Is it possible to have the Mailchimp CSS match the rest of my website?

Is it possible to have the Mailchimp CSS match the rest of my website? Currently looks like it’s using 100% width.

Can you help me with the article posts footer? Currently muddled up.

Could you also help me with header carousel to display what type of category post it is? Text with a solid background in the upper left hand side.

I’m also having difficulty making the header carousel displaying the latest post. It seems to skip the very most recent – which is odd.
