低层兼容性LLC ？
我还在更新CSS3的预览内容，并且即将面世的仅仅是那些在低层次实现的、兼容主流浏览器的CSS3新特性。
I’m in the process of updating the Preview area at the moment ( sneak preview), and what’s immediately apparent is the low level of implementation of the new CSS 3 features across the major browsers.
对于将Ajax应用程序开发的一些低层方面(如跨浏览器的不兼容、DOM事件模型和进行Ajax调用)抽象出来，GWT做得很好。
GWT also does a good job of abstracting away some of the low-level aspects of Ajax application development, such as cross-browser incompatibilities, the DOM event model, and making Ajax calls.
