What initiates the call for CSS?

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.

Answer №1

Cascading Style Sheets (CSS) can be triggered through two different methods.

  1. Automatically activated by the Document Object Model (DOM) during the parsing of the HTML file.
  2. Manually invoked using JavaScript functions.

In the video, the latter method is demonstrated.
