Add some beautiful styles to your element based on the user's event on elements like hovering, focusing an element, etc. Pseudo Classes are mainly used to add some modification in styles of your element based on the state of your element.
Pseudo-classes are mainly used to apply styles to your selectors, based on the fulfillment of a specific condition, following are some of the pseudo-classes which designers use most of the time.
a:hover
: Most commonly used pseudo-class that designers use with their selectors in HTML.:hover
this pseudo-class is mainly used to define the behavior of your selector when the user hovers the mouse on that element.a:hover { cursor: grab; color: #f76c6c; background-color: black; }
a:visited
: All the effects inside this visited pseudo-class will be applied to this a tag after a user is visited the anchor tag once.a:visited { color: aqua; font-family: sans-serif; }
input:disabled
: This pseudo-class is applied when our input element is in a disabled state. Check out the below example for the reference of this pseudo-class.input:disabled { color: black; opacity: 0.9; }
.table-row:nth-child()
: This pseudo-class mainly used to target the entered value in the nth-child() brackets. Its value can be even, odd, or any specific value or formula as well.
The basic example we see is with data table-rows :nth-child(even)
in order to apply styles on an even number of rows i.e. 2, 4, 6 siblings in the sequence

}
