There are some websites out there that are adopting 3D design rendering for that hero section either as a bold design motif or to show what they currently offer within their company. Various examples lend themselves to moving objects or static renditions.
The idea of hero images within the first view of the site has been around for a while. Web design illustrations have triumphed over standard hero images. These illustrations enhance user imagination and communicate ideas simply versus excessive digital visual stimulants. Illustrations allow the focus to be more on the written content and product offerings.
Color & Gradients
As digital screens become increasingly more powerful higher resolution screens offer better and cleaner renditions of color. We as designers or developers have seen many take advantage of the use of color. More and more sites are adopting heavy use of vibrant color as well as the use of clean gradients. For instance, big names like Apple and Spotify sometimes use gradients within there site.
