HTML, CSS & accessiblity knowledge levels

Emil Stenström has started it, by his article levels of CSS knowledge followed by Roger Johansson writing about Levels of HTML knowledge and finally Joe Clark's Levels of Accessibility Knowledge.

They are all so true and convincing why don't you check your levels and work on giving each a push only if you need it if creating web sites is part of your job.

I consider my self on level 5 of HTML knowledge, also level 5 in CSS knowledge & 4 in accessibility, maybe I should push it more on accessibility, how about you ?

Zoom layouts update

I was away for about a month for some reasons and I just read Joe Clark's article Zoom layouts update I'm glad to be mentioned as one of the first few to apply Joe's zoom layout technique.

Joe commented on my link ( needs fine-tuning for overlapping layout components ) thanks Joe for pointing out the bug for me. It affects Safari only as far as I can see, the reason this bug appears is the negative margin values in the default style which I call it modern that affect other styles when switched to them.

As you can see I have one default style modern and two alternate new & zoom the margin in modern is #top { margin-top: -119px; } the negative values only the negative values affect the alternate styles when switched to them even if there is a rule that overwrite it like #top { margin-top: 0; } to fix the problem I have to overwrite it with a rule like #top { margin-top: -1px; } and maybe let the first object above #top push it one more px to the bottom.

I don't know if this is the best solution but it is one. Thanks a lot Joe and thanks all.

Zoom layouts

First of all you might like to read this article in a Zoom layout, switch styles right on the "Choose style panel" at the left side.

Low vision users, which are a lot more than blind users, need special needs so that they can read and navigate a web site, CSS can provide all these needs.

Aries Arditi ,PhD has been studying web accessibility for 15 years, he come up with "Low vision wish list" which is:

  1. Make it large enough but not too large.
  2. Enhance the contrast.
  3. Enhance the colour contrast.
  4. Present text all on one line.
  5. Increase spacing between letters.
  6. Let me choose my font.
  7. Let me control my reading speed.
  8. Let me see where what I’m reading fits into the big picture.
  9. Grant [the foregoing wishes] for any Web site.

Joe Clark has revealed a new technique in @media 2005 that provide most of this wish list, it is Zoom layout a single column layout with the navigation simplified and placed at the top, fonts become bigger but not too big, contrast enhanced between Background and text.
