Can I revision my templates, styles and components?
Yes. You should revision your Acquia Cohesion assets like other configuration using a service like Git.
Acquia Cohesion renames to Site Studio from version 6.2. Tell me more.
You don’t have to add units unless you want to use a specific unit or you’re adding Custom CSS properties.
Modifiers allow you to apply styles to an element when a specific class, id or attribute is present.
