java - What is the easiest way to hide HTML code from users eye? -

-

i working jsp pages , know easiest way comment html/java code being able see when open source on web. now, used use 

<%-- html/java code --%>

however, later on screw highlighting of jsp file. maybe there way of commenting multiple lines without possibility see them in html source on web.

look: 

<%-- comment --%>  - commenting out html  <% /*java code*/ %>  - commenting out java code    <!-- comment --> - html comment, ignored browser
