CSS选择器优先级最高的是什么?

在CSS中,选择器优先级决定了哪些样式规则将被应用到元素上。优先级最高的规则将覆盖优先级较低的规则。

CSS选择器优先级的最高级别是:

内联样式

内联样式直接写在HTML元素的style属性中。由于它们最直接地应用于元素,因此具有最高的优先级。

例如:

<p style="color: red;">这是红色文本。</p>
Copy after login

ID选择器

ID选择器使用元素的ID属性来选择元素。ID属性唯一标识每个元素,因此ID选择器具有非常高的优先级。

例如:

#my-element {
  color: blue;
}
Copy after login

类选择器

类选择器使用元素的class属性来选择元素。类属性可以应用于多个元素,因此类选择器的优先级低于ID选择器。

例如:

.my-class {
  color: green;
}
Copy after login

元素选择器

元素选择器选择特定类型的元素,例如p、h1或div。元素选择器的优先级低于类选择器。

例如:

p {
  color: black;
}
Copy after login

通配符选择器

通配符选择器(*)选择文档中的所有元素。其优先级最低。

例如:

* {
  font-size: 12px;
}
Copy after login

如果多个选择器具有相同的优先级,则将使用最后声明的规则。遵循上述优先级顺序,可以确保特定元素的样式应用正确的规则。
