How to correctly use marhup code in forum

I would like to please ask for a (sticky/blog) post on how to use the HTML tags and attributes below.

 

Hi, Seems a lot of people have problems with this. But I never. Strange.

A hint, don’t use HTML tags in the visual tags, just use the button above the editor. If you want to use THML tags clearly, click the “text” tab in the top-left corner.
