Hmm… I kind of solved it on my own. I looked in the options menu in WP, and under Read, I changed the number of posts shown per page to 1 instead of 10. It works like I wan’t it to on the main page, sort of. But the problem now is that I would like to show more than one post on the blog itself! (The grass is always greener on the other side! XD) Also, it poses some issues with having differing lengths on the posts shown on the main site, since it either causes empty space below, or overlaps the border again. Maybe changing the height to auto? I’ll try!
