The image in this post is of a website which took approximately 30 seconds to render. It makes heavy use of CSS. As you can see, the developers didn’t consider what happens when their CSS loads slowly. The site is unusable – even confusing – until everything gets loaded and executed.
A good web experience requires a “progressing experience” – one where the user can get value very early and gets additional capability and options as more of the content is loaded. It’s bad design when the “content” is loaded but unusable because the “style” is slow. This type of experience suggests the developers and the owners believe “style over substance”. I doubt they want that to be their slogan.
