Thanks for everyone's suggestions... I have everything figured out.
It might just be me, but Composer is waaaay buggy. I basically just had to set up a basic svg, and did most everything else manually in the code.
Anyway, I set up a scrolling dock (12 icons) that can also be hidden. I put in a couple other small additions; it was a challenge for me (no formal html training) to get the animations just right, but it works great.
Anyway, thanks again to all for the help, I'll probably post the theme up for everyone in a bit.
