I've seen this on a site:
<link rel="stylesheet" href="http://blablas.com/built/assets-styles.css?v=12355" />
which need to be underlined assets-styles.css?v=12355"
How to compile css file as above?
is it possible with less or sass?
[update]
And How about this?
<link rel="stylesheet" href="https://blablas.com/built/assets-201501-35b4b2bf0e75bb40f98d111b2d97951d.css">
