Properly proved. Has structure, has flavour, has a point.
Summary
A developer shares a code exploration project implementing a menu reveal animation using only HTML and CSS with clip-path techniques. The project demonstrates a circle that grows from the top-left to bottom-right corner to reveal a menu, using vmax units and mathematical calculations (multiplying by 1.42, which is the square root of 2). The work is inspired by another developer's implementation and focuses on pure CSS solutions without JavaScript.
Key quotes
· 4 pulledIn this example, I'm trying to implement a menu that is revealed when the user clicks on a button. With HTML+CSS only. No JS.
The menu is revealed by a circle that grows from the top-left corner of the screen to the bottom-right corner.
A fun clip-path calculation that I used here (clip-path: circle(calc(1.42 * 100vmax) at 0 0);) is based on the vmax, which is the larger of the viewport width or height.
Then multiplied it by 1.42, because 1.42 is the square root of 2.
