No - there's a big prejudice in IT against web design; but in this case the "real" programmers are on pretty firm ground.
If you've done a lot of web design work you've probably done some JavaScript, so you can put that down under 'programming languages'; if you want to list HTML as well, then I agree with the answer that suggests "Technologies".
But unless you're targeting agents who're trying to tick boxes rather than find you a good job, a bare list of things you've used doesn't really look all that good. You're better off listing the projects you've worked on and detailing the technologies you used on each; that demonstrates that you've got real experience of using them rather than just that you know some buzzwords.
