Here I try to make 2 different webpages having 2 different widths pull an external CSS stylesheet as close to simultaneously as possible, based on their own widths. This is not a perfect world, but the javascript that reads window width brings them a little closer together.
On this page of the site you can watch the video online Javascript function displays window width and height with a duration of hours minute second in good quality, which was uploaded by the user Lisa Woodson 25 February 2016, share the link with friends and acquaintances, this video has already been watched 243 times on youtube and it was liked by 2 viewers. Enjoy your viewing!
