Developing webpages for mobile devices

[Ed Zachary]

1. You would use the same tool that you used to build the web page in the first place. I usually used Visual Studio or Notepad.
2. Most important tip, limit graphics (number and size). Make the page small enough so it is at least a close fit without the user having to do a lot of horizontal scrolling.
3. Dedicated to converting desktop-targeted web sites to ones targeted at mobile devices? Not many, if any. Usually whoever builds the "full-size" site builds the portion of the site for mobiles.
4. No such thing. Browsers, in and of themselves, do not modify the source for web pages. They simply browse. That is, they receive the page script and render it.
5. No such thing.

What usually happens is that whoever develops the "full-size" web site also builds a version that is mobile browser friendly.
The web pages include code that detects the type of browser and, if a mobile browser, redirects the user to the "mobile" version of the site.

There is no need to customize a phone or PDA, other than installing a browser, to make the device capable of viewing web pages.
