Unlocking the Versatility of Class Selectors in CSS: A Practical Guide

Class Selector (.)

A Class Selector in CSS is used to target and apply styles to one or more HTML elements that share the same class attribute. Class selectors are preceded by a dot (.) followed by the class name. They provide a way to apply styles to specific groups of elements in a more targeted and reusable manner.

Syntax: The syntax for a class selector is as follows:

.class-name {
  /* CSS styles go here */
}

Source Code :

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>Class Selector</title>
    <style>
      .color {
        color: goldenrod;
      }
    </style>
  </head>
  <body>
    <h1 class="color">Class Selector</h1>
    <p>
      HTML elements or tags represent different parts of a web page's structure and content, such as <b class="color"> headings, paragraphs</b>, lists, images, links, and more. XML tags serve a similar purpose but can be customized to define the structure of data within an XML document according to
      a specific schema.
    </p>

    <ul>
      <li>HTML</li>
      <li class="color">CSS</li>
      <li>JavaScript</li>
    </ul>
  </body>
</html>

The provided CSS code .color { color: goldenrod; } defines a class selector and specifies styles for elements with the class attribute set to "color."

Class selectors are a powerful tool for styling web pages because they provide a way to apply styles selectively to specific elements or groups of elements. They are particularly useful for creating consistent and modular styles in your CSS code.
