How to create in-context editing?
<p>My company is building a CMS. As a front-end web developer, I am asked to build a 'in-context editing' feature.</p>

<p>You can see an example here <a href="http://www.concrete5.org/documentation/general-topics/in-context-editing/" rel="nofollow">http://www.concrete5.org/documentation/general-topics/in-context-editing/</a></p>

<p>I want to know what kind of program should we know to build this? Can this be achieved with just JavaScript or some front end tools or does it need some server-side language?</p>

<p>Thanks.</p>
