HTML文档或CSS树的深度有多大？ [英] Is there a limit to how deep an HTML document or CSS tree can be?

问题描述

我一直在想这个，因为我有一些非常深的HTML结构。我的观点是：

• 对HTML的嵌套层数有最大限制吗？


• 与CSS类似 - 我需要从HTML DOM树的叶节点中选择东西？


• 是否依赖于浏览器？

感谢您的帮助，

James

解决方案

XHTML 1.0 和 HTML 4.01 规范定义了嵌套限制。 HTML5尚未标准化，但工作规范未提及限制。

CSS 2 规范同样包含没有限制。

基于浏览器的限制可能是未来的一个问题，但我无法用现代浏览器找到任何问题报告。

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

• Is there a maximum limit to the number of nesting levels for HTML?
• Likewise with CSS - I need to select stuff from the leaf nodes of the HTML DOM tree?
• Is it browser dependent?

Thanks for any help,

James

解决方案

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.

The CSS 2 spec similarly contains no limit.

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