Today we will tell you about the use of the property selector and pseudo-class selector and related links and differences, let's give you a small example.

Property selector:

[attr~= "value"] word word space word Word must value valid

[attr|= "value"] value beginning or value-word

Attention:

The choice of attributes is very difficult to judge the selection element by the regular expression, the efficiency is higher

Pseudo-Class selectors:

: Before

: After

: Lang (val) val/val-words

: Nth-child (N) n calculates the odd cardinality even the even number starting from 1

: the Nth-of-type (n) selector matches each element of the nth child element of a particular type that belongs to the parent element.
