HTML文档或CSS树的深度有限制吗?

I've been wondering this for a while, because I've got some pretty deep HTML structures going on. My points are these:

我一直在思考这个问题，因为我有一些非常深入的HTML结构。我的观点是:

Is there a maximum limit to the number of nesting levels for HTML?
HTML的嵌套级别的数量有最大限制吗?
Likewise with CSS - I need to select stuff from the leaf nodes of the HTML DOM tree?
同样的CSS——我需要从HTML DOM树的叶子节点中选择东西?
Is it browser dependent?
它是依赖于浏览器吗?

Thanks for any help,

感谢任何帮助,

Neither the XHTML 1.0 nor the HTML 4.01 specification defines a nesting limitation. HTML5 is not yet standardized, but the working spec does not reference a limitation.

XHTML 1.0和HTML 4.01规范都没有定义嵌套限制。HTML5还没有标准化，但是工作规范没有引用限制。

The CSS 2 spec similarly contains no limit.

CSS 2规范同样没有限制。

Browser-based limitations may be an issue in the future, but I was unable to find any problem reports with modern browsers.

基于浏览器的限制在未来可能是一个问题，但是我无法用现代浏览器找到任何问题报告。

I'm going to lean toward no limit that I'm aware of. You should check this one out: http://www.geeksaresexy.net/2009/09/01/a-hidden-gem-in-html/. The site is nested deeply enough to recreate a skyline using font tags.

我将向我所知道的无限倾斜。您应该检查一下这个:http://www.geeksaresy.net/2009/09/01 /a-hidden- gemin -html/。这个网站嵌套的很深，可以使用字体标签重新创建一个天际线。

I think you'll hit memory limitations before you hit any DOM restrictions (if any exist; I believe they don't).

我认为在遇到任何DOM限制之前(如果存在的话;我相信他们不会)。
