After I added the fullscreen sllder code from Foundation's Building Blocks, my captions wouldn't center and instead went to the bottom-left corner.  

I was able to get them to center by changing the padding in .orbit-caption to 19.75% when displaying as a desktop site. However, this doesn't remain centered when scaled to smaller screens.  

How do you get the captions to center when the screen scales responsively?  I tried various options, but don't know if it should be done using media queries, or with a different command on the .orbit-caption selector.

Thanks in advance for your help,

Steve
