How to disable aui.css for custom pages in Liferay 7. Is it possible to do this somehow via portal-notmal.ftl
回答1:
aui.css is coming in through the unstyled theme, which typically is the basis for every theme there is. That being said, you can override it and remove it this way. It's refined in the styled theme, and also in the classic theme (in the same github repo, you'll find it).
If you do so, note that you'll still have to deal with a lot of formatting on your own - the classes and other DOM elements will be generated, but it looks like aui now includes the Lexicon CSS that you'll have to simulate if you get rid of it. Why you'd want to do so, instead of accepting the defaults and overriding what you don't like, is beyond me.
Edit, answering to your comment:
You'd simply create your own theme (Linking to 7.1 here, see below) with any overrides that you'd like to have. There's not a single file with an option, as this configuration file would be too complex and unmanageable.
Also, you sound like you've just started building your site - my recommendation would be to always go with the latest release and use 7.1 (at this time) and note that 7.2 is around the corner, Beta 3 has just been released
