CSS Required for Memberpress Styling

Description

Hi,
I have Memberpress but the account area and course area that the customer views is lacklustre.
I played around with CSS a little and the style and layout can be changed but i am not an expert on this. it should also be tablet and mobile friendly please.
I would like the Member & Course area to match my website theme, style and branding ideally.
For the person with the right skills, I would see this as a fairly quick and easy job because the styling is already there, it just needs to be applied to the Memberpress areas.
I have attached some screenshots of how it currently looks and what I am aiming to achieve.
I am sure you are more expert in this than I am and your help would be greatly appreciated.
Thank you. :)
