TIL about using "vw" and "vh" (viewport width and height percentage) as measurements in css, which allows me to make proportional circle buttons that adapt to the screen size
god bless css3
@squirrel I'm gonna be honest I don't understand heads or tails about this stuff but I love when people talk about it.
explanation, if you want
@ratbaby viewport is whatever size window/display the page is being rendered in
being able to use either width or height as a proportional measurement in any styling opens up possibilities such as constraining a circle to be the same height and width, relative to the window width
before those units, you could only use % which is a percentage of that measurement alone, so width could be proportional to width and height could be proportional to height only
@squirrel ooo I've learned things! :D
