Do I have to use IMCE?
No. Site Studio allows the site builder to select, either use of IMCE or Entity browser for browsing and selecting images.
Acquia Cohesion renames to Site Studio from version 6.2. Tell me more.
Not yet. The Style builder does not have the option to add an animation name or key frames. This is planned functionality on our road map.
Custom styles are CSS styles for classes.
You don’t have to add units unless you want to use a specific unit or you’re adding Custom CSS properties.
