在附加 CSS 属性 之前加一个点的目的是什么？
What is the purpose of a dot before an additional CSS property?
这是我在代码中的内容：
min-height: 35px;
.min-height: 25px;
}
第二行是做什么的？我假设它用于跨浏览器样式目的，但不确定是哪个。
我猜它的目标是 IL 6 和 7，尽管通常使用 _ 或 -。
Due to a parsing error, Internet Explorer 6 and below wouldn't fail on
properties that were prefixed with non-alphanumeric characters.
和
Although Internet Explorer 7 corrected its behavior when a property
name is prefixed with an underscore or a hyphen, other
non-alphanumeric character prefixes are treated as they were in IE6.
Therefore, if you add a non-alphanumeric character such as an asterisk
(*) immediately before a property name, the property will be applied
in IE and not in other browsers.
