Computer World报道说Gmail许多新功能都将基于HTML5进行搭建。Gmail工程师Adam de Boor说，Google的目标是将Gmail的载入时间少于1秒钟。

如果浏览器支持CSS3的话，Gmail可以使用这个新的脚本的特性，而不是利用DOM传统载入方式。Google发现使用CSS3可以让速度提升12%。Gmail还将使用HTML5的数据库标准。现在邮箱服务使用Google Gears来存储离线邮件，但是Google将在不远的将来要转移到HTML5标准上。

另一个新功能将允许用户拖拽附件（如同Mac OSX一样）至桌面。虽然这项功能在HTML5中暂时没法实现，但是Google会鼓励其他浏览器支持此项功能。目前，你可以在Firefox和Chrome上使用这个新特性。

Gmail工程师说目前Gmail有443000行的JavaScript是人工手写的。

目前Gmail的很多功能只能在桌面的客户端使用：比如从其她帐户收取邮件，离线信息。是时候将Gmail与浏览器或者操作系统更好融合了。

Computer World reports that many of the upcoming Gmail features will use HTML5. Adam de Boor, a Gmail engineer, said that Google’s goal is to make Gmail load in less than a second.

“If the browser supports CSS3, Gmail will render the pages using these specifications, rather than its traditional approach of using the Document Object Model (DOM). The company has found that using CSS3 can speed the rendering time by 12 percent. (…) Gmail will also make use of HTML5′s database standards. Now, the e-mail service uses Google Gears to store mail for offline reading, but over time that will migrate to the HTML5 standards.”

Another feature that will be added to Gmail allows users to drag attachments to the desktop. This feature is not part of HTML5, but Google says that it will encourage other browsers to use it. Right now, you can drag and drop files from the desktop to Gmail, but only if you use Firefox 3.6 or Chrome.

Adam de Boor revealed how many lines of code are in Gmail: 443,000 lines of JavaScript code written by hand.

Gmail has added many features that used to be available only in desktop mail clients: fetching email from other accounts, threading, powerful spam filters, reading messages offline. Now it’s time to better integrate Gmail with the browser or the operating system and to add notifications, a simplified way to handle attachments and a better performance.
