Logo Size and positioning

Hi Guys,
Im looking for CSS for the following:

– Alter size and positioning of logo. Ideally Id like the logo to appear to the left of the header text.

– I’d also like to remove the order summary billing address etc from completed orders and just include text indicating the order has been completed and can be tracked with the shipping tracking number.

– I’d like to be able to change the positioning of social icons and the space between social icons.

Finally I’d also like to be able include links to my page within the footer.

Thank you in advance!!
