Sticky position suddently doesn't work

[Aezer]

Hey guys,

I’m running into a trouble where I designed a 2 column page where one column sticks to the screen while the other one scrolls through, nothing complicated and it worked until now. My position sticky doesn’t work anymore. I tried to check if I had made a mistake with the overflow property, but no. It works in preview by the way.

Another good thing to know about position sticky. If any parent element has overflow:hidden it will break position sticky. This is a known issue with CSS.

Yeah I know, that is why I said in my original post that I already checked for that type of error, but thanks for reminding it
