Styling the Main Block like the Module Block?

HI,
I try to Design the Main Block (Article/Blog) like the Module Block, but that doesn't work.
Here is an example First Image is what i entered in the CSS Edit Page and Second Image is what the output is.
As you see the Preview is different than the output. :blink:

Hi
have you clicked on Actions >> copy/apply changes ?
also check if you have a cache enabled, you must disable it and clear it to work

I tried all of this but it won't work. Is it even possible to design the Main Block (Article/Blog) like the Left Module Block?

not sure to understand, if you are talking about the modules, in your content you don't have any module here
articles and modules are displayed differently

Well what i mean is can i design the Articles (Content) like the Modules on the left side, with the Gradient and Border and Background?

you can style the content container, but not the content itself
here you have some articles, but you can have a page for a contact, a third party component like ecommerce, etc,
you can not style everything in template creator. If you need more styling, you can then use your own css rules and put them into the Parameters >> Custom CSS area
