Add comments in the Sharepoint HTML Source Code

Question

I have a Sharepoint page where there is a lot of source code. In Access, SQL... I am able to insert comments to help describe the active code. Is there a way that I can insert comments in which will help to decipher the code on Sharepoint HTML Source. I tried entering <! -- --> and also trying Cntl+/ and nothing seems to work. I've also tried <%-- xxxx --%> in the code, but then it shows on my Sharepoint page.

Answer 1

Thank you - I entered the code to my Sharepoint page. The text "test content" and "===============" showed on my page and the "<!-- test comment-->" did not. That is what I was looking for. Unfortunately, when I went back into my HTML Source code the "<!-- test comment-->" was gone.
What I was hoping for is a way to enter a hidden comment that would stay with the code in which I could type in a comment that could describe the code. That way when others or myself are editing the code it may make it a little easier to read through the code.

Answer 2

You could add a script editor web part to the page and add the comment in the script editor web part.
