  • A Brief Note on Responsive Design and Constraints

    (In response to Adam Silver’s Stop using device breakpoints)

    There are two points that I like to add –

    The relationship between Constraints, Content, and Context

    Content

    Content will always affect Constraints (i.e. breakpoints) and vice versa.

    What I do is a) use the familiar set of breakpoints as initial guesses and b) treat them as assumptions that need to be tested and verified.

    If you’re getting more breakpoints, maybe you need to reconsider your initial ones. Some may just need to be:

    1. Moved or
    2. Removed completely

    Experience

    This is probably more a developer than designer problem(?) but depends on your background. It comes down to hands-on knowledge of various devices.

    1. Don’t assume the device you have on hand is the one [definite] solutions. Just because you have an iPhone doesn’t mean everyone else does…sounds sensible but you’ll be surprised how many people don’t follow that advice. I have experience because most of my work involved non-American clients (more likely to see a Samsung than an iPhone).
    2. Comes back to testing on multiple devices – using BrowserStack (or other simulators) helps testing for both iOS/Android devices or just get a few old/borrowed devices on hand.

    The idea here is to get use to the idea of breakpoints as initial guides, not fixed points.

  • Future Imperfect

    As I’m writing this, it’s a rainy morning in Vancouver, Canada. Nothing new. Spending time with friends that I don’t see but once a year near my birthday. In this case, I’m here to attend the IA Summit conference this week. This is my first non-US conference since IxDA Interaction 13 in Toronto.

    Looking back at that conference there were a number of things that stood out. A number of them became influential years later. One of them was a short lecture by a designer named Nate Archer called “Beyond Responsive”.

    Nate Archer: Beyond Responsive from Interaction Design Association on Vimeo.

    Well, four years later, those words seem prescient right now. The world has been filled with all sorts of devices that we access the web. More than just the trio of phone/tablet/desktop. Basically, any device that has access to the web is an access point – from watches to 4000K TVs. But there is another way of looking at this. Instead of “devices”, let us consider going in the direction of “inputs”. Responsive design appeared not just with mobile devices but devices which are also touch-enabled. Now, mobile devices are as ubiquitous as any household device, front-end developers like myself have to deal with coding for interactions that take place on touchpad as much (or even more) than mouse/keyboard. (Though we could be doing a better job at the keyboard then we are currently doing.)

    [Note: touch-enabled devices are not necessary phones/tables and doing feature support for touch is still a bit tricky]

    In some respects, the beautiful lie of responsive design is that the constraints are visual, via breakpoints and media queries? But what if those constraints aren’t visual. CSS has hidden artifacts describing inputs – media types. If one would look at the specs (https://www.w3.org/TR/CSS21/media.html#media-types), the following types are supported:

    screen, print, speech/aural, handheld, tty, etc.

    Screen is the most familiar with print/speech following. But there’s tty? From the spec, tty refers to devices like terminals and teletypes. The later was a telecommunication device that has long since disappeared with the advent of email. But back in the day, it was considered important enough to be considered in the W3C CSS spec. Now think about the future. Someday, will we may consider mouse/keyboard interactions as obsolete as teletype?

    Now, we are seeing the advent of AI interfaces – sophisticated interfaces that allow access to the same information like we do with mouse/keyboard and touch.

    Which comes back to the conference I’m attending, IA Summit. This year’s topic is artificial intelligence and information architecture. The main job of a front-end developer is building interfaces for acquiring information. Obviously, things will change in the next couple of years. But change into what?

    Over the past few years, many of you have heard of the term responsive design. Basically, it’s an approach where we build web apps and websites to be usable across a wide range of devices, from mobile phones to laptops.

    But instead of tricks, techniques, and more code (there are plenty of basic responsive design tutorial out there), I want to go in a different direction. Instead of asking ’how do we do this?’, I want to ask ’why do we do this?’.

    Here at Innate, we recently designed our Accessibility Services website with responsive principles. Instead of answering basic questions, we want to delve into the types of problems we encountered that influenced how the design developed, as these are common problems for all responsive sites. It doesn’t matter if it was one person or a company like Innate; when we all build a responsive site, we are solving these problems at every step of the way.

    So, let’s start solving some of these problems.

    The Three ’C’s

    Responsive design is like solving a puzzle. When someone asks me to describe it, I tell them the following three words: constraints, context, and content.

    For brevity, I like to call them the three ’C’s. If I were to give them descriptions:

    • Constraints –the conditions, restrictions, and parameters for the given problem
    • Context – the situations or circumstances in which you have to work on the problem
    • Content – the way in which information is displayed for the given problem

    These three ‘C’s are needed in varying amounts when building a responsive site – sometimes, some more than others. But together these are necessary to solve responsive problems. The better the mix of each piece, the better the product. Each part contributes to the whole product.

