After you upload the theme, it will look very basic. Nothing like my demo. Especially if you don’t have any content yet. It will look empty and just plain white. Don’t worry, it’s normal!
You will need to re-arrange the widgets and add stuff there. It won’t look instantly pretty like the demo. It requires some works. Install everything needed, add your blog title, create the navigation menu, and so on.
Follow all steps from the tutorial provided and you will get the same look like my demo.
