我无法理解WCAG 2.0条标准1.4.8。
从我理解它基本上说,如果我有一个世代odicetagcode,我将定义背景和文本颜色,我将不得不:
- 为该DIV提供一种彩色拣选工具,以便用户可以更改这些颜色
- “g156:使用具有可用的技术可以改变文本块的前景和背景”
提供一种颜色拾取器,声音非常远,所以我在“G156”上掌握了我的希望。是否是常规的Web浏览器(即,Firefox,Opera等)有资格作为这样的用户代理?
另一个令人困惑的部分是“F24:成功标准失败的常见失败”1.4.3,1.4.6和1.4.8由于指定前景颜色,而无需指定背景颜色,反之亦然“,我排序解释为“只要您为该DIV指定背景和文本颜色,您的安全”。
关于如何解释此WCAG标准的任何想法?
解决方案
Does a regular web browser (ie,firefox,opera etc.) qualify as such an user agent?
According to http://www.w3.org/TR/2010/NOTE-WCAG20-TECHS-20101014/G156, it seems so. It says:
Tests
Procedure
Open the Web page in a browser that allows users to change colors of HTML content.
Change the foreground and background colors in the browser settings so they are different than those specified in the content.
Return to the page and check that that the new specified foreground text and background colors in the browser override the colors specified in the content.
Expected Results
- Check #3 is true.
"as long as you specify both background and text color for that div, you're safe"
I think so. It means don't just assume the background is white, because if you don't explicitly specify it, it might not be.
