dom-style | Library to manipulate CSS properties

I have HTML like this:

I have a simple class called Draggable, which has a Moveable and a click event listener:

I am a beginner with using dojo toolkit and I am trying to create an alarm where the screen blinks red continuously when a button is pressed and only stop when the button is pressed again.

I'm in traineeship in a company and I need to used the program of another trainee who programmed it in 2012. So I have done some update but I have a problem :

In the report of this trainee the web page was a column on the left with a "menu" for request, at the bottom a field for the result of request, and on all the remaining space a map with different information. For the moment the problem it's the map in region 'center' it's like in region 'top'.

Header :

This will iterate through all required fields, highlight empty ones and remove highlighting from fields that have been filled in. It will set focus on the first empty field it finds. NB: Focus will be lost as soon as the view is left or a popup dialog is shown, so any "throw new PlatformRuntimeWarning('blah’);” statement directly following this new code should be removed.

fx.slideTo should do the job:
