The[attribute^="value"]selector is used to select elements whose attribute value begins with a specified value. The following example selects all elements with a class attribute value that begins with "top": Note:The value does not have to be a whole word!
:not(selector):选中不匹配给定选择器的元素。例如,div:not(.active)选中所有没有.active类的<div>元素。特殊状态选择器::empty:选中没有任何子元素(包括文本节点)的元素。:target:选中URL中指定id的元素。例如,如果URL是http://example.com/#section1,则:target会选中id为section1的元素。
