网络可访问性 [英] Web accessibility

问题描述

因此，我们应该创建可访问的网站，为img元素和所有其他内容提供alt属性。但是，尽管这样做影响的用户数量相对较少，但我找不到影响每个用户的问题的任何信息。

So we should make accessible web sites, providing alt attribute for img elements and all other stuff. But although this effects comparatively lesser number of users, I could not find any information to the issues that effects each and every user.

让我解释一下。如果我们通过说网站应该在最短的时间内提供最真实的信息来简化事务，我会错吗？鉴于此，我愿意

Let me explain. If we were to simplify matters by saying that web sites should provide the most revelant information in the least amount of time, would I be wrong? Given this axion if I were to

1-想要下载Acrobat Reader X的脱机版本。没有任何内容，我的意思是网站 http://www.adobe.com/products/reader.html 提供提示，链接或其他任何内容对此。我必须使用Google查找 ftp://ftp.adobe.com/pub/adobe/reader /

1 - Want to download the offline version of Acrobat Reader X. There is nothing, and I mean nothing on the site http://www.adobe.com/products/reader.html which provides a hint, link or anything to that. I have to use google to find ftp://ftp.adobe.com/pub/adobe/reader/

2-再次尝试在 http://www.google.com/chrome/ 。没有什么可能导致 http://www.google.com/chrome/eula .html？standalone = 1

2 - Again trying to find the offline version of Google Chrome at http://www.google.com/chrome/ . Nothing there that may lead to http://www.google.com/chrome/eula.html?standalone=1

3-Internet Explorer有一个名为Web Developer Tool Bar的插件。可以确定我会在 http://www.ieaddons.com/in/ 上找到它。没有这种运气。必须再次对其进行Google搜索，然后在 http://www.microsoft.com/downloads/zh-CN/details.aspx?FamilyID=95e06cbe-4940-4218-b75d-b8856fced535

3 - So Internet Explorer has an addon called Web Developer Tool Bar. It is safe to assume I will find it at http://www.ieaddons.com/in/. No such luck. Have to google it again and find it at http://www.microsoft.com/downloads/en/details.aspx?FamilyID=95e06cbe-4940-4218-b75d-b8856fced535

4-尝试从 https：//addons.mozilla中获取Firebug插件。 org / zh-CN / firefox / extensions / web-development / 。成功导航到Web开发。您可以使用查看所有添加的评论或查看所有热门下载或查看所有最高评价。如果您想查看所有有关Web开发的信息怎么办。当然，您要起诉搜索！

4 - Trying to get the the Firebug addon from https://addons.mozilla.org/en-US/firefox/extensions/web-development/. Successfully navigated to web development. You can use "view all recetally added" or "view all top downloads" or "view all top rated". What if you want to view all for web development. Offcouse you sue the search!

这些只是其中一些情况。我想我的问题是这些不是可访问性问题吗？

These are just some of the situations. I guess my question would be that are these not accessibility issues?

推荐答案

如果您要描述的问题同样适用于发现用户，而不是使用屏幕阅读器的盲用户，那么不，它们不属于可访问性问题，但可能是更广泛的可用性问题。

If the issues you are are describing apply equally to say sighted users as to blind users using a screenreader, then no, they are not considered to be accessibility issues, but are perhaps broader usability issues.

例如，adobe该网站根本没有到脱机版本的链接，所有用户（无论是否看到）都必须做额外的工作才能找到它，这是可用性问题。

If, for example, the adobe web site had no link at all to the offline version, and all users, sighted or not, had to do extra work to find it, that's a usability issue.

如果网站上有可见的用户可以看到的图形图像是下载链接，但是使用屏幕阅读器的用户没有获得此信息（例如，因为该图形没有ALT文本，或者该图像无法通过键盘操作） ，那么这就是可访问性问题。

But if the web site had a graphic image that sighted users could see was a link to the download, but users using a screenreader did not get this information (eg. because the graphic had no ALT text, or the image was not operable via keyboard), then it's an accessibility issue.

这些之间肯定存在重叠；而且通常情况下，残障用户很难解决可用性问题；但是一般来说，可访问性是指网站的设计在面对残障用户时会遇到障碍或挑战，而无残障用户则必须面对这些障碍或挑战。

There's certainly overlap between these; and it's often the case that usability issues are harder for disabled users to work around; but generally accessibility refers to cases where the design of a site confronts a user with a disability with additional barriers or challenges beyond those that users without a disability have to deal with.
