HTML special characters in CSS "content" attribute
提问by sethvargo
I'm trying to add content to something before an item using the CSS :before + content: fields. I want to insert a checkmark (☑), BUT if I use that in the content option, it prints as the literal. How can I tell CSS to make that a checkmark, not the literal string ☑?
我正在尝试使用 CSS :before + content: 字段在项目之前添加内容。我想插入一个复选标记 (☑)，但是如果我在内容选项中使用它，它会打印为文字。我如何告诉 CSS 将其设为复选标记，而不是文字字符串 ☑？

Try this:
尝试这个：
#target:before {
content: "11";
}

You need to use Unicodevalues inside the contentproperty. (The list of miscellaneous symbolsmay also be useful.)
您需要在属性中使用Unicode值content。（杂项符号列表也可能有用。）
A heavy checkmark is listed as U+2713so you would put content: "\2713";
列出了一个沉重的复选标记，U+2713所以你会放content: "\2713";

Use the checkbox character literally in your CSS rule instead of the encoding -
在 CSS 规则中逐字使用复选框字符而不是编码 -
#target:before {
content: "?";
}
