I have a page that is entirely covered by strips from the top of the page down to the footer. The top-most strip is at y = 0, that's the very top of the page. The top of every strip after that one touches the bottom of the previous strip. The bottom of the last strip touches the top of the page footer.
On some strips, there is a textbox with a click event that expands the strip below it if it is collapsed, and collapses it otherwise. Those collapsable/expandable strips start out collapsed and there is a huge gap at the bottom of the page. Endless scrolling to get through it. Obviously, the page height is not adjusting accordingly, which it should according to this article from Wix:
Here's a quote from it:
"When elements collapse, expand, and grow, the rules governing the footer are identical to those discussed above. In other words, if the gap between the last element on the page and the footer is within 70 pixels, collapsing the last element causes the footer to move up and the page size to shrink."
Get that last part? The page size is supposed to shrink. So why is it that on the page I described above, on which there are zero pixels between one strip and the other (way under 70), I'm not observing the behavior described in the article?
