<p>CSS Selector Type

<p>CSS selectors are used to specify HTML elements or groups of elements to apply styles to them . There are four main types of CSS selectors:

<p>1. Basic selectors

<p>Basic selectors select elements by name, including:

  • Element selector: Select elements with specific HTML tags, such as <p>, <h1>
  • Class selector: Select elements with specific class attributes, such as .primary, .container
  • ID selector: Select elements with a specific ID attribute, such as #main, #contact
<p>2. Modifier selector

<p>Modifier selectors are used to refine the selection range of the basic selector, including:

  • Descendant selector (blank): Select elements that are descendants of the parent element, such as div p
  • Child selector (>): Select elements that directly belong to the parent element, such as div > p
  • Adjacent selector ( ): Select the element immediately adjacent to the previous element, such as p h1
  • Pseudo-class selector (:hover, :active): Select elements in a specific state, such as when the mouse is hovering (:hover), or when activated (:active)
<p>3. Attribute selector

<p>Attribute selector selects elements according to their attribute values, including:

  • Attribute existence selector ([ Attribute]): Select elements with specific attributes, such as [type]
  • Attribute value selector ([attribute="value"]): Select elements with specific attribute values, such as [type="text"]
  • Partial matching attribute value selector ([attribute~="value"]): Select elements whose attribute values ​​contain the specified substring, such as [type~="text"]
<p>4. Combination selector

<p>Combined selectors allow multiple selectors to be combined together, for example:

  • Group selector (brackets): Group multiple selectors and apply the same group of styles, such as (p , h1) { ... }
