@ELiTE thanks for posting.
There was an issue that occurred yesterday in which dynamic items would lose their class names, but keep their styles. However, we’ve since pushed a fix for this issue.
We also sent out an update for class-less styling on March 14th–this will allow you to style an element without first giving it a class name. Doing so, however, will autogenerate a class name for you (e.g. div, div1, div 2, div 3, etc).
Styles that are colored orange indicate that the style is a default style, that it is inherited from a parent element, or inherited from a larger breakpoint.
Please let me know if this is helpful!
