Background image ...
I changed just like in the tutorial :
functions.php
// wpMorphed Custom Background
add_theme_support( 'custom-background' );
and
style.css
/* wpMorphed Custom Background */
.content{ background-image:none !important; background-color: transparent !important; border-bottom:none; border-top:none;}
.content_botbg { background-image:none !important; background-color: transparent !important; border-bottom:none; border-top:none;}
It appears in the theme settings changes, just as I can change background ...
