# Learn multi-thing development  image source: [http://bradfrost.com/blog/post/this-is-the-web/](http://bradfrost.com/blog/post/this-is-the-web/) A site or application can run on a wide range of computers, laptops, tablets and phones, as well as a handful of other things (watches, thermostats, fridges etc...). How you determine what things you'll support and how you will develop to support those things is called a multi-thing development strategy. Below, I list the most common multi-thing development strategies. - Build a [responsive (RWD)](https://en.wikipedia.org/wiki/Responsive_web_design) web site/app for all things. - Build a [RESS (responsive web design with server-side components)](http://www.lukew.com/ff/entry.asp?1392) web site/app for all things. - Build an [adaptive/progressively](https://en.wikipedia.org/wiki/Adaptive_web_design) enhanced web site/app for all things. - Build a website, web app, native app, or hybrid-native app for each individual thing or a grouping of things. - Attempt to retrofit something you have already built using bits and parts from strategies 1, 2 or 3. This could be as simple as sprinkling in some screen-size agnostic UI parts or attempting to fully support other things with the entire UI. ##### General Learning: - [Adaptive Web Design](http://adaptivewebdesign.info/) [read][$] - [Designing with progressive enhancement](https://www.filamentgroup.com/dwpe/) [read][$] - [Responsive Typography](#) [watch][$] - [Responsive Web Design](https://frontendmasters.com/courses/responsive-web-design/) [watch][$] - [Responsive HTML Email Design](https://frontendmasters.com/courses/responsive-email/) [watch][$] - [Designing Multi-Device Experiences: An Ecosystem Approach to User Experiences across Devices](http://www.amazon.com/Designing-Multi-Device-Experiences-Ecosystem-Approach/dp/1449340385/ref=pd_sim_14_8) [read][$] - [Responsive Web Design Fundamentals](https://www.udacity.com/courses/web-development) [watch] - [Responsive Images](https://www.udacity.com/course/responsive-images--ud882) [watch] - [Mobile Web Development](https://www.udacity.com/course/mobile-web-development--cs256) [watch]
