Adaptive theme css which stylesheet to use? In the adaptive theme in the sass folder and it has following files, I understand about some stylesheets and for what purpose they are. But I am confuse about global.base.scss, global.style.scss, responsive.desktop.scss, responsive.custom.scss and print.scss. Now which one shall I use specific purpose. 

e.g. global.base.scss and global.style.scss, both has html and body now if we want to use font-size: 62.5% in root for using rem as unit so in which html shall I have to put?
The AdaptiveTheme site has a lot of great documentation to help explain this.

In general, you should use global.styles.scss to style elements that will look the same across all devices, and the individual responsive stylesheets (e.g. responsive.desktop.scss) for device-specific styles. If you want to override something in global.base.scss, you're probably best off doing it in global.styles.scss, depending on how fundamental the change is.
