In my theme, it is possible to add a button using a shortcode:
[button color="#COLOR_CODE" background="#COLOR_CODE" size="medium" src="PLACE_LINK_HERE"]ADD_BUTTON_CONTENT[/button]
When I enter this as a shortcode in some areas it does not work. How do I add the same thing as pure HTML to see if that works? Which file within the theme to I look at to work out the div class etc?
