HTML 符号代码

Q: 什么是 HTML 实体？

以 & 开头、以 ; 结尾的简短代码，例如 ♥ 对应 &hearts;，© 对应 ©。浏览器会显示符号，而不是代码。

Q: 应该使用命名代码还是数字代码？

两种写法在所有现代浏览器中都能正常使用。♥ 这样的数字代码适用于每个 Unicode 字符，而名称只有部分字符才有。在 UTF-8 页面中，也可以直接粘贴符号本身。

Q: 如何用 CSS 添加符号？

在伪元素的 content 属性中使用 CSS 代码，例如爱心用 content: "\2665";。

252 个符号的 HTML 命名实体、十进制和十六进制代码以及 CSS 代码。点击符号即可复制符号，点击代码则复制代码。

如何使用 HTML 符号代码

直接把实体或数字代码写进 HTML 即可，例如 <p>I &hearts; Unicode</p>。命名实体更易读；♥ 这样的数字代码适用于所有字符，包括我们符号键盘上的字符。

如果你的页面保存为 UTF-8（现代网站的默认设置），也可以直接粘贴符号本身。在邮件模板、会过滤特殊字符的 CMS 字段中，或希望源码保持纯 ASCII 时，代码依然很有用。要查找任意字符的代码，请使用 Unicode 查询。
