Javascript

I need an event handler for the following html:























If the textarea in one of the sections is clicked then the corresponding hidden buttons become visible.
The butons stay visible if any other elments within the section is clickd such as images etc.

When the user moves to another section, the the old sections buttons become hidden and the new sections button become visible and so on..

I do not want to use the pattern of when a new section if focuses for the code to scan through all the other sections and hide the buttons. That would be easy and inefficinet.

I would like the code just to take into consideration the section that is being focused or blurred without having to use any other section.
