I am currently working on a project where I want to apply the same header and footer design from my homepage to all pages. However, I need a method that allows me to update the header and footer in one place, so that any changes I make will automatically reflect on all pages. I am utilizing CSS and JavaScript in my HTML pages for this task. You can view the main page here.
If you have any insights or suggestions regarding this issue, please let me know.
