Problems with Vs.NET and web pages

I am starting to use VS.NET for my web apps.

One of the .aspx pages I have opened gives me lots of errors in the editor, namely...

Code:

---

The active schema does not support the element 'link'.

---

I am linking to a stylesheet using the link tag, what is the correct way to link to a stylesheet in vs?

and

Code:

---

Could not find any attribute 'background' of element 'td'.

---

What it is telling me here is that background is not an attribute of the td element, which is obviously incorrect.

How do I fix these problems so these errors don't come up in VS?

Thanks

In your property grid, the Document object will have a targetSchema property. Change it to IE 5.
