Test Buttons
There is now a button in the editor to add a button. Just type in the button text, and the url you want to load when it is clicked.
There are also options for size:
Extra small will just wrap around however much text you put:
Extra Small
Small will have 300 pixel width
Medium will have 500 pixel width
Large will have 700 pixel width
Extra large will fill the page with (100% width)
