Web design and development is an umbrella term that describes the process of creating a website. Like the name suggests, it involves two major skill sets: web design and web development. Web design determines the look and feel of a website, while web development determines how it functions.

Because there isn’t always a hard line that separates the two roles, the titles are often used interchangeably. As the web continues to evolve, so do the roles.

In the almost 30 years since the first website was created, numerous job titles have emerged to describe various skill sets used to create a website, with more coming out every year. These titles often overlap, and their meanings change from company to company. It’s enough to make your head spin.
