When the internet connection is slow and a web page takes time to load, why does it seem to load randomly?

HTML websites are read from top to bottom and as such the page should load the first elements on the page first but because some items take longer to download than others, an element on the page that comes first but larger in size can show up after a smaller element that is further down the page as it downloaded first.
