Using https://github.com/eligrey/FileSaver.js it could be possible to have only HTML/CSS/JS based cms...also I found this one which looks like it can the do job ..http://dynalon.github.io/mdwiki/#!index.md
The languages you mention - HTML / CSS / Javascript are client languages; the reason most CMS's use PHP (or other) and some database is because they reside on the server which in turn modifies the page on the server, not the client. A client can't edit the server without server side code to interpret the request.
You could probably use Javascript, edit the page and store a copy locally, but only you'd see the changes; no one else.
