There is a page that displays about 40-50 block elements with append (), which makes the page very large. Items are displayed in 3 pieces in a row. I want to make sure that when the page is loaded, only the first 9 elements are displayed, and the rest start to appear when scrolling down or by clicking on the "Show more" button. Tell me, please, what script can be used for this. Searches did not give anything.
