Missing CSS optimizations

[SpeednetGroup]

I recently switched from using a home-grown CSS compressor to NUglify and noticed that the minified file size was larger using NUglify.

I then compared the output produced by each and came up with a number of missing CSS optimizations in NUglify.

• The space before !important can be removed.
• Color representations should be converted to words if the word is shorter. For example, #808080 should be gray and #f00 should be red. Same for RGB and other color formats. All colors (except when they include an opacity component) should be reduced to the smaller of either the word or the 6- or 3-digit color code.
• All instances of 0% should be 0.
• border:none should be border:0.
• @supports ( (and other similar queries) should have no space - i.e., @supports(.
• font-weight:bold should be font-weight:700.
• Declarations that use a top, right, bottom, and left size should be reduced by eliminating redundant values. For example, margin:15px 0 0 0 should be margin:15px 0 0.

There might be some others, but this is what I came up with in a first pass.

Ok these are great thanks

Can you break them down into separate issues?

Thanks

I'd be happy to -- but just want to be sure that you want a separate issue for each bullet point above. i.e., create a separate issue for "space before !important", etc.

Yes please

OK, no problem, will do this a bit later.

Closed because each point was separated into its own issue.
