146 cybersecurity companies ranked by rating, review volume and listing quality.
Web design is the part of a website a visitor experiences directly: layout, typography, imagery, and how a page behaves on a phone as well as a desktop. It overlaps with web development and is often sold alongside it, but the skills are distinct — design decides what the thing should be, development makes it work.
Providers differ most in what they hand over. Some deliver a design system — components, states and rules a developer can build against — while others deliver flat mockups of a handful of pages. Ask what happens to the screens nobody drew: an error state, an empty list, a very long company name. Ask whether accessibility is part of the work or an afterthought, because retrofitting it is considerably more expensive than designing for it.
