it's certainly poor HTML.
Quote the
word "stylesheet" (mind lowercase not capitals!!!).
Properly end your HTML code, you're missing the /html closing tag.
Same with all other unquoted HTML properties.
And remember all properties MUST have a value, so no "<option selected>Hello" in a select box but "<option selected='selected'>Hello</option>".
HTML tags should be lowercase, uppercase html code went out the window years ago as a specification (I know some code generators haven't caught on yet).
Your link tag is never closed, this is poor form. Understandable for someone writing their homepage using an outdated HTML tutorial for professionals it should be a mortal sin.
I'd be very careful about using a parameter name "List" which is a
Java classname.
Use "list" instead if you must use something that's not descriptive.