    So, how do we use the three ‘C’s?

    Graphic representation of Content, Constraint, and Context

    Referring to the above graphic, think of Content as water. Constraints as a container. Depending on the amount of content, you will choose the appropriate constraints to display this content. If you have a long article, the viewing on a phone will require more scrolling than that of a wide screen monitor.

    With Context, referring back to the water analogy, our problem can change depending on circumstances or environment. At room temperature, water is liquid. But change the temperature and we get either ice or steam. With design, that means adjusting our design to meet these changes.

    Constraints

    Like all problems, we need constraints to get the best solutions and designs. Finding constraints allow us to make good assumptions about how to solve a problem. Let’s start by making a few right now.

    The most obvious problem in responsive design is conforming to the screen sizes of numerous devices. How do we get a website or app to fit in the screen width of a phone, tablet, and laptop? When we consider the number of devices on the market, we see there is a large range of screen sizes. But by finding constraints, you narrow down the problem, making it manageable.

    What is our minimum screen size? Right now we’re not thinking about smart watches (at least not for the purpose of this demonstration), so let’s stop at mobile phones. Apple has pretty consistent design parameters and the classic iPhone has a minimum of 320 px, which is under the range of recent larger models. This is the stopping point on the small end of our constraints scale.

    On the large end, we are not considering TVs (at least not for the purpose of this demonstration), so we need an upper bounds for desktop monitors or laptops. Right now, 1400 px is a nice place to put an upper-limit constraint.

    Why these numbers? Global stats are a start but the best statistics are a combination of site logs and Google Analytics.

    In addition to the extremes, we have a few other number to consider, such as ones for laptops (1024 px) and iPads (786 px). These aren’t necessarily standard, but they are starting points. During the course of building, you will find out the other two parameters – context and content – will affect the constraints. For example, the footer may not look right somewhere between 320 px and 768 px; if this is the case, a new constraint will need to be added. You can really have as many constraints as you want, but the best motto (and the one with less headaches) is the fewer constraints, the better.

    Constraints are like conditions, though. They don’t need to be screen size; there are others as well, such as orientations (vertical or horizontal), resolution and pixel density, etc. Other constraints could come from areas beyond your own work (product requirements, project specifications, etc.).

    No matter which constraints you are dealing with, they can be influenced by context and content. Let’s look at how this works.

    Learn how to adapt to different screen sizes from this informative Intel tutorial:

    Context

    As you’ve seen, constraints can help define a problem and lead to a solution, but context informs these constraints. Oxford Dictionary defines ‘content’ as:

    The circumstances that form the setting for an event, statement, or idea, and in terms of which it can be fully understood and assessed.

    For example, taking one device (a tablet), we can drill down in the Analytics data to discover Insights that drive content in learning lessons such as : 1) when users read tablets depends on the time of day at home or work, 2) tablet users are using their device in landscape instead of portrait mode or 3) whether the devices used for certain tasks are Android or Apple, and screen size/viewport.

    But more than just statistics, it comes down to research and observation. Taking a device (there are device labs you can check out) and learning about how it handles and comparing with other devices. The experience gained influences how we design/build responsive sites and apps.

    Why does this matter? By using context, we can refine our solution and design to better fit a solution to the problem we need to solve. As a consequence, context will define each of our constraints to accommodate user behavior.

    Yes, it feels time-consuming, but it’s worth it to create a great user experience. There is still a third element that must be considered, though: content.

    Content

    At its simplest, content it the stuff that’s on the page. However, with the ever-changing layouts from responsive design, content must become more sophisticated.

    In thinking about content, we have to remind ourselves that the core concept of the Web is information.

    With the advent of responsive design, we now have a process where we can create websites and apps that can carry the nearly same information without device constraints. However, constraints and context shapes how we view content. It’s not a matter of just hiding or showing words. It becomes a matter of determining what content has the highest priority.

    With changes in layout and the concept of the fold largely negated, we needed to rethink how we place content on a screen. Or I should say, we need to reconsider old ideas about placing content on a screen.

    NASPGHAN homepage with open navigation

    For example, the non-responsive NASPGHAN site has complex, deep navigation. Mentally, you would think that the code for this would come at the beginning of the page. However, because the navigation is so large, it would take a vast amount of space before the content the user wants to read. In this case, code for the navigation is written at the bottom with its position displayed via CSS at the top. If you were to use a screen reader/non-visual tool, you could get to the content readily but still get to the navigation via skip/anchor links.

