Automatically add a ?v=0.X version number to css link

As you know, to invalidate css browser cache when we push a modified css file, one way to do it is to change the link to the css file by adding at the end a variable with a value that we increment each time we make a modification to the file. That way when we push our files to the server, the updated css file is automatically downloaded by the client and we are happy because existing visitors have the updated version.

It would be great to have such an option : automatically increment a version variable in the link of the css file whose content has been modified every time we save the .html file.

Or maybe I’m too lazy, I should just do it manually ?
