What are CSS selectors?

CSS selectors are used to match and select elements in HTML documents. They allow us to apply styles to specific HTML elements, thereby controlling their visual presentation.

Type of selector:

• Universal selector (*): Matches all elements.
• Element selector (tag): Matches elements with specific tag names. For example, p matches all paragraph elements.
• ID Selector (#): Matches elements with a specific id attribute value. For example, #my-id matches elements with the id "my-id".
• Class selector (.): Matches elements with a specific class attribute value. For example, .my-class matches all elements with the class name "my-class".
• Descendant selector (space): Matches elements whose parent element has a specific selector. For example, p span matches all span elements whose parent element is a paragraph element.
• Child element selector (>): Matches elements whose immediate parent element has a specific selector. For example, div > p matches all div elements whose direct children are paragraph elements.
• Adjacent Selector ( ): Matches elements that have a specific selector immediately before the element. For example, p span matches any span element immediately following a paragraph element.

Usage:

Selectors are used in CSS style sheets to select elements to which styles should be applied. The syntax is as follows:

selector {
  property: value;
}

For example, the following style sets the text color of all paragraph elements to blue:

p {
  color: blue;
}
