This is a section that was generated by Moodle's HTML generator. I have started writing all the HTML myself because the generator seems to create some messy code that I don't fully understand.
I don't understand what you call "Moodle's HTML generator". Do you mean the HTML editor (such as the one we are using to write our messages on this forum?).
I agree with John Witts "That code looks like it could have been copied and pasted from Microsoft Word". Please note that you should never ever copy and paste text from Word into Moodle's HTML editor, as it will result in all kind of weird formating code to be pasted along with the text itself.
