Styling Dropdown cart

[behold]

Moved the dropdown cart block to the right of the page - and the little triangle at the top of the dropdown is now misaligned (I know not a top priority ) and would like to remove the little bugger if possible. Is this in a style sheet? See image below.

Hi.
Use browser inspector tool to check css file and rule to change

Wasn't familiar with the styling - but found it...
