I also cleared the preloaded styling in the header of an html file and when I tried to reopen that file it said that it couldn't open the html file because the property is null? I have searched the help sections for more details but it doesn't explain enough about how to link the different file type documents to work together in Google Web Designer. I like the way Google designed GWD but can I link the files I create with GWD inside of GWD? Was Google Web Designer made only to create the document files but we have to link them and test them somewhere else?
