I have a persistent issue with my menu increasing padding on reload, creating an annoying flash on my homepage stefaanoyen.be.
This is a gif of the reload:
It seems like the padding on the menu increases when the text is loaded. The same effect can be observed with the red button lower on the page (padding increasing to the right) and with the white area this button is in (padding increasing below).
Whatever I try, this issue persists. Can you guys help me out? Thank you so much in advance!
I would try to preload font that you are using.
