I'm trying to set up a template for a website, with a responsive top border with dropdowns in the navigation bar. I thought I had it all working at one time, but have gone back to previous files to no avail. The menu is responsive, and goes down into a hamburger icon, but clicking on the hamburger icon does nothing. I'm trying to do this without using too many external files.
The files I have are index.htm, a top border file, top.htm in the folder _borders, and 2 css files in a css folder: mystyles.css and topnav.css. This is the basic code from index.htm. I excluded site-identifying code and content. I've attached the other 3 files - didn't know how to paste them here separately. In the top.htm and index.htm I've commented out references to the mystyles.css file and it doesn't make any difference.
I'm using Brackets for this, and using Live Preview. If I just open the index file directly in Chrome or Firefox, there is no formatting, no nav bar or menu. But it looks just lovely in the Brackets Live Preview (other than the hamburger icon not responding. With my working website, I can open the index file in Chrome or Firefox and all is good.
If someone can provide some direction I'd really appreciate it!
