HTML
CSS
Javascript

a server side language (PHP, Ruby, C# for ASP.NET)
PHP is the most common and probably the best for beginners.

You should also be familiar with the following software too.

Photoshop
Illustrator
A decent Text Editor (Sublime, Textmate)

There are some great tutorials online to follow. Here is a list of websites you should be following daily.

Smashing Magazine (a blog about web design and development and best practices)
Http://smashingmagazine.com

Tutsplus (A blog with tutorials on Photoshop, Illustrator and web development)
Http://tutsplus.com

Shay Howe – Learn Web Design (A tutorial site on Web Design HTML and CSS best practices)

I would also like to recommend a book called ‘Above the Fold’. If you can get your hands on this book this will go over the surface of web design. It explains all the areas of Web Design and will give you a good grasp on what it really takes to build a well branded website that meets the needs of the clients.

As for how much a web designer can make it really varies. I started out at 20 an hour and now I make anywhere from 30-40. I am still learning myself as I am not at the elite level in my area.

I also want to add something. If it seems that there are no jobs or you are having troubles finding jobs, then you will have to create the jobs you work at. A lot of companies don’t even have an online presence yet and it will be your job to find them and help them take their business to the next level online.

The courses are related to :-

PHP/SQl ,
Java,
.Net,
CSS(cascading style sheet),
HTML,
HTML5 etc

To get the admission the following requirement are need.

A working knowledge of HTML and CSS hand coding to W3C standards. Complete this self test to determine whether you need to complete this pre-course. Include your score in your application statement.

If your score was below 70%, we recommend the standalone course, Foundations of Web Design & Development (formerly Introduction to Web Publishing). You may begin this online course at any time and complete it within 3 months of your date of registration. You must complete this Foundations course before the first class in this Certificate program.

A working knowledge of
using a current Windows or Mac operating system
word processing and office productivity tools
standard Internet communication tools, e.g., SFTP and email.

Computer graphics fundamentals and familiarity with a basic image editing or paint program desirable.

Completion of at least two years of college preferred.

For example, some of the most common types of code used to create websites are HTML, XHTML, ASP, PHP, JavaScript, Flash, XML, and ColdFusion. Now, don’t let that deter you from wanting to learn. Not every web designer knows all of these languages, and it isnt necessary either.

Each type of language has its own method’s for doing things. HTML is the most basic. You can use this alone to create a website. However, advanced features (pull down menus, forms, etc.) require knowledge beyond basic HTML. Does your school offer this in this class?

Secondly, web design also requires graphics. There are places you can go and pay someone to make them for you, or you can learn them yourself. Granted, they are not a necessity, but make web-pages more aesthetically pleasing.
