Other People's Responsive Design Stuff for WordPress

Plugins

The only sort of plugin solutions I'm aware of are thing like WP Mobile Edition that load a fully separate theme for mobile browsers.

Downside of this approach: They don't work for narrow desktop browsers.

Let's use an example: hpmor.com.

Here's a screenshot of hpmor.com in a desktop-width browser. It looks like a normal web page

What does this site look like on, say, an iPhone?

An screenshor of hpmor.com loaded in Safari on an iPhone 5, in portrait orientation. The careful styling of the desktop-width hpmor.com is completely replaced with styles from a boilerplate mobile theme.

Wow, that looks like an entirely different theme. Okay, how does it look in a just-as-narrow desktop browser?

While this site adapts to different devices, it's not reponsive. A truly responsive site would work at the same widths on any device.

hpmor.com uses a plugin called WP Mobile Editions, originally by CrowdFavorite. There are a lot of dead links when talking about the plugin, since CrowdFavorite appears to have ended support for the plugin after being bought. There's still a plugin under the same name, WP Mobile Edition in the WordPress.org Plugin Directory, which you're welcome to check out.

Remember the risks of serverside device detection:

Themes

There are _lots_ of responsive themes out there.

There isn't a way to sort the WordPress.org theme repository for themes that are specifically reponsive, sadly. Do soem searching and test themes to see whether they truly are. Responsiveness is not a required property for themes to be listed, but it is recommended.

Or, you can build your own.
