media-queries

问题 I'm trying to create a rule that includes/excludes based on both max-width and device-pixel-ratio. An example would be if I want the Kindle Fire @ 600px to be excluded, but the iPhone5 @640 (smaller real world screen) to be triggered. Does the following make an AND or an OR rule?

Here is the version of Modernizr I'm using... http://www.modernizr.com/download/#-backgroundsize-borderradius-boxshadow-iepp-respond-mq

问题 I'm just now diving into responsive CSS and design, and I'm wondering how I'm supposed to figure out various device widths out. I don't want to spend all day testing every single mobile device possible, I just want to get the responsive layout enough to where it works.

I'm not new to web development or
