A web designer's main job is to design web pages. There is a lot to consider in the design of websites which may not be immediately apparent when looking at a webpage for the first time. The aesthetic aspect is an important one and selecting the appropriate colours, font, layout and images creates the whole personality of the website.

In addition to considering aesthetic aspects, the usability of the website has to be a priority. It is important to create a page that the target market can relate to. For example, a website aimed at children must hold their attention and might use bright colours and an easy-to-read font with lots of images and not too much text, making it fun and attractive and easy to understand. The layout and structure must be easy to follow and most pages should not be too many clicks deep into the website in order to keep the information easy to access. Contrarily, a professional website aimed at doctors must convey a different kind of image but must still be easy to read and the information organized in a format that is easy to access.

The web designer is in control of the entire website and must understand how to create the appropriate image while ensuring the website is easy to use and information is easily accessible.
