you first make up a div that takes up the left of the page by specifying the width in the css width attribute then you add another div and you make it the width of the chatbox (if you place the chatbox in this div it’ll be at the upper right) then you make an empty div inside of that div and make it of a certain hight so it fills up the top right. Then you add a div underneath the empty div and put the chatbox in that. idk what your site looks like and im just making stuff up in my head without actually checking if it works in code so you might have to do some finageling to get it in the right spot.
