Your designer is able to adjust the fonts, color and styles of your Header and Footer. They can also add in your logo and change the existing sections of your Header and Footer to better match your brand (for example: changing what the shipping promotion says). We do not alter the layout or functionality of the Header, Footer, Navigation, or Internal Pages (for example: category or product page). Your new fonts and styles, however, will transfer across these pages of your site, creating a consistent branded style.
You can always navigate the theme’s demo to get a good idea on its functionality and layout; each can be found here
