When it comes to selectors, I only know that class selection conforms to the ID selector, but I am not very clear about the priority of the selector. Below, excerpt from the example in the book:

Set the !important keyword statement on the attribute to increase the weight of the attribute. Properties declared with the !important keyword have the highest priority.

  • Tag selectors, pseudo-classes and pseudo-objects: the priority score is 1.
  • Class selector, attribute selector: Priority level points are 10.
  • ID selector: Priority level points are 100.
  • style attribute: Priority points are 1000.
  • Example:

    p{ color:blue; }

    p .myColor{color:black;}

    .myColor{color:yellow;}

    #myColor{color:red;}

    p=1

    p .myColor=1 10=11

    .myColor=10

    #myColor=100

    style="color:green;"=1000

    The color labeling part is easy to make mistakes. I always thought that the color of the second label had a higher priority. .
