Vendor prefix stats #9

Open LeaVerou opened 4 years ago

LeaVerou commented 4 years ago

Popular vendor prefix numbers. Are the -webkit-, -moz-, -o- or -ms- numbers still relevant, considering the improved browser support for most of the CSS properties that once required vendor prefixes?

Nice one, although -webkit now falls into two categories which should be distinguished;

  1. Things that are actually WebKit specific
  2. Things that the other browsers have (wth varying degrees of reluctance) had to implement, primarily so that iOS-specific mobile content also works on browsers other than Safari. The -webkit vendor prefix merely being historical legacy, at this point.

The second one is interesting to analyze because it constitutes a part of the Open Web Platform that was added without the usual design debate or standards process.

I suppose one way to measure this would be to measure properties starting with -(webkit|moz|ms|apple|o)-, as well as its presence in values (with \B before and [a-z]+ after) and selectors (with : before and [a-z]+ after) and keep track of what we find (properties, values, selectors should be separate), then aggregating over the website corpus will be quite illuminating.

Note that the JS pushed doesn't measure prefixed @-rules: The Rework parser doesn't seem to parse those correctly unless they are known (e.g. @-moz-document).
