CSS classes completion with CDN

Question

How to use the CSS classes auto completion on WebStorm for CSS files imported from CDN like this?

<link rel="stylesheet" href="https://netdna.bootstrapcdn.com/bootstrap/3.0.0-rc1/css/bootstrap.min.css">

Answer 1

Only files located under your project root are used for completion/navigation/error highlighting, WebStorm doesn't use online resourses for types resolving. So you have to download the css and reference it using the relative URL to make the completion work

Answer 2

This is not possible. Only local css files are auto-completed. Feel free to request this feature at their issue tracker: http://youtrack.jetbrains.com/issues
