Change the colour and thickness of hover. Also I want different hover colours for different elements.

You can change the state for an element in the style-manager and then change the color and all the other properties.

The editor will save then the properties associated to their state in css with all the #test:hover { ... } selectors.

@chapterjason - Thanks for the reply. but this didn't solve my problem. I don't want user to select element and change the states. I want to change the colours, thickness permanently for the whole editor. Means it doesn't depend on the user. I want to change it for the editor permanently.

@perfect-coders did you mean the style of the editor? Not the elements in the editor ?
