Thank you for the prompt response.
With regards to number 2) it was refering to the original post quoted here "When my web page window is not englarged, the containers in my website gets bunched up as in the picture shown below, is there any way to fix this? I would like it so that the sizing stays completely the same regardless of window size, and the side bar will either go to the bottom if there is no space, and they have to manually scroll right."
In addition, I would like to change the content width, and not the header width of the site. I would like to keep the header the same, while shrinking the content width.
I tried using this code, but it pushes everything to the left instead of adjusting both sides.
Please let me know if you can help!
