The above code did not change position on screen.
The code below works for me to a certain width
max-width: 800px !important;
max-width: 200px !important;
The primary content will change to a certain point around 800px. If I set it to 300 it is small. Set it to 500 it gets bigger. Anything after around 800 it stays the same. I can change 800px to 1000px it does not get bigger.
Thanks for all your hard work.
