@flashman Select the object, type a class name in the class field (sidebar) ‘my-special-pad’ or whatever, It will create a class tag, now click this tag and the class editor opens, bottom of the main metrics options is the padding and margin. Select the areas you want to define and input values.
Now when you need that same style again on another element just enter ‘my-special-pad’ in the class field and those styling options will be added to the next object. Blocs uses classes as it’s much more powerful and means they can be used on multiple objects.
All the good customisation options come with classes. Just think of them as re-usable styles you need to give names too in order to identify them.
Stick with Blocs, it may be a little more fiddly in this respect but its actually teaching you the basics of web design by forcing class use. It’s extremely simple once you get the basic hang of it and it’s how front end devs build sites so it’s knowledge you can apply to coding sites if you move to that stage. Using Blocs as your spring board as many more advanced users do, then building the code out more in a code editor.
