Modal Window Customization

Hello there!

I am interested in customizing the modal window in a number of ways, and was just looking for some assistance if possible!

1. This is relatively simply – I’m hoping to use the the “light” (second-light) button color style for a modal button, and I’m having trouble figuring out the CSS for it – is there someway to just replace the default style or even just replace it in on instance?

2. I’m using this modal window for an email signup, and I’d like it to be included as a component of my menu as well. Is there anyway to link the modal window to a menu button?

Thanks for your assistance as always!
