@jmossey That’s right. But if you want, for example 
, different coloured buttons, you can make these buttons in Illustrator, Photoshop or Sketch etc. Import these as pictures in a container, attach a link and create hovers. It’s a workaround, but so you can do more. If you want a button for fun in each corner, you can save the buttons with a white background.
I don’t think it’s possible to alter the CSS like you can alter code in Velo. That would be a great option to have.
