When I create the child style.css file and add some code to test it (Like changing the title color, change the font-style) nothing happens. It seems that my blog is not acknowledging the new style.css. Yet, I was able to activate the child theme inside of WordPress.
This is what my style.css looks like:
Theme Name: Blog Name Theme
Theme URI: http://website.com/
Description: Child theme for the Twenty Twelve
Author URI: http://website.com/
