If I want to make a background, it tells me to make a CSS in order to do it. I looked it up, and understand how, but what I don’t understand is exactly how do I do it if it’s not even my site? How would I even get the code?
For example, here’s someone explaining how to do the background things, but how does he get the website to connect to CSS?
Moreover, how is this possible with someone else’s website?
Hope this explains things better….
