"extends:.page" in template.css about oocss HOT 8 CLOSED

Nope, that's something I'm working on which will eventually have support either via browser vendors/w3c or preprocessing.

Ok. Thanks for quenching my curiosity.

IMHO this is certainly worth mentioning in your FAQ to prevent any confusion. Or, at least as a comment in the CSS-file right after the selector containing the extends-rule. Maybe: "/* 'extends:' is a possible future CSS feature */" or something of a similar meaning.

Do you have a draft or suggestion for its rule definition the same way W3C has?

Thought I'd mention I've added this ability, using this syntax, to my CSS preprocessor - http://github.com/anthonyshort/csscaffold/tree/master

It allows one selector to take on all the properties of another selector in all instances.

@anthonyshort the rendered result would be the same but the problem is that your preprocessor creates (x * y - x) lines/rules of overhead when
x = number of lines/rules the definition has you want to include with 'extend:'
y = number how often you use 'extend:'

to be correct you have to add y rules/lines in the end because 'extend:' is one too.

The overhead is very little, as it compresses/optimizes the css at the end, so duplicate selectors, like what could be created with 'extends', would be merged. For the selectors it can't merge, gzipping should take care of the rest of the overhead.

but you dont have duplicate selectors... you have duplicate properties or? (im not quite sure how you implemented that)
the only style of writing css that could remove duplicate properties is the one-property-per-line style as google uses it.

@mklappstuhl I've written up how I think this should work here: http://www.slideshare.net/stubbornella/css-wish-list

@anthonyshort Ideally this would be in the browser, a significant portion of users have gzip disabled (often due to antivirus software), so relying on compression isn't enough.

In a preprocessor, extends adds a new selector string at the same place in the code as the rule being extended. This means you can make use of CSS built in comma delimited selector string to share rulesets. Only a small portion of the code is duplicated.

Closing this as I've removed that bit of code, we can move any discussion to the google group going forward.
