The design of a web page or website refers to its unique visual and auditory aspects. It is an essential element of a brand’s or company’s visual identity and is generally designed to be permanent. However, it can be temporarily modified to adapt to specific events such as special dates, celebrations, sponsorships, or product launches, for communication purposes. Some e-commerce sites even offer all or part of their design for sale as part of their online advertising packages.

The elements that make up the design can range from a simple background to a complete redesign of the page, in order to harmonize it with the advertiser’s visual identity. This visual adaptation can also extend to other media such as newsletters, press materials, or storefronts.
