We recommend using the simplified HTML5 <!DOCTYPE html>
declaration on your Bootstrapped webpages. See also: Bootstrap's basic HTML template
Document is missing a DOCTYPE declaration
The (X)HTML document seems to not have any DOCTYPE
declaration; this can trigger quirks mode, which is not supported by Bootstrap and can cause the document to render strangely.
Document declares a non-HTML5 DOCTYPE
The (X)HTML document has a DOCTYPE
declaration, but it's not an HTML5 DOCTYPE
. This can potentially cause problems, especially if you're trying to use HTML5 features. Bootstrap's documentation assumes that you're using HTML5.
