Hi, I am trying to insert Custom module into my page( since there no needed me option in templates). Once i put the code, save it and apply on the page, module doesn't look as supposed to and all page including the menu and footer just becomes a mess.
Please advise how to solve this issue.
Thanks.
Adding here link to the page, code and screen shot how it is supposed to look(if open just html in browser).
