Apple-Specific Meta Tag Keys.
You can use Hypertext Markup Language (HTML) in conjunction with other web content technologies to deploy cross-platform media-rich interactive content to a variety of sources. HTML documents—which can be anything from a textual product description to a photo library to an interactive form—can be read by web browsers on every common platform, displayed and interacted with on portable digital devices, and integrated into WebKit-based applications in Mac OS X, along with a variety of other technologies.

This document details every HTML tag and property supported by WebKit and Safari on all platforms, which include Mac OS X, iPhone OS, and Windows. You should read this if you are developing web content that will be displayed in Safari or within a WebKit-based application.

Front-end web developent can seem to be easy at first, but producing a clean, semantic, and cross-browser code is definitely a hard job. In this article, I have compiled the top 10 best practices that have been useful to me in the past 3 years.

For instance:
- The iPhone is 320 pixels wide by 480 pixels high.
- Many Nokia N-Series devices are 240 pixels wide by 320 pixels high.
- Newer devices often support a landscape mode where the width and height are spontaneously reversed.
- Older (yet still popular) Nokia devices have displays ranging from 176 by 208 pixels up to 352 by 416 pixels
- Blackberry screen resolutions range anywhere from 160 x 160 pixels all the way up to 324 x 352 pixels.
