FAB without JavaScript
I built a Material Design-style Floating Action Button (FAB) without using any JavaScript. This was achieved using only HTML and CSS, leveraging anchor links and the ":target" selector to control visibility and create the open/close functionality. Clicking the FAB opens a menu with links to different actions, and clicking a close button hides the menu. This approach does have the trade-off of adding entries to the browser history, but it's a pure HTML/CSS solution for a common UI element.
