Web Design and Graphics

The number of users browsing the Web from a mobile device continues to rise, yet most mobile web sites are still sub-par.

The thing is, creating a great web experience for users of mobile devices is much easier than you might think. In this article I’ll introduce seven fundamental steps that, if followed, will help you avoid the pitfalls that have caused many other mobile sites to fail. By the end of this article you’ll know exactly where to focus your efforts in order to build a successful mobile site.

1. Don’t Mix Up Your Markup

A few different types of markup are available for building a mobile web site. You’ll need to choose one that suits the needs of your customers and stick with it.

WML

In the early days of mobile web devices, the only way to surf the mobile web was to browse WAP (Wireless Application Protocol) sites. A WAP site uses WML (Wireless Markup Language) as its primary markup language. WML is an XML markup language based on the card-and-deck metaphor.

Luckily for us, WML has since been superseded by several other technologies — in fact, if you’re just getting into the mobile web game, you can probably ignore WML entirely. WML is mostly used by legacy systems or by sites that explicitly target customers with low-end phones that are six years old or older.

One potential group of customers still using WML browsers, however, is those in developing nations. TheNokia 1100 and 1101, for example, are extremely basic, extremely cheap phones, of which an estimated 200 million units have been solid worldwide, making this phone the best-selling model to date, worldwide. If your site is targeted to this market segment, WML might be the best solution for you.

XHTML

For most sites, we can ignore WML and make use of a markup language with which you’re probably much more familiar — XHTML.

Most built-in phone browsers these days can handle XHTML just fine. A mobile phone recognizes two flavors of HTML:

1. XHTML — the same, basic XHTML rendered by desktop web browsers




2. XHTML-MP — the MP here stands for Mobile Profile

The difference between these two languages is that XHTML-MP consists of slightly fewer elements and tighter restrictions. These differences exist to make it easier for the mobile device to parse and render a web document, but writing XHTML-MP markup shouldn’t introduce any significant changes to your process for writing regular XHTML.

Anecdotally, when my team and I develop mobile web sites we usually use regular XHTML, and this approach has served us just fine.

2. Know Your Phones

As plasma and HD TVs slowly hit the market, broadcasters have run into the problem of where to place their logo and news tickers. Previously, they knew that all TVs were the same 3×2 dimensions, so they knew the relative width of the screen. Now, they’re beginning to feel the pain of dealing with a wide assortment of TV resolutions and dimensions — an issue that web developers deal with on a daily basis.

Of course, the mobile world is even worse! Not only must we cater for different screen sizes and resolutions, but also different shapes, as Figure 1 illustrates. From rectangles that are short and long, to those that are tall and skinny, to perfect squares, the mobile world contains a rich tapestry of variation that almost makes you want to pull your hair out!

If you consider the most common phones available, they can be categorized on the basis of screen size — give or take a few pixels:

• 128 x 160 pixels
• 176 x 220 pixels
• 240 x 320 pixels
• 320 x 480 pixels

Knowing these screen dimensions helps you optimize some of your content, however it’s best to keep the shape and style of your site as minimal and linear as possible. There is no mouse on a mobile phone — only an up-down feature — so you can’t demand that users jump around the page.

iPhone/Internet-tablet versus old green-screen phones

There are a couple of exceptions to the norm in the mobile phone market. They are the really high-end devices like the iPhone or the Nokia Internet Tablet, and the very basic, old “green-screen” monochrome dot matrix devices such as the Nokia 3310,

Low-end mobile phones have several limitations, including screen resolution and a severely limited ability to render XHTML documents. As I mentioned in the previous section, if a majority of your customers fall in this group, then maybe WML is still for you.

At the other end of the spectrum, high-end devices often have the ability to run a web browser that’s comparable to one you might use on a desktop machine. Delivering a quality user experience to these devices can be tricky — while the device may be perfectly capable of rendering a full, traditional web page design, it’s probably transmitting data over a cellular network, which is much slower than standard broadband Internet speeds. So even though the device can handle a normal web site, the customer’s situation and the reason why they’re requesting your services may mean that sending them the normal version of your web site isn’t the best solution.

