fix(inlineStyles): empty css block created empty attribute #1823

@SethFalco SethFalco commented Nov 7, 2023

When running this plugin on an SVG with an empty block in the CSS, it would apply it to the matched elements by adding an empty style attribute. See the test for an example.

This resolves that by just dropping the declaration if it's empty.

Chores

I've also done some chores on the side.

  • Exposed compareSpecificity from lib/styles.js and uses that in the Inline Styles plugin.
  • Fixed the URL for where compareSpecificity was derived from.
  • Replace the comment where we import specificity with the fact that it is part of the internal API, not just that it's not defined in @types/csso. As part of the internal API, there is no contract with semver. It can break at any time, even with minor or patch updates, so I've pinned the dependency in package.json.
  • Moves docs to the types so code completion shows it.
  • Enable more of the regression tests that have been resolved.
