What is the purpose of adding a version in CSS?

Question

I´m using Gridless Boilerplate and this is how the main.css file is called in the header:

<link rel="stylesheet" href="assets/css/main.css?version=1" />

I'd like to know what the purpose of adding "?version1" is.

It's used to avoid caching issues. When you edit your css file you'll increment that version number and the browser will (presumably) fetch a new copy rather than using its cached version.

See Cache-Busting via params.

If that file changes over time, by appending that query string you force browsers that normally cache that file to get a fresh copy.
