HTML+CSS Diffs02 Mar 2014
Our textbooks are frequently hundreds of pages long and use a single CSS file, so making a CSS change can change content in unexpected places.
Again, CSS Polyfills and a little XSLT file makes this easy.
CSS-Diff takes an HTML and CSS file and produces an HTML file with all the styling “baked” in.
Then, the provided XSLT file can compare 2 “baked” HTML files and inject
<span> tags whenever the styles differ.
See the CSS-Diff project to run it from the commandline.
