1.css Selector

Sub-selector: parent>child

A child selector refers to the first child element in the range that selects the parent. Both parent and child are pseudo-code here. Can be a class with a. classname, or it can be a label ul>li, or an ID #pid > #cid

Descendant selector: Parent Child

Descendant selectors are: Select the desired child element within the parent range. Unlike a child selector, this contains child elements that are nested inside, whereas a sub-selector selects only the first child element directly under the parent.

Global selection: *{}

This allows you to configure the global default configuration, such as removing the default spacing.

Multiple selectors set simultaneously: h,span,div{}

Multiple selectors set a common style with a comma interval.
