CSS rule to target specific admin page

How can you write a css rule that applies only to a specific page in wp-admin?
Like if it was a post or page you would use:
.page-id-12 a {font-size:1.2em;}

That that only targets one specific page where the id=12

How about a specific page in admin like the video tutorial plugin?
wp-admin/index.php?page=video-tuts

Can I write a similar rule that applies only to that page?
I suppose this will NOT work? .page-id-video-tuts a {font-size:1.2em;}
thanks!!
