d.wowBook.defaults={width:1200,......YES
d.wowBook.defaults={"width:100%",......NO
d.wowBook.defaults={'width:100%',......NO
d.wowBook.defaults={width:"100%",......NO
d.wowBook.defaults={width:100+"%",......NO

Answer 1

You can provide width in percentage by using jquery

$(document).ready(function(){
 $("#book").width('40%');
//or
 $("#book").css('width','40%');
});
