user-select是CSS属性,用于控制用户是否可以选择文本内容。它有三个取值:auto表示用户可以选择文本,none表示用户无法选择文本,text表示只有在文本输入框或类似的区域内可以选择文本。例如,以下CSS代码禁止了网页中所有元素的文本选择功能:
```
* {
-webkit-user-select: none;
-moz-user-select: none;
-ms-user-select: none;
user-select: none;
}
```

-moz-user-select
-moz-user-select is a CSS property that allows developers to control the user's ability to select text within an element on a webpage in Mozilla Firefox. It only works in Firefox and is not supported by other browsers. The possible values for the property are:
- none: disables text selection for the element and its content.
- text: allows text selection for the element and its content.
- all: allows selection of all elements on the page, including the element and its content.
Example usage:
```
/* Disable text selection for a specific element */
.element {
-moz-user-select: none;
}
```
Note: The property is deprecated in Firefox 69 and newer versions. The standard CSS property `user-select` should be used instead, which is supported by most modern browsers.
.sticky > div { -webkit-user-select: inherit; -moz-user-select: inherit; user-select: inherit; }
这段代码是什么意思?
这段代码是用于设置CSS的样式,其中".sticky > div"表示选择所有父元素为sticky类的子元素div,而"user-select: inherit;"是设置用户选择文本时的行为,inherit表示继承父元素的user-select属性。-webkit-user-select和-moz-user-select是针对不同的浏览器内核的兼容性写法。
