Web Design: A Look Back

Ray Drainville

Serge Keller has compiled a series of screenshots of early websites. How far have we come?

Alta Vista in 1996 wasn’t a million miles away from Google today. Visually speaking, that is. Apple in 1997, however, shows how much things have changed:

It’s been a while since I’ve seen this. I think it interesting the lack of change for “harder” information gleaning, à la Alta Vista & Google. Only recently has Google been modifying its look. Information services is clearly a very conservative field.

Implications of Responsive Web Design

Ray Drainville

Web designers who are interested in providing an optimal experience for viewports of widely-varying width—I’m looking at you, traditional computers, iPhone & iPad—will be very interested in responsive web design.

A term coined by Ethan Marcotte in a revolutionary article (and compelling read), responsive web design takes together a number of elements that have been rattling around recently—CSS3 media queries, fluid grids, flexible images, in particular—and Marcotte showed how they can interact with one another to provide a powerful web presence across widely varying viewports. Since then, he’s expanded upon the subject by publishing a book. It’s the single best place to go in order to get up-to-speed on the subject—although, like all “A Book Apart” titles, it’s woefully small & at best a very general introduction to the subject.

I’ve just completed the process of converting a site I’ve been working on to a responsive design. This site is an ideal candidate for a responsive web design approach in that it’s an academic site & the participants, the prime candidates to access its content, are all around the world. The site provides information about upcoming workshops, meaning that the target viewers (participants in the academic project) are very likely to access the site’s content while using handheld devices such as the iPhone or iPad. As such, I received a nice introduction into the subject, particularly with the real-world repercussions.

Janus Cascade

One thing that I didn’t notice in Marcotte’s article or book is that by wrapping our designs in media queries, a style’s cascade is now two-facing. There are massive implications with this approach, and if you take a pixel-based approach, as opposed to the percentage-based approach Marcotte takes, all hell breaks loose. Here’s an example to show what I mean:

Say you have a DIV & when the viewport is a desktop size, you want it to be 100 pixels & float left; but on an iPad’s portrait mode, you want it to remain the same size & float right; and finally, on an iPhone portrait mode, you want it to be 300 pixels & display as a block. Here’s how you might go about that:

  @media screen and (min-width: 1040px) { /* For Traditional Computers */
    div { width: 800px; float: left; }

  @media screen and (min-width: 810px) { /* For iPad: Portrait Mode */
    div { float: right; }

  @media screen and (min-width: 320px) { /* For iPhone: Portrait mode */
    div { width: 300px; display: block; }

If you looked at the page with the DIV in question in your various viewports, everything would seem to be OK. But for the sake of experimentation, on your desktop machine, resize your browser window.

You’d be in for a shock if you resized your browser window. When the browser’s wide, then the DIV is big & floats left. Shrink the window & the DIV floats right. What happens when you make the browser really small? Well, actually, it’ll still float right because you haven’t overridden the iPad portrait mode declaration. Now refresh your tiny browser window & you’ll see that the DIV now displays as a block. That’s because it’s not cascading the iPad portrait mode’s float declarations, because that condition hasn’t been met in your refresh. As Keanu Reeves would say: Whoah!

Now start resizing the window from that tiny width. You’ll notice that your floats aren’t floating, but displaying as a block; and furthermore, your box has not jumped to 1000 pixels in width, but has remained at 300 pixels. Again, it’s because you’re inheriting the display: block from the iPhone portrait mode declaration. See? Cascades now work two ways, depending upon how you resize. Double whoah! The solution here is to explicitly state in your iPad portrait mode that you want the div at 800px & also declare in each case where you want the DIV to float & how it’s to be displayed in the document flow.

Go With Percentages, Not Pixels

The other implication that I’ve only grazed above: working in pixels is a bad, bad idea. This is the reason why Marcotte exclusively refers to items in percentages: it’s a more elastic approach & won’t fall apart quite as thoroughly as pixel-based approaches. And in my experience, when I switched from pixels to percentages, the site coalesced really quickly.

Go Forth Warily

Freaky deaky responsive web design: you probably have a lot more testing to do now. And for Internet Explorer (prior to version 9, which is very good), you’ll need some help for reading media queries.

Make no mistake: responsive design is the future of web design & with the explosion of handheld devices, it’s very much worth it: no longer will you have to design multiple sites for different classes of devices. In fact, the first non-personal site, the Boston Globe, has just launched as a responsive site, and the power of this unified approach is self-evident.

Ray on BBC Radio Sheffield

Ray Drainville

Since we’re coming up to the tenth anniversary of the September 11 attacks in New York & Washington, and that I’m from the United States, BBC Radio Sheffield interviewed me about what I remember of the day. Specifically, I was called to the BBC studio that day & that’s where I saw World Trade Centre towers collapse; my father was in Manhattan when the attacks occurred & I couldn’t verify his safety for days; and my in-laws, who are physical anthropologists, worked with DMORT to recover bodies for months at the “Fresh Kills” landsite. This is all covered in the interview which you can download.

The thing that really hits me is that so many people saw the attacks live: not the first plane, of course, but there were many watching the aftermath of the first crash at the World Trade Centre when the second plane hit. I think that’s why our reactions are so strong: we saw it unfold, and we all slowly realised the significance of the acts we witnessed. Unfortunately, I didn’t get the opportunity to talk about the legacy of 9/11, which includes the war in Afghanistan, the justification for the war in Iraq, the death of countless civilians, the erosion of civil liberties, the advocacy of torture, the draining of the US’s material wealth, the continuing inflammation of anti-American sentiment abroad and the decline of American power. It’s a bloody and unspeakably tragic legacy. In any event, if you want to hear someone saying “uh” & “ah” a lot, have a listen.
