CSS类名称中的随机字符 [英] Random characters in CSS class names

问题描述

我注意到一件事.在某些网站上，例如tray.io，asana，fb等，当您检查它们时，它们在css类名中具有随机字符，例如:

I have noticed one thing. On some sites such as tray.io, asana, fb etc They have random characters in css class names when you inspect them for example:

<header class="Header_XSDsdksdXKkSDD">..</Header>

为什么生成这些字符以及如何生成它们?

Why are these characters generated and how are they generated?

谢谢.

推荐答案

那些类名或标识符可能是由产生页面输出的引擎生成的.

Those class names or identifiers are probably generated by the engine that produces the page output.

如果要向特定元素添加样式，则需要一个唯一的类-最简单的方法是生成一些伪随机标识符.

If you want to add a style to a particular element, you want a unique class for it - the easiest way is to generate some pseudo-random identifier.
