Web Designing is what every one think of when they talk about Web sites - it's how the site looks: the colors, images and text that visitors see. There are many ways to design a Web site. If you know Web design and how to code in HTML, you can do it yourself. If you don't, you can:
Hire a Web designer/programmer to design one for you.
Buy a no-HTML-required Web site design software package to build your own.
Start with a Web site design template and make it your own with color, graphics and text.
