p.class-name和p[class=class-name]都是用来选择HTML文档中具有特定class属性值的p元素的CSS选择器。
区别在于:
- p.class-name是通过类选择器来选择具有指定class属性值的p元素。它会选择所有class属性值中包含指定class-name的p元素。例如,p.class-name会选择所有class属性值中包含"class-name"的p元素,如<p class="class-name">。
- p[class=class-name]是通过属性选择器来选择具有指定class属性值的p元素。它会选择class属性值完全等于指定class-name的p元素。例如,p[class=class-name]会选择class属性值为"class-name"的p元素,如<p class="class-name">。
