Phones are turning into real tools for the web, and I want to set down what I am learning, because I think a lot of us are going at it backwards. The mobile web is not a smaller desk. It is a different place, and designing for it as though it were a shrunk-down monitor gets you the wrong thing.
My first website, years ago now, was for Mountain Industrial Safety — for a man named Robin Postnikoff, who took a chance on a beginner and still runs that business today. It was built before anyone was thinking hard about phones, and yet even then, near the start, I had begun to wonder how a site would hold up once a phone was carrying it. The question has only grown since.
The hardest part of early mobile is the sheer variety of small screens, and how little each one can do. Every handset is a different size with different limits, and making something that holds together across all of them is genuinely hard.
The phone also makes you think about input in a way the desktop never did. Tapping out words on a numeric keypad is miserable, and it changes what you can fairly ask of a person. You stop assuming they will happily fill in your form, and you start asking how little you can require of them.
Navigation without a cursor is its own puzzle. On a computer there is a pointer, and with it the hover state — that quiet layer where things respond before you click. On a phone that layer just is not there. There is touch, and hold, and release. The swipe is barely a concept yet. Each is a different gesture, and most of us were not even thinking about them.
It all points the same way. You cannot take a desktop layout, shrink it, and call it mobile. These constraints are not smaller versions of the old ones. They are new, and they ask you to decide, plainly, what a person actually needs in their hand, standing up, with a thumb and a few spare seconds.
I do not think the phone is a lesser screen. I think it might be the more honest one, because it will not let you hide behind space and a mouse and a patient user. It keeps asking the hardest question in the work: what is the one thing this person came to do? On a small screen, that is the only question that matters, and I am learning to love it for asking.
