low contrast borders --
https://w3c.github.io/wai-intro-accessibility/fundamentals/accessibility-intro/

<shawn> We are redesigning the WAI website. We plan to announce the
prototype soon (but not yet, so please wait to share info :-).

<shawn> The current design iteration has low contrast underlines under h2s
and around some boxes -- that are mostly in-page contents and "asides" --
with headers. These should be subtle, and thus we do not want them to have
high contrast. Contrast is not necessary, given the headers/headings (and
indentation).

<shawn> For example, please see <
https://w3c.github.io/wai-intro-accessibility/fundamentals/accessibility-intro/
>

<shawn> I just wanted to run this by the Task Force before we announced it,
to get confirmation that this is good accessibility and usability
considering all users.

Shawn: WAI Website is being revised.
...
... Correction: Wants to make sure the WAI pages is usable and accessible
even if the borders can't be seen.

are usable

Jim: Borders are fine.

<allanj> +1 for those borders

<shawn> Jim: subtle ones are fine. important ones are good contrast.

<laura> +1

<shawn> Wayne: OK.

+1 from Wayne

+1 from me

<allanj> close item 1

Jim asks Steve about understanding doc for Hover.

Steve: It is not ready to go.

Jim: There's a survey out to review it.

Steve: Have not yet seen the survey.

Wayne: I noticed a few editorial things in the understanding doc.

<allanj> https://www.w3.org/WAI/WCAG21/Understanding/reflow.html

Wayne: For example, no need to say "complex data tables".

<allanj> understanding survey-
https://www.w3.org/2002/09/wbs/35422/Clearing_Understanding/

Wayne: No reason that table content should overflow the screen.
... Common causes are long URLs, images, and nested tables.
... I can add info about how to present that from happening.

Jim: Anyone object to adding that info?

<allanj> to accept waynes edits type +1

+1

<laura> +1

<steverep_> +1

<alastairc> Just to check - does that modify the SC text? (something we
can't do)

<laura> just the understanding doc.

<alastairc> ok

So, Alastair, +1?

<allanj> TSBVI had a fail because of form controls extending off right side.

<alastairc> Hmm, this isn't correct: "*A simple table cell is one that does
not contain another table."

<alastairc> hold on, dialing..

<laura> wonder if it would be better as a technique.

Jim: I will investigate flexible table cells.

<allanj> find technique for flexible form controls depending on zoom level

<allanj> add technique for data tables and toolbars

Wayne: We could do techniques to get around tables going off the page.

<allanj> current sc text

<allanj> Content can be presented without loss of information or
functionality, and without requiring scrolling in two dimensions for:
Vertical scrolling content at a width equivalent to 320 CSS pixels;
Horizontal scrolling content at a height equivalent to 256 CSS pixels;
Except for parts of the content which require two-dimensional layout for
usage or meaning.

Alastair: Asks Wayne what is meant about "simple" table cell.
... The exception is whether the page can scroll or not rather than if the
table can scroll or not.
... If something requires two dimensional scrolling, it is exempted.

<allanj> add technique for css to word-wrap: break-word for long urls.

Note from John to Alaistair: Wayne gave 3 common causes: long URLs, images,
nested tables.

<allanj> add technique for flexible images (scalable)

Wayne: Understanding doc is not normative. This info will help explain what
we mean.

<allanj> add technique for reflowable tables

<allanj> add technique for avoiding nexted tables

I offer to help Wayne with editorial.

Jim, your voice is quite faint.

Wayne: We could put a max resolution of 300 pixels, but agrees with John
that is not advisable because it would be dependent on screen resolution.

Laura: BBC and Boston Globe are good examples of what Alastair said.

Wayne: Lowest resolution of Mac retina display requires 500% magnification.

<allanj> add technique for zooming and content that disappears (must have a
way - some mechanism to get at all content that was on page before zoom)

Alastair: Window size could be reduced to compensate.

<shawn> Eric Eggert

Wayne: Is it worth making a CSS-unit table?

Alastair: I think that already exists in the CSS specs.
... at least for standard resolutions

Jim: Please review and respond to survey I just listed.

<alastairc> Have a great CSUN, I won't be there I'm afraid

<laura> bye.
