Users will often look from link lists to extra body to this section for links or content content. Q: Do I need to use all these for every site? A: Nope, these are just examples of the general page elements you might end up using. Remember, each website is different. In all cases, your content and your theme will determine what page elements you end up using in your final layout. Q: Does every site need a theme and visual metaphor? A: The answer is yes and no.

But in most circumstances, your site is going to have some sort of theme, even if it is only expressed through the content Now we can get back to Mark's and writing on the site.

I was hoping for something a little simpler.

You know: header, footer, one sidebar, that sort of thing. Joe: Is there anyway we can reuse some of the work we have already done? Joe: What about Photoshop? We could build the sites there and show him PDF versions of the designs. If he likes them, we already have a leg up on the visuals and imagery needed for the final sites.

We need something we can get to Mark fast! Frank: What if we just draw them on paper? We can sketch them on paper, add a little color, and send them to Mark to get his approval.

They give you a chance to see how colors interact with one another, how interface elements play off one another, how your navigational system looks, how your visual metaphor plays out, and whether content is represented in the best way possible.

Storyboards give you a painless way of catching any potential design problems before you get to the stage where you build your design in XHTML and they become major obstacles. Storyboards are also a great way to play with design ideas and visually brainstorm. Marking them up is one of the advantages of testing designs on paper.

You may even want to create your storyboards in a photocopy of an empty browser window. This is a great way to give your client the necessary context. How can we come up with a design Mark likes?

When you are finished with the colors, tie up any loose ends you have—and Voila! One supremely awesome storyboard! Here is what the storyboard looks like with browser chrome.

This site is a real pain It sure seems like to use without a mouse. Both these users are having problems using the AudioGo site. When you think about disabilities, one of the first things you probably think about is the visually impaired or the blind.

Those disabilities have a huge effect on how your site is perceived. All your visuals become more or less irrelevant The majority of people who are blind use a screen reader to browse the web. A screen reader is a piece of software that reads the text of a website out loud.

Regardless of the product, a screen reader literally reads your page out loud: A screen reader reads text on a webpage based on the HTML markup.

A human can look at a picture and describe Awww Without any other information, all a computer sees is a filename and an extension. How can you tell the computer what your image really is, in a way you think a screen reader might understand?

Most of the time it simply reads the file name If a screen reader sees an image with an alt attribute, the reader reads the value of the alt attribute instead of the image name. Perfect, right? Well, only if your alt text is any good.

Fortunately, good alt text is pretty easy to create. You want a short, descriptive, clear phrase. A human still sees the image of a cute orange kitten. The computer and screen reader now see the alt text and read that instead of the filename. Filename: audio2go-logo. Filename: poppins. Open up index. Then, fire up your screen reader and check out the AudioGo site again.

Any better? What we need is a way to provide additional information about an element, but let a viewer or listener choose whether they want to access that additional information.

The longdesc attribute lets you do just that. Most screen readers let you choose to hear the longdesc page of information. Remember, this is be read more than se still and HTML file A: Nope. Sighted users A: Unfortunately, longdesc is only recognized by newer screen readers. Older viewed by users with screen readers. Thankfully, current versions of text.

Lots of folks out there have trouble with a mouse, or just prefer using the keyboard. That changes everything.

The Web without a mouse? Open up the AudioGo site in your favorite browser. Try getting around on the page just using your keyboard. Can you get around? What order do things appear in? Does that order match up with the visual order of elements on your page?

How did your actual results line up with what your eyes were telling you? Did the Tab key do what you expected? Tabbing from the heading takes us to the 1 2 3 books. Try using AudioGo without a mouse and without your eyes.
