How to make a button stay in its place independently of other elements?

Guys, I’m working on my Random Quote Machine and I need my new quote button to stay in its place independently of other elements (quote length, transition, etc.)

Can someone please point me to a resource or give me a light how to implement that?

Here’s my WIP: http://codepen.io/fellipedepaula/full/yJzYKX/

Thanks

One thing you can try is instead of giving your button class a fixed position, give it relative and position your text absolute inside it. Nice project.
