Breaking up with media queries

Responsive Web Design ushered in one of the most fundamental shifts our industry has ever seen. Now, nearly six years since Ethan Marcott’s original article was published on A List Apart, we’ve begun to see RWD evolve. And, subsequently our processes, workflows, and tools have begun to evolve as well.

As developers and designers, we’re familiar with change being ever-present. As we address complex problems with solutions such as component-based design and development (aka Atomic Design), we’re faced with wondering: do our browsers’ viewport heights and widths really provide everything we need to inform our atoms, molecules, and organisms?

Enter: element queries – or, as we’ve recently reshaped them: container queries.

We’ll take a dive into what container queries are, how to use them, and when they might win out over our old friend the media query.

  10. “The web’s greatest strength, I believe, is often seen as

    a limitation, as a defect. It is the nature of the web to be flexible, and it should be our role as designers and developers to embrace this flexibility, and produce pages which, by being flexible, are accessible to all.” JOHN ALLSOPP “A Dao of Web Design” ALA #58 - April 7, 2000

  26. IAN STORM TAYLOR “Media Queries are a Hack” http://bit.ly/1CRGquH “Writing

    modular code is about making small objects, and making them self-contained. Media queries don’t let you do that. In most cases, you don’t actually care about the width of the entire document (or screen), you care about the width of your element.”

  28. Element Queries .product { background-color: red; } .product (min-width: 27em)

    { background-color: orange; }

  29. .product { background-color: red; } .product (min-width: 27em) { background-color:

    orange; } @media (min-width: 500px) { .product { background-color: green; } } @media (min-width: 700px) { .product { background-color: blue; } }

  30. .product { background-color: red; } .product (min-width: 27em) { background-color:

    orange; } @media (min-width: 500px) { .product { background-color: green; } } @media (min-width: 700px) { .product { background-color: blue; } }

  32. ❤ Element Queries ❤ Currently, element queries DO NOT have

    native browser support.
  33. None

  34. Polyfills! Rely on data attributes (sometimes) <div class="product" data-eq-pts="small: 300,

    medium: 500"> And attribute selectors (also, sometimes) .container[data-eq-state$="small"], .container[data-eq-state$="medium"] { font-size: 1em; }

  35. Polyfills! elementQuery Tyson Matanich http://is.gd/mRliE5 “Media Queries Are Not the

    Answer: Element Query Polyfill”
 http://is.gd/cotama

  36. elementQuery scans the document.styleSheets collection for CSS rules <nav class="menu"

    min-width="500px"> .menu[min-width~="500px"] { background-color: #eee; } Then, it appends attributes to the appropriate selector(s)

  37. Polyfills! BoomQueries BoomTown http://is.gd/ejubum

  38. BoomQueries Uses JS to target selectors, then applies classes at

    defined breakpoints boomQueries.add('.component', [ [480, "component--md"], [600, "component--lg"] ]); .component.component--md { background: red; } .component.component--lg { background: orange; } Regular, ol’ CSS

  39. Polyfills! eq.js Sam Richard | @snugug http://is.gd/cadeyi

  40. eq.js Data attribute & values in HTML (data-eq-state gets appended

    on resize) <div data-eq-pts="small: 300, medium: 500” data-eq-state="small"> Uses attribute selectors to apply styles .container[data-eq-state$="small"], .container[data-eq-state$="medium"] { font-size: 1em; }

  43. Code Responsibly Progressive Enhancement

  44. Set Your Goals 1. Rock-solid, mobile-first designs and code 2.

    Consider where components will appear

  45. Set Your Goals MEDIA QUERY Use when a module is

    always the full-width of viewport ELEMENT QUERY Use when a module appears in multiple contexts

  46. “Most every component we build has a basic and an

    enhanced experience, though many have one or more middle levels of enhancement as well. The level of enhancement that each component receives is simply based on the features that are supported by a browser” SCOTT JEHL “Grade the Components”
 http://is.gd/RvqtA0

  47. Grade Components, Not Browsers Each component gets a basic experience

    and an enhanced experience. Levels of enhancement are based on features that the browser supports

  48. PE for EQs Consider element queries to be a first-level

    enhancement. Fallback to mobile-first designs that work well in a single-column layout.

  53. http://is.gd/xocuco USE CASES & REQUIREMENTS FOR CONTAINER QUERIES

  54. Recap •We ❤ media queries (but they’re kind of a

    hack) •Viewport size reporting via media queries is sometimes too broad. •We can get a component’s specific context by taking advantage of element container queries. •We can use element container queries today with the help of polyfills & progressive enhancement.

  55. Recap •Update your vocab (container queries, not element queries) •Experiment,

    experiment, experiment
