If anyone else is using the docs offline as I do. The style is broken, and renders the manual completely useless. Maybe on other versions, but definitely on 5.2.0f3. To fix you just have to navigate to the documentation path on your computer (“C:/Program Files/Unity/Editor/Data/Documentation/en/”), and then “StaticFilesManual/css”. Rename “css-manual” to “css”.
Works here on 5.2.1f1 on Windows. Would personally be surprised if this slipped through the 5.2 release, as we always do a manual validation of the offline manual before major releases, and this sounds like something that would have been found. Not least that online and offline are based on same files, so would believe this should have been the same issue in online docs.
Anyways, hope you can upgrade to later version and see if issue has been fixed for you.
