Simplification - Flash provision

In trying to simplify the WCAG  I will be posting some thoughts / proposals

 

These have to do with 2.3.1 and 2.3.2 

 

1)  I think that 2.3.1 is easier to read and use if we change  "UNLESS" to
"OR" 

 

2)  I think  2.3.1 and 2.3.2 should be structured and worded similarly

 

3)  I think we should change "components that flash"  to  "anything that
flashes" 

 

 

 

2.3.1 Now reads

 

 

2.3.1 Flash Threshold: Content does not flash more than 3 times in any one
second period unless the flash is below the general flash threshold
<http://w#general-thresholddef>  and the red flash threshold
<http://www.w3.org/WAI/GL/2007/04/flash-proposal.htm#red-thresholddef> .
<http://www.w3.org/WAI/GL/WCAG20/WD-UNDERSTANDING-WCAG20-20070220/Overview.h
tml#seizure-does-not-violate>  

 

 

Proposed new wording

 

 

2.3.1 Three Flashes or Threshold: Content does not contain anything that
flashes more than 3 times in any one second period or the flash is below the
general flash threshold <http://w#general-thresholddef>  and the red flash
threshold
<http://www.w3.org/WAI/GL/2007/04/flash-proposal.htm#red-thresholddef> .
<http://www.w3.org/WAI/GL/WCAG20/WD-UNDERSTANDING-WCAG20-20070220/Overview.h
tml#seizure-does-not-violate>  

 

 

 

This also matches better with  2.3.2 which reads:

 

2.3.2 Flashes < 4: Content does not contain any components that flash more
than three times in any 1-second period.

 

Which I suggest we change to just

 

2.3.2  Three Flashes: Content does not contain anything that flash more than
3 times in any 1-second period.
