Would prefer to use a single div and make use of -webkit-text-fill-color
|
2010-08-09 21:21:04 +00:00
|
|
|
-webkit-text-stroke and text-shadow styles, but they have problems working/
|
|
|
|
|
co-operating in qwebkit. https://bugs.webkit.org/show_bug.cgi?id=43187
|
2010-09-01 21:36:02 +00:00
|
|
|
Therefore one for text, one for outline and one for shadow.
|
|
|
|
|
|
|
|
|
|
Note, the webkit fill problem is fixed in 433.3 and the shadow problem looks
|
|
|
|
|
as though it'll be fixed in QtWebkit 2.1 (434.3)
|
|
|
|
|
There is an alignment problem with fills in 433.3 however requiring a hack
|
|
|
|
|
by setting letter spacing. This is also fixed in v434.3
