I created a website http://getting-grants.com I believe host has embedded information at the end. When I validate the website, errors are listed at the end of the page. How can this be addressed? Thanks.
I suspect the only solution is to find a new host that doesn't do that.
You should use a complete doctype (one that includes a URL) to get browsers to render as close to the same as possible. I recommend HTML 4.01 Strict. A doctype is not a magic fix. It is the first step in the process of fixing your page.
