The term “web development” is relatively broad in its application. You could create a single website page from a Wix template, or you could painstakingly develop a massive website with thousands of original pages — and technically, both of those would count as web development.
When you build a website, it’s a bit like designing a house. On the one hand, you want to look at painting the walls, installing the countertops, and laying the carpet. But beneath all that, you also need to lay out all the pipes and wires that enable your utilities to function.
