What is CSS selectors? Name some.

CSS selectors are patterns used to select specific HTML elements on a web page. Selectors determine which elements the CSS rules will apply to. Here are some commonly used CSS selectors:

  1. Type Selector: Selects elements based on their tag name. For example, h1 selects all <h1> elements.
  2. Class Selector: Selects elements based on their class attribute value. It is denoted by a dot (.) followed by the class name. For example, .container selects all elements with the class “container”.
  3. ID Selector: Selects elements based on their ID attribute value. It is denoted by a hash (#) followed by the ID name. For example, #my-element selects the element with the ID “my-element”.
  4. Attribute Selector: Selects elements based on their attribute values. It can select elements with specific attribute values or attribute presence. For example, [type="text"] selects all elements with type="text" attribute.
  5. Descendant Selector: Selects elements that are descendants of another element. It uses whitespace to separate the parent and descendant elements. For example, div p selects all <p> elements that are descendants of a <div> element.
  6. Child Selector: Selects elements that are direct children of another element. It uses the > symbol to separate the parent and child elements. For example, ul > li selects all <li> elements that are direct children of a <ul> element.
  7. Adjacent Sibling Selector: Selects an element that comes immediately after another element. It uses the + symbol to select the adjacent sibling. For example, h2 + p selects the <p> element that comes immediately after an <h2> element.
  8. General Sibling Selector: Selects elements that are siblings of another element. It uses the ~ symbol to select the siblings. For example, h2 ~ p selects all <p> elements that are siblings of an <h2> element.

These are just a few examples of CSS selectors. CSS provides a wide range of selectors, including pseudo-classes, pseudo-elements, combinators, and more, allowing you to target elements based on various criteria and create precise styling rules.
