 This means you can create a function wich handles only the coloring side of your button, and if your button also needs some logic you just create your own unique function for that and add it to your button.
 
 With this knowledge we create now a function where we pass a button-object as parameter and this will setup the coloring of our button:
 
 **Example snippet:**
-````lua
+```lua
 local basalt = dofile("basalt.lua")
 local mainFrame = basalt.createFrame("mainFrame"):show()
 local button = mainFrame:addButton("firstButton"):setPosition(3,3):setSize(12,3):setText("Click me"):setBackground(colors.gray):setForeground(colors.black):show()
