CSS Combinators

"CSS Combinators" is a crucial chapter that delves into the various combinators in CSS, offering a powerful way to select and style HTML elements based on their relationships in the document structure.

Basics of CSS Combinators

Descendant Selector

Selects all elements that are descendants of a specified element.

				
					.parent div {
  /* Styles applied to all div elements inside .parent */
}

Child Selector

Selects all direct children of a specified element.

				
					.parent > p {
  /* Styles applied to all p elements that are direct children of .parent */
}

General Sibling Selector

Selects all siblings that follow a specified element.

				
					.heading ~ p {
  /* Styles applied to all p elements following a .heading */
}

Advanced CSS Combinators

Universal Selector

Selects all elements, allowing you to apply styles globally.

				
					* {
  /* Styles applied to all elements on the page */
}

Attribute Selectors

Selects elements based on their attributes.

				
					input[type="text"] {
  /* Styles applied to text input elements */
}

:not() Pseudo-class

Selects elements that do not match a given selector.

				
					div:not(.exclude) {
  /* Styles applied to all div elements except those with class .exclude */
}

:nth-child() Pseudo-class

Selects elements based on their position in a parent.

				
					ul li:nth-child(odd) {
  /* Styles applied to odd-numbered list items in a ul */
}

Examples

Responsive Navigation

Apply styles to create a responsive navigation menu using combinators.

				
					.nav > ul {
  /* Styles applied to direct ul children of .nav */
}

.nav > ul > li {
  /* Styles applied to direct li children of ul inside .nav */
}

Form Styling

Style form elements selectively using combinators.

				
					form input[type="text"] {
  /* Styles applied to text input elements within a form */
}

form label + input {
  /* Styles applied to input elements immediately following a label within a form */
}
