Basic Structure of a CSS3 File

Section titled “Basic Structure of a CSS3 File”

A CSS file contains style rules that specify how HTML elements should be displayed. The basic structure of a CSS file includes:

  1. Selectors: Indicate which HTML elements the styles apply to.
  2. Properties: Define what aspects of the element’s style are being controlled.
  3. Values: Specify the settings for the properties.

Example:

/* This is a comment */
body {
    background-color: #f0f0f0;  /* Sets the background color of the body */
    font-family: Arial, sans-serif;  /* Sets the font family */
}


h1 {
    color: #333;  /* Sets the text color of h1 elements */
    text-align: center;  /* Centers the text */
}


p {
    line-height: 1.6;  /* Sets the line height for paragraphs */
    margin: 10px 0;  /* Sets the margin for paragraphs */
}

Creating Your First CSS3 File

Section titled “Creating Your First CSS3 File”

  1. Open your preferred text editor or IDE.

  2. Create a new file and name it styles.css. The .css extension indicates that this is a CSS file.

  3. Write some basic CSS rules. For example:

body {
    background-color: #e0e0e0;
    font-family: 'Helvetica Neue', Arial, sans-serif;
}


h1 {
    color: #2c3e50;
    text-align: center;
}


p {
    font-size: 16px;
    color: #34495e;
}

  1. Save the file in your project directory.

  2. Link the CSS file to your HTML file. Open your HTML file (e.g., index.html) and add a link to the CSS file in the <head> section:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>My First CSS Example</title>
    <link rel="stylesheet" href="styles.css">
</head>
<body>
    <h1>Hello, World!</h1>
    <p>This is my first CSS example.</p>
</body>
</html>
  1. Open your HTML file in a web browser to see the styles applied.

By following these steps, you set up a basic environment for writing and testing CSS3 code. As you gain more experience, you can explore more advanced tools and techniques to enhance your workflow and improve your CSS skills.
