Re: Visual Indicators

Here's my most recent attempt to save this SC.

Interactive elements needed to progress or complete a process rely on at
least 3 of the following to differentiate them from static elements:


   -

   Color
   -

   Spacing
   -

   Text effect - outline/underline, bold, italic
   -

   Font size
   -

   Font style
   -

   Fill color
   -

   border/outline (including shadow, glow)
   -

   Icon associated with text


except for the following:

   -

   An underline is sufficient to indicate a link is interactive
   -

   A color difference is sufficient to indicate an element is disabled
   -

   The control is part of a group of controls that has a visual indicator
   for the group

OPTION 4 over here
