Wt

I recently ran an HTML validity check and found some HTML/CSS errors which turned out to be caused by Wt:

I ran the test with one of my applications, but it can easily be reproduced with any application, like the Wt homepage: see https://validator.w3.org/nu/?doc=https%3A%2F%2Fwebtoolkit.eu. (The Wt homepage itself has some more issues, but those don't seem to be automatically generated HTML/CSS.)

• The first two errors are caused because Wt does not recognize <link> and <meta> as self closing tags in DomElement::isSelfClosingTag.
• The cursor: hand CSS error occurs on multiple occasions and is always preceded by cursor: pointer, and thus looks like the result of a failed find and replace operation to me.

I already fixed those errors and created a pull request for it: https://github.com/emweb/wt/pull/192. Although most browsers handle these errors pretty well, I think it is preferable to not have them in the first place.
