Widgets, Fonts,

Hello, Please help me with the following issues: 1. How to change Head Fonts Size & Text Color (red) in a specific Widget where I have placed a shopping Cart. 2. How to change the background color on that particular Widget from orange to white, while keeping its borders orange. 3. Fonts are showing too large on the head texts of the Dishes. How can I correct that. 4. A gray horizontal line is showing up dividing Dishes in the wrong places. How can I remove them or place them where I need to? Here is a Link to the page. http://bloomrestaurant.com/takeout-menu/ Thank you so much
