CSS Tutorial

CSS (Cascading Style Sheets) is a design language used to enhance the appearance of web pages. It allows developers to control the layout, colors, typography, and other visual aspects of a document written in HTML or other markup languages. Think of CSS as the "styling" part of a webpage, much like the skin tone or eye color of a human body.

What is CSS?

CSS stands for Cascading Style Sheets. It simplifies the process of designing web pages by allowing developers to specify how HTML elements should be displayed. For example, CSS can change the font color, size, or layout of a webpage effortlessly.

Who Should Learn CSS?

This CSS tutorial is ideal for aspiring web designers and developers. Basic CSS knowledge is essential for anyone aiming to become a professional web developer, even if you plan to use frameworks like Bootstrap or Tailwind CSS.

Types of CSS Usage

CSS can be applied to an HTML document in three main ways:

  • Inline CSS: Applied directly to HTML elements using the style attribute. It has the highest priority.
  • Internal CSS: Defined within a <style> tag in the <head> section of the document.
  • External CSS: Stored in a separate file and linked to the HTML document using the <link> tag. This method is recommended for projects as it allows easy maintenance and reuse.

Example of CSS Usage:

The example below demonstrates all three types of CSS:

HTML

  <!DOCTYPE html>
  <html>
  <head>
  <title>CSS Tutorial</title>
    
    <style>
        h1 {
            color: blue;
        }
    </style>
    
    <link rel="stylesheet" href="styles.css">
</head>
<body>
  <h1>Welcome to CSS
  <p style="font-weight: bold; color: red;">This is an example of inline CSS.

</body> </html>

External CSS File (styles.css):

HTML

body {
    font-family: Arial, sans-serif;
    margin: 20px;
}
