Types of Advanced CSS Selectors

Example
div p selects all paragraph elements inside a div
Child Selector
This selector targets only direct children of an element
Example
div greater than p selects only direct paragraph children of a div
Adjacent Sibling Selector
This selector targets an element immediately following another element
Example
h1 plus p selects the first paragraph that comes right after an h1
General Sibling Selector
This selector targets all siblings that come after a specified element
Example
h1 tilde p selects all paragraphs after an h1
Attribute Selectors
These selectors target elements based on their attributes
Example
input type equals text targets input fields with type text
Pseudo Classes
Pseudo classes define a special state of an element
Common examples include hover active focus and nth child
Example

Pseudo Elements
Pseudo elements style specific parts of an element
Examples include first letter first line before and after
Example
p first letter styles the first letter of a paragraph

This selector targets elements based on their position
Example
li nth child 2 selects the second list item
Not Selector
This selector excludes specific elements
Example
p not class name selects all paragraphs except those with a specific class
Best Practices
