Description
The objective of this technique is to demonstrate how to group links into logical sets. When links are grouped into logical sets (for example, in a navigation bar or main menu that appears on every page in a site) they should be marked up as a unit. Navigation bars are usually the first thing someone encounters on a page. People who are sighted are often able to ignore navigation parts and start reading the content of the page. Someone using a screen reader must first listen to the text of each link in the navigation bar before reading the interesting content. There are several ways to mark up content so that a user with a screen reader can jump over the navigation bar and avoid reading all of the links.
Group links via one of the following mechanisms (in descending order of preference):

描述
客观的这项技术是为了演示如何组联系到逻辑套。当环节分成逻辑集（例如，在导航栏或主菜单中出现的每一个页面在一个站点） ，他们应标明了作为一个单位。导航酒吧通常第一件事，有人就遇到了一页。人都是短视往往能够无视导航零件，并开始阅读的内容页。有人用屏幕阅读器，必须先听听文每个环节，在导航栏前，阅读趣味十足的内容。有几种方法，以标示内容，使用户与屏幕阅读器可以跳过导航栏，并避免读所有的链接。
集团链接通过下列情形之一的机制（降序按优先顺序排列） ：
