css touch of wordpress site

1. the padding top and bottom on the header should be reduce to 2-5px that will reduce the size of the header. header too large 2. the slider should extend full width on both desktop and mobile view 3. the padding bottom and top should be reduce to 2-5px that will reduce the size of the footer 4. the category scroll button on the side bar should be increased so that scrolling without mouse would be easy. now it very thin and small for scrolling making scrolling without mouse very difficult. 5.

Currently the header takes the mobile view header on desktop view of 14" screen size and below. the header should maintain the full main header across all desktop views. should only take the mobile view header on mobile view NOTE: my budget is $10
