Mastering CSS Fonts: A Comprehensive Guide

CSS (Cascading Style Sheets) is essential for controlling the font styles of your website. Understanding how to effectively use fonts can greatly enhance the visual appeal and readability of your content.

Key Concepts of CSS Fonts

1. Font Families

• Definition: A font family is a group of fonts that share similar characteristics.
• Examples:
  • serif: Fonts with small lines at the ends of characters (e.g., Times New Roman).
  • sans-serif: Fonts without the small lines (e.g., Arial).
  • monospace: Fonts where each character takes up the same amount of space (e.g., Courier).

Usage:

body {
    font-family: 'Arial', sans-serif;
}

2. Font Size

• Definition: Controls the size of the text.
• Units: Can be defined in various units like pixels (px), ems, rems, or percentages.

Usage:

p {
    font-size: 16px;  /* 16 pixels */
}

3. Font Weight

• Definition: Specifies the thickness of the text.
• Values: Can be defined as normal, bold, bolder, lighter, or numeric values (100 to 900).

Usage:

h1 {
    font-weight: bold;
}

4. Font Style

• Definition: Defines the style of the font, commonly used to make text italicized or normal.

Usage:

em {
    font-style: italic;
}

5. Text Transform

• Definition: Changes the case of the text.
• Values: uppercase, lowercase, capitalize, or none.

Usage:

h2 {
    text-transform: uppercase;
}

6. Line Height

• Definition: Controls the space between lines of text, enhancing readability.

Usage:

p {
    line-height: 1.5;  /* 1.5 times the font size */
}
