Hello dear friends …
I am was so exited when a couple of days ago I 've downloaded the try version of pinegrow … I felt in love with that BUT … I have to admit that I am too bad in coding … I can not even do the basic stuff …
For instance, I am not even able to change the background page of the sample “pinegrow.html” file 
The code seems easy BUT … Why I can not see the source of the background image? 
I don’t know … it makes me SAD … I wish I could cancel wordpress from my host but, it seems I am not even able to build a basic page. It is not as easy as it could appear … By the way, if You can help … I’ll really appreciate that! 
Many thanks.
Pietro
Wow … It is set in the CSS file … That’s why I didn’t found it in the html file …
