To do: buttons with hyperlinks

[EstherDeLoof]

Would it be possible to create an object (e.g. block of text or image of button) that can easily be located somewhere on the slide? In that way, I could easily add additional links to the slides.

The reason the Twitter button wasn't displaying as expected, was a missing script.

I added a button example, which might or might not be what you're looking for.

Perfect! And I'll be able to add a background image to the button here I guess:
background-image: linear-gradient(to bottom, #3498db, #2980b9);

That's right indeed!
