<p dir="auto">While VS Code uses the same css.plist for CSS syntax highlighting as TextMate, Atom has this own forked version that is way more up to date:<br>

<p dir="auto">Would be nice to find a way to keep all three in sync.</p>
<p dir="auto">Not all parts of css.plist are used in VSCode. For example some features such as the Media Query media features are highlighted from css.plist, but CSS properties that are not included in the file such as the flex box properties get highlighted anyway. I’m not 100% sure which ones need to always be up to date, and which ones don't matter for VSCode yet.</p>
