[LINK] Perspective, by Adactio

If you haven’t, you should immediately read Jeremy’s post titled A responsive mind. Not because he says some incredibly kind things about yours truly, but, well, of bits like this:

That’s the thing about responsive web design: you can’t just think of it as a sprinkle of pixie dust that can be applied to any site. It requires the right mindset. It requires that sites be built on solid foundations of best practice. If those foundations are in place—a flexible layout, flexible images, optimised performance—then responsive web design can work its magic.

There are so many wonderful, quotable points that I’m doing Jeremy a disservice by even excerpting that one. If you’d like to understand why a responsive approach would be right for your project (or, perhaps as importantly, why it might not), I urge you to read the whole thing.

[LINK] A new design for Mark Boulton

Words to tattoo on your knuckles:

Over the past couple of years, my blog hasn’t felt my own, to a degree. It’s felt like I’ve been writ­ing for an audi­ence, post­ing stuff for oth­ers rather than myself. That’s arse-backwards. A blog should be about per­sonal expres­sion. The moment you start think­ing, and writ­ing, to please oth­ers then it’s a bind; it feels less like a per­sonal exer­cise and more of a job.

A beautiful, thoughtful redesign from Mark Boulton (and a responsive one at that). Go go, read read.

[LINK] Fluid Inconsistencies

Front-end developer Steffan Williams of Gridinator fame digs into some of the rendering inconsistencies across various browsers when dealing with percentage-based widths. Now, I don’t think this is a real problem for flexible, grid-based layouts or properly responsive designs. Some of these rounding issues won’t necessarily manifest themselves in your work, or at least not quite as noticeably.

I was, however, emphatically raising my fist in the air when I read this:

While I’m well aware that things don’t have to look the same in every browser, it just seems to strike me as odd that CSS3 features keep getting touted on the front of browser homepages, and yet something as fundamental as a percentage would be rendered incorrectly (or, rather, not as well as would be expected).

Emphasis mine. Much of the behavior Steffan notes was outlined by John Resig in 2008, nearly three years ago. There are some incredible inconsistencies at play here, and designers really shouldn’t have to shoulder the burden of working around them.

In short, some broad consensus between the different rendering engines needs to be reached—and if it comes at the expense of pushing the Next Hot Bleeding-Edge Experimental Sexy CSS3 Feature™ to market, I’m all for it.

[LINK] Responsive images

Since striking out on my own, much of my time’s been dedicated to, well, the book. But I’ve also been fortunate enough to collaborate a bit with Filament Group on one of their projects: namely, a large-scale engagement that requires a responsive approach.

Needless to say, I am having the time of my life.

We’re also learning a lot, too. A lot of discussions about approach and execution have come up, largely because processes for a lot of this stuff don’t exist yet. That will, with a bit of hard work and community discussion, change over time. Still, there has been a lot of brilliant stuff created so far.

Here’s just one example:

The goal of this technique is to deliver optimized, contextual image sizes for responsive layouts that utilize dramatically different image sizes at different resolutions. Ideally, this approach will allow developers to start with mobile-optimized images in their HTML and specify a larger size to be used for users with larger screen resolutions — without requesting both image sizes, and without UA sniffing.

Check out the script, download it, and kick the tires a bit—feedback and tweaks are most welcome.

I realize that there are always going to be philosophical differences around responsive web design. But for me, the solutions-driven discussions are always going to be infinitely more interesting to me than the alternative.

[LINK] Mark Boulton on “A Richer Canvas”

I won’t lie to you: I might’ve pounded the table emphatically a few times while reading Mark Boulton’s latest entry:

We can now design effective adaptive layouts that respond to their environment. If these layouts are based on a system that defines its ratios from the content, then there is connectedness on two levels: connectedness to the device, and connectedness to the content.

Mark’s thinking about flexible, content-driven grids has me damned excited about his upcoming talk at AEA Boston, and you know I’ll be flinging fistfuls of lucre at my laptop screen whenever his new book’s available to preorder.

The web really feels fun again.

I’m doing a disservice to this lovely interview with Shaun Inman—one of my favorite designers and people—by quoting it, but, well:

Curiosity or that unpleasant feeling of leaving something unfinished usually draws me back to a problem or task before too long.
