Aaron Gustafson

As would be expected from a former manager of The Web Standards Project, Aaron Gustafson is passionate about web standards and accessibility. He has been working on the web for two decades and currently reps the web at Microsoft, where he works closely with the Edge team. He is Editor-in-Chief here at A List Apart and writes about whatever’s on his mind at aaron-gustafson.com.

  • From URL to Interactive

    When we think about it, our whole industry depends on our faith in a handful of “black boxes” few of us fully understand: browsers. We hand over our HTML, CSS, JavaScript, cross our fingers, and hope they render the experience we have in our heads. But knowing how they work can really get you out of a jam when things go wrong. That’s why we’ve assembled a handful of incredibly knowledgeable authors to take us under the hood in this four-part series. Join us on this trip across the web, into the often foggy valley between code and experience.

  • Conversational Semantics

    Semantic markup has always mattered, but with voice interfaces rapidly becoming the norm, it now matters more than ever. Aaron Gustafson shows us how simple HTML tags can have a huge impact with voice interfaces.

  • The Illusion of Control in Web Design

    We think of our job as controlling the user’s experience. But the reality is, we control far less than we imagine. And that’s by design: it’s how the web, and the networks that serve it, are supposed to work. ALA’s Aaron Gustafson shows the many ways our medium conspires to break our carefully crafted experiences, and shares solid advice on what we can do about it.

  • The Story of CSS Grid, from Its Creators

    Designers have used grids for centuries. And after more than 20 years of waiting, they are finally here for the browser. This is the story of CSS Grid. It took a lot of people in the right place and at the right time to make it happen.

  • Yes, That Web Project Should Be a PWA

    A Progressive Web App (PWA) is a website with special powers. Despite what you might have heard, most websites—and, more importantly, their readers—can benefit from becoming PWAs. And it’s so easy! New A List Apart editor-in-chief Aaron Gustafson explains.

  • Interaction Is an Enhancement

    The web has an endless supply of single-point-of-failure horror stories, where sites serve up blank and blocked pages to dumbstruck users. But the fault is not with JavaScript and other technologies—it’s with how we use them, banking on them alone instead of diversifying how we deliver our experiences. In this excerpt from Chapter 5 of Adaptive Web Design, Second Edition, Aaron Gustafson explains why understanding and working within limitations is the key to building resilient websites.

  • Now You See Me

    Showing and hiding content using JavaScript-based page manipulations for tabbed interfaces, collapsible elements, and accordion widgets is a common development pattern. Learn how your choice of hiding mechanism can influence content accessibility in assistive technologies like screen readers in an excerpt from Adaptive Web Design.

  • Stop Forking with CSS3

    You may remember when JavaScript was a dark art. It earned that reputation because, in order to do anything with even the teensiest bit of cross-browser consistency, you had to fork your code for various versions of Netscape and IE. Today, thanks to web standards advocacy and diligent JavaScript library authors, our code is relatively fork-free. Alas, in our rush to use some of the features available in CSS3, we’ve fallen off the wagon. Enter Aaron Gustafson’s eCSStender, a JavaScript library that lets you use CSS3 properties and selectors while keeping your code fork- and hack-free.

  • Progressive Enhancement with JavaScript

    Our introductory series on progressive enhancement and the ways it can be implemented concludes with a look at the mindset needed to implement PE in JavaScript, and a survey of best practices for doing so.

  • Progressive Enhancement with CSS

    Organize multiple style sheets to simplify the creation of environmentally appropriate visual experiences. Support older browsers while keeping your CSS hack-free. Use generated content to provide visual enhancements, and seize the power of advanced selectors to create wondrous (or amusing) effects. Part two of a series.

  • Understanding Progressive Enhancement

    Steven Champeon turned web development upside down, and created an instant best practice of standards-based design, when he introduced the notion of designing for content and experience instead of browsers. In part one of a series, ALA’s Gustafson refreshes us on the principles of progressive enhancement. Upcoming installments will translate the philosophy into sophisticated, future-focused design and code.

  • Beyond DOCTYPE: Web Standards, Forward Compatibility, and IE8

    For seven years, the DOCTYPE switch has stood designers and developers in good stead as a toggle between standards mode and quirks mode. But when IE7, with its greatly improved support for standards, “broke the web,” it revealed the flaw in our toggle. The quest was on to find a more reliable ensurer of forward compatibility. Is version targeting the answer?

  • If I Told You You Had a Beautiful Figure…

    Laying out images consistently within a design is difficult, especially when you hand the keys over to someone else to fill in the content. ALA Staffer Aaron Gustafson demonstrates how a little clever JavaScript goes a long way toward resolving inconsistencies in image layout.

  • Ruining the User Experience

    Anticipating your users’ needs is the key to making a good impression; it’s the little things that matter most. ALA technical editor Aaron Gustafson explains why progressive enhancement means good service.

  • Getting Started with Ajax

    In this excerpt from O’Reilly’s Web Design in a Nutshell, 3rd Edition, ALA’s production editor would like to take you aside for a little chat about the birds and the bees. Or maybe about Ajax.

  • Improving Link Display for Print

    Some time ago, Eric Meyer showed you how to add URIs to the printed version of your pages using print styles. Sometimes, though, too many inline URIs can make pages hard to read. Aaron Gustafson comes to the rescue with a JavaScript add-on that’ll have you loving your linkage again.

  • Let Them Eat Cake

    A growing debate pits accessibility against usability. From our point of view, it’s like pitting peanut butter against jelly. This article helps you create a page that is both usable and accessible, saving readers the trouble of scrolling with a little help from JavaScript and the Document Object Model.
