Responsive Design with WordPress (WCPHX)


Published on

I will go over some of the core content from my book, Responsive Design with WordPress, which teaches you how to leverage WordPress to get the most out of responsive design, implement best practices, automate important processes, and make your life easier overall.

  • Out Dec. 16.
    Presentation will be a teaser for the book.
  • Visit it on Desktop & Smartphone, and the same site will display 2 different ways.
    ***Just as much about big screens as small screens***
  • * Look at all of those devices (photo from
    * Projected by 2015, 50% of American Adults will using mobile as main source for Internet. It already is that in other place, like parts of Africa and India.
    * Mobile e-commerce traffic was over 50% and mobile was responsible for over 25% of purchases made on Thanksgiving in 2013.
    * Recently the Galaxy Gear was hacked to include a browser.
    BUT - RWD is more than Screen Resizing!
  • We want GOOD RWD.
    That means EM breakpoints. these adapt to the user’s settings, not just set pixel widths
    No arbitrary breakpoints based on device. then all you have is a website that looks good on 3 devices.
    75% of users abandon a website after 5 seconds. And not everyone has fast internet! (I know; I was just in the Philly airport)
  • * REsponsive Design + Server Side Programming.
    * Basically, do device detection on the sever end and display template files/section of code based on the results.
    * One note: You cannot test RESS driven elements by only resizing your browser. You will have to use a real device.
    * 2 plugins that can help: Mine & Jesse Friedman's
  • “Wireless Universal Resource FiLe”
    This API give you access to a full list of devices and features you can get by using built-in functions ex: screenwidth, wireless,
    There are open source, free, downloadable- but you need to update manually and they lag 2-3 months behind.
  • Monthly Subscription
    There is a free version with limited capabilities
    This is automatically updated for you.
  • built-in to WordPress
    Does user agent testing.
    I built a function that makes them work together.
  • Sidebar: Do error checking/catching.
  • **NOT different content…different layouts.
    Perfect example usage: navigation…will look at later
    In WP, we can even enqueue different scripts based on device.
    It’s important to remember NOT to change the content though!
  • Also, know your users!
    - From what class/type of devices do my users access the site?
    - Are my users there to see what’s on the home page, or do they usually go to a different page?
    - What information do I want to present as most important?- How tech-savvy are my users?
  • How do I do RWD?
    I’m not much of a photoshop guy, so I never really designed in photoshop.
    My tools: Paper, pencil, Code and the browser.
  • The mobile design bible, written by Luke Wroblewski
    Start with the smallest screen! This will allow you to determine what the most important content.
    Helps you avoid things like too many nav items, hiding content, and overloading the user
    Lots of stats and UX info (one thumb, one eyeball)
  • Don’t hide or change content for mobile devices.
  • You can’t capture the essence of a responsive site with photoshop.
    How do you choose what resolutions to mock up?
    Designing in the browser let’s you rapidly prototype, and see what you need to do in real time.
  • This is how you determine breakpoints
    Move your browser out until the content looks bad. When it does, that’s a breakpoint.
    Start with lowest common denominator.
    What about determining the site’s style?
  • talk about when to include JS (do I really need this?)
    Tools like image-optim for shrinking images
    tools like picturefill.js (we will look at)
  • Whole point of my book!
    Too much to cover all of the points, but I will mention some of the more fun stuff, and even include some never release code from the book!
  • * HnC is bad. Don't use that one.
    * With Jump to & Select Box I make use of RESS as to not load 2 different navs.
  • * Jump to technique with RESS
    * Why? Now we don’t have to show/hide elements with CSS, meaning that users will see all of the markup added.
    * Could do the same thing for Select box, but select will require custom walker (covered in my book!).
  • *Note about adding smooth scrolling with jQuery
  • Remember to style things nicely- especially the form! Make it easy for users to input date.
    As far as rendering… I propose 3 possible methods:
    -Incremental Loading (load only a few- requires JS)
    -Pagination (may require extra loading; must load page each time)
    -Separate page (I like this one)
  • Really tricky
    * WordPress creates multiple versions of image when uploaded.
    * You can even create more using add_image_size()
    * There are libraries that will display images based on width- like picturefill.js
  • One proposed method for responsive images is a <picture> element where you can select images to display based on screen width.
    This is a long way away, so Filament Group made this!
  • * We can use this technique with the multiple WordPress uploads.
    * There is a lot that goes into this portion so I won’t go over it here, but it’s explained thoroughly in the book
    * One Note- during research, I found that doing this for every image on the site on the fly…not very efficient (crazy, right)? At the moment, there is not a great way to do this- hopefully in the future.
    * To combat this, you could use a short code, however, this would render the media uploader/inserter useless.
  • * At the very least, using jQuery, we can remove the width and height that the WordPress editor adds in.
  • This is a problem still being solved.
    Aside from sizes there is retina issues, loading issues, and much more.
    It will likely continue until there is some sort of browser support.
  • * Multiple Devices
    * Multiple Connections
    * Browsers on devices
  • You MUST test on devices!! Don’t just rely on your computer’s browser
    That’s a lot of devices!
    Use discretion of course; what are your users using?
    Look for open devices labs, buy cheap devices, ask friends
    There are tools like browserstack to help as well (also, Edge Inspect)
  • Not everyone will have super fast Internet connections.
    Some people might even have…edge.
    (net neutrality joke)
  • Not to mention desktop browsers…FF, Chrome, Safari, Opera, and (dun dun dun) IE.
    IE: at least 9, 8 if your users need it. Remember: 9 doesn’t support media queries.

It’s about streamlining, semantics, great markup, responsive or fluid design, great typography, web fonts, content first, rapid prototyping and advanced javascript. My argument is that html, CSS and the browser tools we need have all advanced us past the point of needing Photoshop. - Josh Long ( ) 18
