During his instructional video, the creator visits the CodeIgniter website at .
When he initially arrives at the site (at 1:32), it appears somewhat odd, almost as if it lacks CSS styling. However, after refreshing the page (1:37), it displays properly.
Does anyone understand the technical process behind this? My assumption is that JavaScript triggers the loading of CSS files. Can someone provide more insight or examples?
I am interested in implementing similar functionality on my own website.
