A11y in pure CSS solutions based on `input:checked` pseudo selector

Question

I came across pure CSS solutions based on the pseudo selector input:checked, for example

• https://webdevtrick.com/css-sidebar-menu/
• https://webdevtrick.com/html5-css3-responsive-menu/
• https://webdevtrick.com/pure-css-tabs-responsive/

This solutions are very smooth and clever, the absence of JavaScript is good for performance but what about accessibility?
