Filter Description
[attribute] Matches elements that have the specified attribute.
[!attribute] Matches elements that don't have the specified attribute.
[attribute=value] Matches elements that have the specified attribute with a certain value.
[attribute!=value] Matches elements that don't have the specified attribute with a certain value.
[attribute^=value] Matches elements that have the specified attribute and it starts with a certain value. 屬性值的 起始 爲特定的值
[attribute$=value] Matches elements that have the specified attribute and it ends with a certain value.
屬性值的 結束 爲特定的值
[attribute*=value] Matches elements that have the specified attribute and it contains a certain value.
屬性值的 包含 特定的值
