Hello Tom,
http://www36.zippyshare.com/v/JFan9kE2/file.html
it has not been good to me,
the menu has doubled, I just want the menu below and the other when under the menu page does not follow the scroll
the image is 2120 x536 pixels, that measure must be to occupy the entire width of the page as in this web http://achievingsustainability.com/ also performed with generatepress
I have placed the CSS code in the CSS child theme
thanks Tom
