Browser Compatibility of Pseudo Selectors

I've just finished two workshops - Create Tooltips with CSS and Create a Fullscreen Slider with CSS by David Conner. Can anyone tell me if the css used in the workshop is compatible in all browsers? or not?

I think most of the technologies used only supports up to IE9 and above. For chrome and firefox, it usually shouldn't be an issue.

Recommend you to check the code used in the course at http://caniuse.com/
