Is there a best practice for the right image size to use for a background image on a home screen?
I don’t think one size fits all. You should use CSS media queries based on screen size to determine which image you use.
This isn’t media queries, but it is on the subject of background images. Check the comments too:
Nic - do you have an email address? I have a proposal for you to consider.
Sorry, but I keep my email private. I’d be happy to hear you on Twitter.
Nic - no problem. I followed you on Twitter (troymcknight) follow me back and I will DM you the proposal.
