The mobile-first design methodology is great—it focuses on what really matters to the user, it’s well-practiced, and it’s been a common design pattern for years. So developing your CSS mobile-first should also be great, too…right? 

Well, not necessarily. Classic mobile-first CSS development is based on the principle of overwriting style declarations: you begin your CSS with default style declarations, and overwrite and/or add new styles as you add breakpoints with min-width media queries for larger viewports (for a good overview see “What is Mobile First CSS and Why Does It Rock?”). But all those exceptions create complexity and inefficiency, which in turn can lead to an increased testing effort and a code base that’s harder to maintain. Admit it—how many of us willingly want that?

On your own projects, mobile-first CSS may yet be the best tool for the job, but first you need to evaluate just how appropriate it is in light of the visual design and user interactions you’re working on. To help you get started, here’s how I go about tackling the factors you need to watch for, and I’ll discuss some alternate solutions if mobile-first doesn’t seem to suit your project.

Advantages of mobile-first

Some of the things to like with mobile-first CSS development—and why it’s been the de facto development methodology for so long—make a lot of sense:

Development hierarchy. One thing you undoubtedly get from mobile-first is a nice development hierarchy—you just focus on the mobile view and get developing. 

Tried and tested. It’s a tried and tested methodology that’s worked for years for a reason: it solves a problem really well.

Prioritizes the mobile view. The mobile view is the simplest and arguably the most important, as it encompasses all the key user journeys, and often accounts fo

As a UX professional in today’s data-driven landscape, it’s increasingly likely that you’ve been asked to design a personalized digital experience, whether it’s a public website, user portal, or native application. Yet while there continues to be no shortage of marketing hype around personalization platforms, we still have very few standardized approaches for implementing personalized UX.

That’s where we come in. After completing dozens of personalization projects over the past few years, we gave ourselves a goal: could you create a holistic personalization framework specifically for UX practitioners? The Personalization Pyramid is a designer-centric model for standing up human-centered personalization programs, spanning data, segmentation, content delivery, and overall goals. By using this approach, you will be able to understand the core components of a contemporary, UX-driven personalization program (or at the very least know enough to get started). 

Getting Started

For the sake of this article, we’ll assume you’re already familiar with the basics of digital personalization

Humility, a designer’s essential value—that has a nice ring to it. What about humility, an office manager’s essential value? Or a dentist’s? Or a librarian’s? They all sound great. When humility is our guiding light, the path is always open for fulfillment, evolution, connection, and engagement. In this chapter, we’re going to talk about why.

That said, this is a book for designers, and to that end, I’d like to start with a story—well, a journey, really. It’s a personal one, and I’m going to make myself a bit vulnerable along the way. I call it:

The Tale of Justin’s Preposterous Pate

When I was coming out of art school, a long-haired, goateed neophyte, print was a known quantity to me; design on the web, however, was rife with complexities to navigate and discover, a problem to be solved. Though I had been formally trained in graphic design, typography, and layout, what fascinated me was how these traditional skills might be applied to a fledgling digital landscape. This theme would ultimately shape the rest of my career.

So rather than graduate and go into print like many of my friends, I devoured HTML and JavaScript books into the wee hours of the morning and taught myself how to code during my senior year. I wanted—nay, needed—to better understand the underlying implications of what my design decisions would mean once rendered in a browser.

The late ’90s and early 2000s were the so-called “Wild West” of web design. Designers at the time were all figuring out how to apply design and visual communication to the digital landscape. What were the rules? How could we break them and still engage, entertain, and convey information? At a more macro level, how could my values, inclusive of humility, respect, and connection, align in tandem with that? I was hungry to find out.

Though I’m talking about a different era, those are timeless considerations between non-career interactions and the world of design. What are your core passions, or values, that trans

I am a creative. What I do is alchemy. It is a mystery. I do not so much do it, as let it be done through me.

I am a creative. Not all creative people like this label. Not all see themselves this way. Some creative people see science in what they do. That is their truth, and I respect it. Maybe I even envy them, a little. But my process is different—my being is different.

Apologizing and qualifying in advance is a distraction. That’s what my brain does to sabotage me. I set it aside for now. I can come back later to apologize and qualify. After I’ve said what I came to say. Which is hard enough. 

Except when it is easy and flows like a river of wine.

Sometimes it does come that way. Sometimes what I need to create comes in an instant. I have learned not to say it at that moment, because if you admit that sometimes the idea just comes and it is the best idea and you know it is the best idea, they think you don’t work hard enough.

Sometimes I work and work and work until the idea comes. Sometimes it comes instantly and I don’t tell anyone for three days. Sometimes I’m so excited by the idea that came instantly that I blurt it out, can’t help myself. Like a boy who found a prize in his Cracker Jacks. Sometimes I get away with this. Sometimes other people agree: yes, that is the best idea. Most times they don’t and I regret having  given way to enthusiasm. 

Enthusiasm is best saved for the meeting where it will make a difference. Not the casual get-together that precedes that meeting by two other meetings. Nobody knows why we have all these meetings. We keep saying we’re doing away with them, but then just finding other ways to have them. Sometimes they are even good. But other times they are a distraction from the actual work. The proportion between when meetings are useful, and when they are a pitiful distraction, varies, depending on what you do and where you do it. And who you are and how you do it. Again I digress. I am a creative. That is the theme.
