Of the sloping type (6)

I believe the answer is:

italic

I'm a little stuck... Click here to teach me more about this clue!

'sloping type' is the definition.
(I've seen this before)

I cannot understand how the rest of the clue works.

(Other definitions for italic that I've seen before include "leaning over" , "Print style used for emphasis, titles of books, etc" , "Kind of typeface" , "Latin is" , "Printed in a sloping type" .)

I've seen this clue in the Evening Standard.
