I want to change the font color of my div on the click of a button using javascript. I have two buttons, 'Green and 'Red'.

<button type=button class=green>Green</button>

<button type=button class=red>Red</button>

This is my div

<div id=timer></div>

currently the font is red (default color), but once 'green' is clicked it will go green and when 'red' is clicked it will go back to red.

I know this is probably very simply but for some reason I can't get it to work :)

If you know how would be greatly appreciated.
