing the HTML parser to kick it out/created an empty paragraph after the list.

The change is the note circa lines 65-75. All other changes are results of formatting, and do not represent changes to content.

I have a few issues with the note:

• I think the language should explain that this isn't a failure of this SC but might be a failure of others.
• I don't think that "all sighted users" is the best way to identify the group of people for whom an un-styled link would be a poor experience.
• I think it causes more problems than it solves to explicitly call this a "poor experience."
• Editorially, there is also a sentence fragment.

I propose this paragraph instead:

This criterion does not apply to situations where color has <em>not</em>
been used to convey information, indicate an action, prompt a response, or
distinguish a visual element. For instance, a hyperlink which has been
styled to appear no different than the static text surrounding it would not
fail this success criterion, as there would be no color differentiation
between the actionable hyperlink text and the static text adjacent to it.
However, such a design might fail other success criteria or cause other
usability issues for users.

P.S. Would add this as a suggestion, but the paragraph is spread across multiple lines and the GitHubb function for multi-line comments isn't accessible.

that is the baseline assumption for any statement in the understanding documents, really. nothing is ever fully exempt from any other potential failures...so don't think it'd be necessary to explicitly call it out here.

Great point. I'd remove the last sentence of my version entirely then:

This criterion does not apply to situations where color has <em>not</em> been used to convey information, indicate an action, prompt a response, or distinguish a visual element. For instance, a hyperlink which has been styled to appear no different than the static text surrounding it would not fail this success criterion, as there would be no color differentiation between the actionable hyperlink text and the static text adjacent to it.

It was recommended to change: ⬇️ Suggested change

- prompt a response, or distinguish a visual element. For instance, a hyperlink which has been styled to appear no + prompt a response or distinguish a visual element, for instance, a hyperlink which has been styled to appear no

I think the original is better than the edit suggested below I.e. I would keep the comma after response — and I would not glue the example sentence onto the end of the other sentence. I think the proposed change adds complexity and moves us in the opposite direction from plain language
