After following instruction, in Preview, my master page is showing up with message that no warnings or errors. However, my master page has no style and no images. I copied all the design files of images, css, js... All under one single folder onto the mapped drive where I also copy the master html file.
Prior to converting the html file to master file, I open the html file in a browser to make sure all my design files are copied onto the mapped drive correctly and it shows well. I don't know why in preview mode it's not working
thank you.
