Ik krijg geen veranderingen doorgevoerd in child style.css

Goedendag,
ik heb problemen met de installatie van een css.
Ik heb twentyeleven gecopieeerd. Deze heet twentyeleven BGF
Voor dat copie heb ik een child theme directory gemaakt. Deze heet Twenty Eleven child
Echter, als ik veranderingen doorvoer in het css van dit childtheme, zie ik deze veranderingen niet als ik mn blog bekijk.
Miss kunnen jullie aan mijn child css zien wat er mis is:

/*
Theme Name: Twenty Eleven Child
Theme URI: http: //example.com/
Description: Child theme for the Twenty Eleven theme
Author: BGF
Author URI: http: //fietsenmakershoek.nl/
Template: twentyeleven BGF
Version: 0.1.0
