Mobile Web Design – Working Code, Tips, Best Practices

Taking a web site to the small screen comes with a host of considerations: device width, available bandwidth, touch versus click interfaces, browsers with limited functionality, etc. At the same time, the simplicity of these mobile browsing environments lowers the barrier to entry for developers. Some basic HTML and CSS is all that is required to get started. In my research, I have learned a few things and decided to put the learning into action by creating a mobile web template available for anyone to download, remix, and reuse.

Read Me:

The above template is using HTML, CSS, Javascript, and PHP, but you could substitute any server side language for the programming logic. I also have it in my head that I can build an even simpler template with just HTML and CSS. I’ll keep people updated…

Here are some tips, best practices, and design conventions I learned along the way.

  • One column is a design convention worth following (See, or, or
  • Pick the essence or core pieces of your site to deliver to your mobile users. Think abridged version.
  • Follow the “m” URL conventions ( OR OR
  • Minify and optimize your CSS (See Clean CSS ).
  • Minify and optimize your javascript (see JSLint).
  • Plan for low bandwidth – Keep images close to 1KB or under.
  • Test on multiple mobile browsers and emulators.
  • Don’t plan on javascript being available – the above template still works when it’s turned off.
  • Build your app so that it loads only necessary data when requested (Use Ajax or Server-Side includes).

I’m interested in any feedback or questions so please share in the comments. I’ve also created a more robust mobile application example for TERRA: The Nature of Our World available at If anyone is interested, I’m happy to share some of that code as well.

Advertisements API and YouTube API Code Samples – Library Mashups

My chapter “ and Digital Video Collections in the Library” for the recently released Library Mashups edited by Nicole Engard was in need of some code samples. I wanted to show how to use the APIs I kept mentioning in the writing which focused on the digital library mashup of TERRApod. So… here they are in their basic, rudimentary glory.

The complete code is available for download from my code archive. Think of these examples as the raw materials for building mashups with the API and YouTube API. The example relies on PHP 5, but I made the YouTube PHP4 compatible and you could adapt the code from there for the API. I also included some CURL code in the comments of the files just in case your host requires it. If you have questions or improvements, drop a comment.

A quick word about the book: If you are at all interested in mashups and web services, take a closer look. The book covers one profession’s (the librarian) application of web services to library data problems. Contributions from industry leader’s like John Blyberg, Ross Singer and Karen Coombs make this an interesting read for anyone interested in how web services and open data are changing the nature of web development for libraries.
