I was able to change the background colors of both the copyright notice and footer areas relatively easily. However, the background colors do not extend fully from left to right, leaving gaps on the sides and at the bottom as well. Could anyone advise on how to make the background colors span the full width of the page? Can we do it without using css?
Thank you and best regards,
Your 'footer' also has 100% of width. Just apply the background to it and remove the background from the nested containers.
You must understand how HTML is built and how to apply CSS to it, otherwise you cannot do simple things. I recommend going through a simple course, and you will enjoy your own creativity.