    When creating content, keep a mobile-first mantra. Design for the mobile site first and let the constraints of a small environment help select the most important content. Then, as the user gains more real estate or features, give them the extra content. Essentially, just let your constraint and context will be a guide in your content selection.

    Prioritizing content creates a flow of information along the screen which aids in how layouts are structured. This, in turn, allows you to adjust content for better solutions to constraints. When creating content for responsive design, the best practices are:

    1. Prioritization – determining what content gets the highest importance
    2. Distribution – determining which content is important enough to cause readers to scroll down.

    A Collaborative Art

    The most important thing that I hope to stress is that responsive design is not a singular effort. As in the jigsaw puzzle at the beginning of this blog post, each project is a combination of the three ‘C’s. A little more content in this project, a little more context in the other. Responsive design is a process that involves many processes and, in some cases, many people to bring it together.

  • Gesture-Based CSS Selectors

    [This is a short, informal proposal of a concept, with a more extensive version in the near future. However, this should be enough for starting discussion on its value/implementation.]

    What are Gesture-Based Selectors?

    Gesture-based CSS selectors are a combination of the current set of CSS selectors/pseudo-selectors to include new set of gestures currently being used in mobile (tap, tap hold, swipe, etc.). The main goal is to give basic interactivity to elements without JavaScript support.

    The closest analog would be the same sort of relationship with CSS3/JavaScript animation. In the current methodology:

    • CSS3 – basic/simple animations, removing the need for JavaScript resources
    • JavaScript/JavaScript Library via Events – complex animations, requiring more functionality beyond CSS3 animations

    Initially, this was just focused to touch gestures. However, this can be also be extended to other "gestures" such as the current JavaScript events "click", "mouse(over/out)", "key(up/down)", etc. This will allow for non-touch gestures → keyboard, voice/speech, inputs from any other devices, etc.

    CSS/Gesture Selectors Format

    The concept is to have these represented in CSS code by the following selector (in two versions, using the mobile gestures swipe left and tap hold as examples):

    1. selector:gesture-(gesture name)

      Similar to :hover, :focus pseudo-selectors (using current

      Examples:
      div:gesture-swipeleft { CSS code }
      a:gesture-taphold { CSS code }

    2. selector[gesture=”gesture name”]

      Similar to attribute selectors, introduced in CSS 2.1 but in use more with CSS3

      Examples:
      div[gesture=”swipeleft”] { CSS code }
      a[gesture=”taphold”] { CSS code }

    Constraints/Problems

    At this point, three initial problems appear:

    1. New Devices/Platform w/ Gestures – some sort of path/procedure needed for recognization of new gestures that is open and flexible. I recommend the following for an initial path:

      Device/Platform Support → JS event support → CSS/gesture selector available

      This will allow for the availibility for selectors mention above. However, there is the problem of device-specific gestures, which could mean that certain selectors will be available for only those devices. Currently, the touch events are only available on touch enable devices. If a [front-end] developer was writing code for a non-touch enabled device, the JS support would be non-existant -> no CSS/gesture support

    2. Gesture Uniformity – if a gesture gains support across platforms/devices, the related CSS selector should never be prefixed as we currently have for CSS3 features like animations or tranforms, ie "-iphone","-android", etc. I recommend this because unlike CSS3 features, these are OS based issues ("native"). The selectors will be device/platform "neutral" – let platforms/devices be solely responsible for interpretation.
    3. Computer Processing – if this gets implemented, how does this effect processor/power usage. How does the current set of CSS3 features (transitions/animations) deal with different computer processing power (hardware accelerators?)

      If this gets added to the current set – will there be a bigger demand for hardware processing? What would this mean for small, less powerful devices? (the drive behind iPhone design and construction).

      Overall – This is an issue that will need to be taken up post-proposal, with people more knowledgeable than me.

    In summary,

    1. Creation of CSS/gesture selectors to allow for basic interactivity, without the need of JS events
    2. Providing a “path” to allow for more gestures, not just current but for future devices/platforms and be platform/device independent.

  • Today, I’m Blowing Up My Code

    Seriously. http://twitter.com/#!/iwilsonjr/status/124622801914171392

    This is not a joke.

    If you are laughing at this, I understand. It still won’t change anything.

    Let me explain.

    In 2009, through contact with interaction designers, I saw the coming wave that we now call mobile. That wave moved so fast that it took everyone by surprise. Today, designers and developers are dealing with this via responsive design and other techniques.

    Now, what does it have to do with me. One day recently, I was tasked to revised some code I made in late 2009. Now, it was good by those standards but it has a few faults. Not perfect but usable and everyone was satisified.

    At the time, it was "Job done. Go to sleep."

    But I didn’t.
