Real web developers take web accessibility seriously. It is part art, techinical, logic and common sense in getting a website accessible for everyone.
Web acessibility for sites developed for mobile phones are accessed differently due to a lot of factors including:
1. Smaller screen size (most obvios reason)
2. Many mobile devices do not support embedded objects or scripts and in many cases it is not possible for users to load plug-ins to add support.
3. Use of tables for layout purposes is considered to be bad practice, particularly for mobile devices.
4. And lots of others.
However, no one is perfect and remembers all of this rule. Luckily, a site known as ready.mobi does all the testing and validation for you. It’s easy, free, fast, and shows you interesting stats such as mobil readiness, load time for different kinds of wireless connection such as WiFi, 3G and GPRS, data size, and what it would cost users to access your site.
