Default img src = null
Take a look at the following:
http://jsfiddle.net/N2Mtj/
Why does the default img src become null in the DOM when it needs to be shown?
jsfiddle.net/zmU9n/12/ shows this issue in the console. Locally I was able to trace the issue to something that changed between 0.7.1 and 0.7.2. Revert to 0.7.1 until we fix this. Thanks for reporting this. I'm surprised no one else ran into it.
I don't know if it's related, but it appears that if I try to use multiple prefixes in the setup, it ignores all the prefixes except for the last one specified.
It is. The issue only occurs when aliases (extra prefixes) are specified. Removing the aliases solves it. /13 and (better) /15 both work. The extra keys are throwing off the array containing the associated values.
Ah okay. I was trying to debug it but couldn't figure it out.
What exactly is the point of specifying multiple prefixes? If I'm simply using pixels as my breakpoints, I can use any prefix I want right? The really isn't a different between min-width- and r or some other random prefix is there?
Correct—you can use any prefix you want, and you only need one. The aliases were added in 0.3 to accomodate back-compat. with earlier versions. They add flexibility but are best to avoid when possible. Modes are autodetected since 0.3 by a private function called detectMode. The defaults like "min-width-" and "min-device-width-" are readable. Something non-descriptive like "r" is useful if experimenting between using "width" and "device-width".
