Spinners
Loading spinners come in handy for everything from a page-loading animation to Ajax requests.
Basic example
Loading spinners use SVG and some simple CSS animations.
As such, the markup is very minimalist.
Use
.hiddenclass to hide any element when it doesn't need to be visible.
Styles
Use the contextual classes to change the spinner color.
.spinner-primary.spinner-info.spinner-success.spinner-warning.spinner-danger
