Hi I am new to Wordpress development and I have learned a lot already but I do not understand why the text and content in the pages and posts does not keep the format that the user sets in the back-end editor for posts or pages. And everything looks like a mess, formatting goes wild and it does not resemble the editor version at all. What am I missing in my code? I don't understand what is wrong, is it my css rules?
A funny thing is that when I change to another theme, the formatting does remain in place. And it seems to work with any theme available in the wordpress themes section.
