Thanks friend 
Question though–
I would have to go through every page, every device, and fix every class from Width to %.
Thats a lot of work, which could be avoided given my explanation below.
A lot of the classes on the pages are NOT overflowing, on any devices, and they are set on Width-- not %.
Is it technically OK to keep the classes that are NOT overflowing on any devices…
keep it at Width… not change it to %?
Technically speaking.
I understand the principle is moving forward always use %.
Thank you,
Elliot
