How can good accessibility help you?
较高的可访问性对你有什么好处？

Having a site that is user friendly is not only good for the visitor it's very good business sense. It's not just about achieving the highest accessibility rating you can it's about making sure your site meets all of your visitors needs.

友好的站点不仅对访问者好，而且，它对你的商业活动也非常有利。你的主要目的并不是为了实现最高的可访问性，而是要确保能够满足访问者的需求。

This in turn means making sure you look at the site and the user experience from the visitor's perspective.

这样概念必须要交替使用确保你是从网站和访问者的目标体验为出发点的。

The reason accessibility is so important is because it allows any visitor regardless of their physical impediments access to your content. Many disabled and visually impaired visitors will not use a conventional browser but an audio browser or other variant that specifically meets their needs. This means that for them to access the content of a site, the information needs to be presented in a suitable way.

可访问性，这点非常重要，如果处理不当，会使访问者无法很好地获取你的站点内容。很多残疾人或是视力不好的人不会使用普通的浏览器，他们可能会使用那些“发声浏览器”或其他那些能够满足他们需求的浏览器。对于他们所访问的站点内容来说，必须要以一个特定的方式来满足他们的信息需求。

Technical considerations for good accessibility
提高可访问性的技术因素

Web site accessibility means allowing visitors to access the content without impediment. These define technical and presentation issues such as:

网站的可访问性应该达到让人们能够很方便地访问网站的效果。具体的技术和表现方式议题如下：

Sufficient contrast between text and background
文字颜色和背景色对比度明显
Ability to re-size text
可以对文本中的字体大小进行调整
Simple HTML hyperlinks for navigation
简单的导航条HTML链接

By using more advanced programming techniques such as "drop down" menus and other dynamic techniques, a barrier can be placed between the visitor and the content. Not only can these techniques represent a usability issue to able bodied users they can present an impenetrable barrier to less enabled visitors.

如果你使用了更多的动态互联网技术，如：下拉菜单，那么，在访问者和内容之间就会造成障碍。这些技术的运用对于正常人来说没什么问题，但是对于残疾人就造成了很大的障碍。

However, there are other good practice techniques such as making links meaningful rather than the ubiquitous "click here" as audio browsers speak the links.

然而，另一种技术的运用也非常不错，可以把链接做成另外一种形式，如：鼠标移动至某个链接上会出现语音提示，而不是简单地用“点击这里”这样的字眼指明链接的方式。

Key benefits of implementing good accessibility practices
提高站点可访问性的好处

Apart from being a "best of breed" site and being legally compliant there are key practical benefits of implementing good web site accessibility practices:

提高站点的可访问性好处多多，它可以使你打破常规的束缚，从最好的同类中脱颖而出：

You are allowing a greater number of people access to your products and services, after all why prevent people parting with their cash. It makes good business sense especially if your site can be more accessible than your competitors.

你可以使更多的访问者访问你的产品和服务，这样你可以他们付钱购买的几率增加。如果你站点的可访问性比你的竞争对手好，那么你的业务量将多于你的竞争对手。
By making your content accessible you remove technical barriers to your content which makes it much easier to re-purpose your content to other platforms such as mobile phones, television and handheld devices

通过提高站点的可访问性，你丢弃了那些会对访问的内容造成障碍的技术壁垒，从而可以使手机、电视和掌上设备操作平台上的内容访问更加简单。
