writing HTML "comments" in page HTML code causing a space

When I add an HTML comment <!–Example Comment–> into the code section for a page, it automatically pushes down a line in the code. For example, if I do this: </div><!--Example Comment--> it ends up automatically doing this:

</div>
<!--Example Comment-->

The “HTML comment” doesn’t stay on the same line that I put it on (it bumps down to the next line). It then pushes my next line of code down and in turn adds a space.

Is there any way to stop this from happening?
