Just ignore the error. It should run fine in the browser.

The html tag and attribute names are case - insensitive. But the attribute values are not.

The IDE might be misnterpreting things.

It will work in the browser.

However I strongly advise you to use lowercase. It is much compressible than caps.

its always better to use lowercase, its not really matter in html ,W3C recommends lowercase in HTML , and demands lowercase tags in XHTML. so its god practice to use lowercase always.
