Recently I saw a wonderful video of the Code Queen about how te create a collapsing effect. But the funny thing is, it only works fully on mobile and not on desktop. When the text is uncollapsed (so before one clicks on the 'Read More' button) there's a big white gap between de button and the strip-image underneath (as you can see on the attached screenshot). However, on mobile it works fine (the uncollapsed and collapsed text). No white gap there.
I've tried all kinds of things, and asked around. I have no idea how to fix this. I really hope someone can help me with removing the white gap on the desktop version of my site: ZINGO POW!
Many thanks in advance!
