Targeting Specific Classes in CSS: A Definitive Guide

Specific Class Selector (tag.classname)

A Specific Class Selector in CSS combines both an HTML element type (tag) and a class name to target and apply styles to specific HTML elements that share the same class attribute. This selector is used when you want to target elements of a particular type that also have a specific class applied to them. It provides a way to style a subset of elements that meet both criteria.

Syntax: The syntax for a Specific Class Selector is as follows:

tag.classname {
  /* 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>Specific Class Selector</title>
    <style>
      .color {
        color: goldenrod;
      }
      h1.color {
        text-decoration: underline;
        text-transform: uppercase;
      }
      .a {
        color: blue;
      }
      li.color {
        color: brown;
      }
    </style>
  </head>
  <body>
    <h1 class="color">Specific Class Selector</h1>

      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.
