When the internet connection is slow and a web page takes time to load, why does it seem to load randomly?
In: Technology
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.
Previous comment is basically true, but the randomness can also occur because:
– top code, rendered first, can be an element that displays at the bottom of the page, or anywhere the coder decides it to be.
– webpages these days are full of content outsourced from, usually, more than a dozen of servers. FB scripts, Google scripts, ads, images, specific scripts – each from different server, and their bandwidth or processing speed vary very much.
There more reasons, but those are main ones in my opinion.
Different elements like images can have different sizes, and be even sent from different servers. They will arrive and show up at different times. With fast internet you’d probably not notice There’s more to it, but that’s the first.
