Template Creator for Wodpress - Develompent course

WOOT! Work fine!

For all user: Dont forget to add this line in fonction.php file :
add_theme_support( 'custom-background' );

I have added this to display the options in the customize page

@car0l : I have released the 0.2.8 : Solved issue with '-' in the name, I have added a filter on the name field to remove all unwanted characters to avoid this situation

Tips:
Add this in CSS to make cover the background image:

body {
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
}

you can do that yourself in the "custom css" area
are you sure that the cover will always be used ?

No im not sure.
I added this code in your custom css area. It was just a suggestion. Maybe a option in the WP menu ?

I will check if I can add this as option directly for the background
