What does media="screen" mean in the below css code?
<style type="text/css" media="screen">
回答1:
The goal of the media attribute is to allow you to specify different styles for different methods of display.
Most commonly I use this to have 2 sets of styles, 1 for display (screen) and 1 for printing (print)
Normally on the "print" css I'll do things like hide buttons, strip out extraneous images, ads, etc etc. Basically, make it 8.5x11 friendly.

There are two types, screen is the default browser view. print is for print view.
