本书教授了如何建立更易访问的Web站点，并解释了为什么要这样做。虽然增加了前期的工作量，但是潜在的收益却是巨大的，特别是当移动用户需要访问你的站点时。

利用视频和Flash动画，你会发现如何使用基于标准的技术，如XHTML、CSS和Aja，以开发范围更广的用户和设备的应用程序，包括移动Web。有了这本书，你将：学习元数据的重要性，以及元数据如何作用于图片、标题和其他设计元素；建立适用于手机、屏幕阅读软件、文字预测等的窗体；使用色彩和文本创建在多种情况下有效的设计；设计Ajax驱动的社交网络应用程序，以使伤残人士也可以访问；提供有文本的音频及包含字幕和音频描述的视频；发现适用于富互联网应用(RIA)技术的辅助技术支持，如Flash、Flex和Silverlight；

本书提供了一个让你设计出易于管理的Web应用程序的路标，使广大读者受益。
