RE: CFC - Changes to Target Size for Issue 631

I would like to check this a bit further as this directly raises the question of different implementations.
Don't have lots of time today but here a plain example of links in lists:


I have 3 lists with links, all with mandatory added padding otherwise I have not enough height for the 26px.
Beneath the list items I have 8 px margin because this is also mandatory, so all lists are save... nice.

BUT, If I have a target size of 34px height for my links (26 + 8) but no spacing in between (like this one better, no flicker when hovering) this is a fail, even 35, 36, 37... etc will fail...?!

Also I've  checked with a couple of designers and they won't like it because at 12 and 14 the distance is just a bit too much.

When we're going this way we should at least define links in lists as part of a block of text.

So far my time now...

Here is what I would propose:

The size of the target for pointer inputs is at least 44 by 44 CSS pixels or is at least 26 by 26 CSS pixels with 8 CSS  pixels spacing between targets except when:

Equivalent - The target is available through an equivalent link or control on the same page that is at least 44 by 44 CSS pixels;
Inline- The target is in a sentence or block of text; User Agent Control - The size of the target is determined by the user agent and is not modified by the author.
Essential- A particular presentation of the target is essential to the information being conveyed;

This is based on the Microsoft research that the MATF looked at.  I am travelling so I can't pull up the study paper.

Hi Kathy,

can you make a quick draft for this?

I guess the problem is that it might be too late for another draft. And we still have the issue of lists of links, in dropdown menus and the like - we would need to have a number what spacing (or target height) we would consider sufficient, and might end up where we were (44x22). Or am I missing something?