We’ll see in the next section what this means for the design of your mobile site.

3. Target the Right Customers

The goal for any web site should be to know your customers in order to deliver to them the most appropriate content.

This goal is even more important with mobile sites — not only do you need to know your customers, but you need to know what they are likely to be doing on your mobile site, as well as where they’ll be when they’re doing it. Traditional web site customers are most likely sitting at a desk facing a large monitor that has a decent resolution. Visitors who are browsing your mobile site are unlikely to be in the same circumstances — they might be waiting in line, riding on the train or the bus, running to the departure gate, or lost in an unfamiliar town late at night and trying to get somewhere.

Google is one company that has invested considerable effort into streamlining its web applications to suit mobile users. The web developers at Google have identified and focused on three main groups, and they attempt to target their applications to those customers’ needs. These are three solid categories, and are worth examining for your own mobile site. Let’s look at them now.

The Number 1 rule that every web designer should follow is to create a fast loading web site. You might have a great design but very few people are going to see it if it takes a long time to load. While designing a web site always think about how long it will take to load. Try out our tips to build a great looking web site that also loads fast.

1. Minimize the use of images - The key to a fast loading web site is to minimize the use of images. Images do enhance a page but don’t make 80% of your web site only images. Instead break it down as much as possible to simple HTML. Notice the popular sites like Yahoo, Google, Ebay, Amazon etc., they have very few images because the load time is more important. Very often simple designs are the best.
2. Optimize images for the web - Once you have decided on the images that you need on your site, make sure that it is optimized for the web. They should be in the gif or jpeg format. You can also minimize the size of the image by choosing the number of colors you need, from the color palette. The less the colors you choose, the less the size of the image. You can also use online tools like Gif Wizard to optimize your images or to get a recommendation on how to cut down the size of an image.
3. Use Tables creatively - You can get some great looking designs by using tables creatively . Tables load very fast because it is just HTML code. Tables can be used in the homepage, menus or anywhere you like. Check out our homepage and our menus to see how we have used tables in our site.
4. Cut down the use of animated gifs - Don’t use animated gifs unless it is necessary. Animated gifs take a long time to load and can also be very irritating. But since they catch your attention you could use small animated gifs to draw a visitor’s attention to a particular section of your site.
5. Design simple icons - Instead of using big, bulky images use simple and small icons that add a little color and draw the attention of a visitor.

1. Use background images instead of big images whenever possible - Use background images whenever possible. This is usually a very useful tip for headers and footers. Instead of using an image of width 580 which is a uniform design you can use just a part of that as a background fill. This reduces the size of the web page as the image is small. The code will look like this : <tr background=”/images/header_backgroud.gif” width=”100%”>
2. Try out CSS Styles - Have fun with CSS styles to get some cool text effects. Again, a CSS Style is simple HTML code so it loads very fast. You can create cool rollovers using CSS Styles.
   Rollover the text on the right menu to see how we have used CSS Styles to get a simple but nice text effect.
3. Use Flash sparingly - There seems to be a lot of hype about Flash but I recommend that you minimize the use of Flash on a site. Don’t make entire sites using Flash. It may look great but it takes hours to load and can really put off visitors. If you do want to use Flash use it within an HTML site and make sure it loads fast.
4. Design most of your site in HTML - As much as possible try to design your site using HTML. You can create great designs by just using HTML code. Use tables, CSS Styles and simple fonts to design your site. Minimize the use of animated gifs, Flash, bulky images etc.
5. Keep checking your load time - Last but not least, before you decide on the final design of your web site, check its load time on NetMechanic. This site gives you a free analysis of your web site which is extremely useful. We kept using it to improve our site till we got a report that said good loading time!

We learnt these tips while building our web site. We’ve enjoyed sharing them with you and hope that you found them
