Mobile matters. There are more than 4x the number mobile devices activated each day than there babies born and the question of how to effectively deliver your content to everyone, regardless of how they get there, should be the most important question for product owners and developers today. Enter responsive design.

Responsive design comes from the idea that there is not a mobile web and a desktop web but instead a single, unified web. The most obvious new design paradigm to come from this new thinking are websites that are not built on a fixed width grid but rather one that expands and contracts depending on how much screen real estate is available to the current user. To be able to do this, however, you want a powerful set of tools at your disposal in order to aid in you in the large amount of work needed to build a responsive design. Enter Sass+Compass

Sass 3.2 introduces a number of new features designed specifically to aid in responsive design including the ability to modularize your media queries and call them on-demand or to write media queries based on calculations in your Sass files. Compass v0.12 improves upon Compass's already impecable mixin and function libraries with a large update to Compass's Image Sprite functionality, a traditionally hard technique made drop-dead easy and essential to the Mobile First Responsive Design philosophy that should be taken when designing websites.

Compass also allows us to tap into all a community of extensions to make your lives easier, including some that are specifically designed to help us with responsive design, including Susy for fluid grids, Breakpoint and Respond-To to name and manage media queries, and RWD Kickstart to get you up and running from scratch with best practices quickly as quickly as possible.

Drupal 7 also provides us with some capability to greatly reduce the development costs for our mobile-first development, including some great projects including HTML5 Project for clean, semantic HTML5 markup, the Borealis Suite for semantic blocks and mobile-first responsive images, and Drupal 7's awesome new AJAX system to assist in lazy loading content, reducing download size and speed.

  • Anyone who suggests a website will run fast using responsive design would never get a job at my company. It's a great 'quick-fix' but not a usable solution unless you're talking about a blog or short article magazine. ;

    Mobile usability is far from web-page land. If you're thinking web pages, you don't understand how people use mobile. Web pages are really slow on mobile. Single page applications is the only approach people should use for mobile if they want people to use their website regularly.

    Responsive design is currently a good approach for making sure most of your audience sees the page best for their screen resolution on their pc or laptop (80%+ of the web browsing audience of most websites) aka 30' screens down to 10 inch netbooks.

  27. 27. A NOTE ON RESPONSIVE MEDIA Sass will not magically give you Responsive Media. Neither will Compass, Modernizr, any CSS or JS Framework, or even Drupal. For Responsive Media to be a reality, we need a new browser based standard. There are currently some proposed solutions for Images, and Apple is forging ahead with a non-standard solution in iOS6, but until then, everything is a hack. There are some tricks you can do in CSS to make media Fluid, however, and Sass rocks at this.Sunday, July 22, 12
