Try it in your private workshop first? And we don't instaban for accidents, we know there's a certain learning curve going on. Mainly we're looking to prevent hostile and malicious actions.
Also, I recommend using the Preview button to see what your posts look like on other devices. Sometimes copy/pasting can add a preset width to posts, which (although they look fine on your end) make them stretch the page on smaller screens. (Note: we know this is generally an accident so you won't get banned for that either! But repeatedly doing it long after someone tells you it's happening may result in warning points.)
If you do "break" something in your posts and aren't sure how to fix it, make a post in the Site Questions and Information section with a link to the post and we'll help you sort it out. (This includes private workshop threads because staff can see them; however, other users won't be able to even if you post a link.)
