可以跳过标题级别吗？ [英] Is it OK to skip heading levels

问题描述

我一直不赞成在HTML文档中跳过标题级别，尤其是出于屏幕阅读器可访问性的原因。此外，要求页面的结构在没有CSS的情况下有意义，这似乎表明不建议跳过标题级别。例如：

 < h1> ...< / h1> 
< h3> ...< / h3> 
< h4> ...< / h4> 
  

一位同事声称，如果内容的相对重要性反映在标题标记中，那就没有问题。我想他可能是对的。

来自可访问性专家的想法？

解决方案

<我相信在WCAG1下跳过标题水平被认为是可以接受的但并不理想，但WCAG2在这方面更严格。举例来说，屏幕阅读器会公布标题级别，而跳过的数字会使用户看起来好像没有隐藏内容。如果使用CSS来按照自己喜欢的方式进行样式设置，则不需要跳过关卡。

I've always frowned upon skipping heading levels in HTML documents, especially for reasons of screenreader accessibility. Additionally the requirement that a page's structure makes sense without CSS seems to indicate that skipping heading levels is not advised. For example:

<h1>...</h1>
<h3>...</h3>
<h4>...</h4>

A coworker claims that this is fine if the relative importance of the content is reflected in the heading markup. I suppose he could be right.

Thoughts from accessiblity experts?

解决方案

I believe skipping heading levels was considered acceptable but not ideal under WCAG1, but WCAG2 is stricter in this regard. As one example, screen readers will announce the heading level and the skipped number would make it seem like the user had missed some hidden content when they haven't. There shouldn't be any need to skip a level if CSS is used to style the way you'd like.
