Create a responsive navigation nav with no JS!

Start creating responsive layouts with confidence with my free responsive layouts course: https://courses.kevinpowell.co/conquering-responsive-layouts My very first video that I published here is one on creating a navigation. It worked, it looks good, and it's insanely popular (by far my most popular video). The problem is, it isn't responsive and is a bit old school in that it uses floats. ***** An important note, I've edited the CodePen a few times since publishing this. One is to not use `all: unset;` which Edge doesn't support. Another edit, which I talk more about lower in the description, was to make it tab-able ***** In this video, I take that same navigation but I update it to take advantage of modern CSS, making it fixed top, adding a semi-transparent background, creating the dropdown without any javascript, using flexbox and CSS grid to lay it out, and changing up the pseudo-element transitions to be higher performance. A commenter kindly pointed out that this isn't tabbable, which is an issue and causes accessibility issues. I've updated my CodePen to take this into account. Basically, I changed the 'display: none' on the input, which makes it almost useless, to instead have a position absolute on it and moved it way off screen. Then, I made it so when the input gains focus, the label gets highlighted to give us a visual clue as well. If you'd like to check it out, the codepen link is down below.
