This issue is something that I mentioned to Hakon last week - it's kind of a pain to have to split important/legal weighted properties out of the declaration at parse time. What would people think about putting the important/legal moniker on the entire declaration instead of a property declaration, e.g.: H1.foo !important { color:red; font-style: italic } This would seem to simplify the management of important and legal declarations significantly, at least in my opinion. Anyone else? -Chris Chris Wilson cwilso@microsoft.com -[- >---------- >From: Chris Lilley[SMTP:Chris.Lilley@sophia.inria.fr] >Sent: Monday, April 22, 1996 6:49 AM >To: rieger@bse.de >Cc: www-style@w3.org >Subject: 'legal' / 'important' and cascading order > >Wolfgang Rieger writes: > > The following example shows a problem connected with the use of > > 'legal'or 'important' and the cascading order: > > > > Example: > > > > Rule 1: > > > > spec1 { prop1 : value1 !important; > > prop2 : value2; } > > Rule 2: > > > > spec2 { prop1 : value1; > > prop2 : value2 !important; } > > [...] > > However, IMHO there is no big use in being able to specify weight on > > the declaration level.
