The priority of the selector in CSS (※about overwriting of the same attribute)

<Style> # A {color: Red }. B {color: Blue; fontsize: 20px} </style> <Div id = "A" Class = "B"> test </div>

 

--------------------------------------------

Dest

The font size is 20 defined in [class selector], and the color is red in [ID selector ].

 

The ID level is greater than the class

Before ID is #

Before the class is.

 

※※※Note ※※※

The overwrite does not mean that the content in the class is no longer used with the ID.

The same as [Class] in [ID] will overwrite. Different parts will also use the attributes defined in [class selector.
