Continuing the discussion from How to pass values to HtmlDialog?:
We used to for
UI::WebDialog be able to insert this into the
<meta http-equiv="MSThemeCompatible" content="yes"/>
which would be ignored on Safari, but use the Windows theme under IE.
As Andreas says, it is also ignored for Chrome. (No big surprise.)
We’ve discussed a common theming CSS file many times in the past.
There may be examples posted in old threads. (Check SketchUcation.)
The system color names have been deprecated in the Cascading Style Sheets, Level 3 (CSS3) recommendation.
So, what to do when CSS3 is the default ?
