The ::selection CSS pseudo-elementapplies rules to the portion of a document that has been highlighted (e.g., selected with the mouse or another pointing device) by the user.

的::选择CSS伪元素应用规则到已经强调了一个文件的一部分（例如，使用鼠标或其他指针设备选择）由该用户。

The default depends on the browser you are using. It's usually somewhere around #3297fd.

默认值取决于您使用的浏览器。它通常在附近的某个地方#3297fd。

You can change it like so:

你可以像这样改变它：

/* draw any selected text yellow on red background */
::-moz-selection { color: gold;  background: red; }
::selection      { color: gold;  background: red; } 

/* draw selected text in a paragraph white on black */
p::-moz-selection { color: white;  background: black; }
p::selection      { color: white;  background: black; }

The selection background colour? That doesn't really have anything to do with the browser, it's an OS setting (and is generally customizable). If you really want to know the specific blue on your machine, screen cap it and open it in any graphics program that lets you inspect colour.

选择背景颜色？这与浏览器没有任何关系，它是一个操作系统设置（并且通常是可定制的）。如果您真的想知道机器上的特定蓝色，请对其进行屏蔽并在任何可以检查颜色的图形程序中打开它。
