    Yeah, you off course can do it for fun but as you said you are not much familiar with Javascript, doing this can have serious implications. There is simple code that can be used for doing so but you can’t actually edit the actual web page but you can edit the page as you see it on your screen.Here is the code:-

    javascript:document.body.contentEditable='true'; document.designMode='on'; void 0

    Thats really a good stuff. I have done this trick many times. All you need to do is visit the site you want to edit and let be load completely. Than simply copy and paste the code into the location bar of your web browser and hit the Enter button. Than start editing the webpage. Thats it.. Remember to not do this more often as it is dangerous tool used by scamsters to create fake screenshots.

    You can easily do it with a Firefox plug-in as well, that is Firebug. Firebug integrates with Firefox to put a wealth of development tools at your fingertips while you browse. You can edit, debug, and monitor CSS, HTML, and JavaScript live in any web page.Its CSS tabs tell you everything you need to know about the styles in your web pages, and if you don't like what it's telling you, you can make changes and see them take effect instantly.

    Download Firebug
