Wed Design is all about how you build, design and test a web site that you have created. Web Design involves:
In Web Design you will have to first make a site plan. Which just means that you have to skech out what you want your pages to look like. The graphic design is when you make a exact copy of what you skeched on the computer to see what your design will actually look like on the internet.
Data design is when you plan out what you want to be on your website like what kind of info you want to put on the website. Programming is when you actually sart to make your website by writing codes to make your awesome website. Testing is when you finish writing the codes and check your website to see how it looks and if the links are working. If you find any mistakes you can just go back and correct them.
I found this video on the school website that shows how you can design your website on dreamweaver.
