Yes, as long as you don't use quotes. The only place we use quotes in HTML is in element attributes, never on content, unless intentional (for the reader to see).
HTML does not have a distinction between inline, single line, or multiple lines. The same syntax applies in all.
<p>This is some text <!-- inline comment --> that contains an
inline comment. Notice that extra space characters are ignored.</p>
<!-- this is a single line comment -->
When we have a block of text that
that we wish to include in the source
file, such as title, version, author and
attribution, we can write a nice orderly
multi-line comment to convey our message.
