Typography & Styling Text in CSS

Typography is one of the most important aspects of web design. It’s not just about choosing pretty fonts—it’s about creating a readable, accessible, and visually appealing experience for your users. In this blog, we’ll explore three key areas of CSS typography: choosing and styling fonts, the power of variable fonts, and improving readability with line height and letter spacing.

1. CSS Typography: Choosing and Styling Fonts for Better Readability

Choosing the Right Font

The first step in good typography is selecting the right font. Here are some tips:

Serif vs. Sans-Serif: Serif fonts (e.g., Times New Roman) are often used for print and formal content, while sans-serif fonts (e.g., Arial) are cleaner and more modern, making them ideal for digital screens.
Web-Safe Fonts: Use web-safe fonts like Arial, Georgia, or Verdana to ensure consistency across devices.
Google Fonts: For more variety, use Google Fonts, which offers hundreds of free, web-optimized fonts.

Styling Fonts in CSS

Once you’ve chosen a font, you can style it using CSS properties like font-family, font-size, font-weight, and font-style.

body {
    font-family: 'Roboto', sans-serif;
    font-size: 16px;
    font-weight: 400; /* Normal weight */
    font-style: normal;
}

Improving Readability

Font Size: Use a base font size of 16px for body text and adjust headings proportionally.
Contrast: Ensure sufficient contrast between text and background colors.
Line Length: Keep lines of text between 50-75 characters for optimal readability.

2. The Power of Variable Fonts in CSS

What Are Variable Fonts?

Variable fonts are a game-changer in web typography. Unlike traditional fonts, which come in fixed weights and styles (e.g., regular, bold, italic), variable fonts allow you to customize weight, width, slant, and other attributes dynamically using CSS.

Benefits of Variable Fonts

Flexibility: Adjust font properties on the fly without loading multiple font files.
Performance: Reduce the number of HTTP requests, improving page load times.
Creative Freedom: Experiment with unique typography styles.

Using Variable Fonts in CSS

To use a variable font, first load it from a service like Google Fonts or Adobe Fonts. Then, customize its properties using the font-variation-settings property.

@import url('https://fonts.googleapis.com/css2?family=Roboto+Flex:wght@100..900&display=swap');

body {
    font-family: 'Roboto Flex', sans-serif;
    font-variation-settings: 'wght' 400, 'wdth' 100;
}

h1 {
    font-variation-settings: 'wght' 700, 'wdth' 120;
}

3. Line Height, Letter Spacing, and Readability in CSS

Line Height

Line height (line-height) is the vertical space between lines of text. Proper line height improves readability by preventing text from feeling cramped or too spaced out.

p {
    line-height: 1.6; /* A good rule of thumb is 1.5 to 1.6 for body text */
}

Letter Spacing

Letter spacing (letter-spacing) adjusts the space between characters. It’s particularly useful for headings or uppercase text to improve legibility.

h1 {
    letter-spacing: 1px; /* Slightly increase spacing for headings */
}

.uppercase {
    letter-spacing: 2px; /* More spacing for uppercase text */
}

Combining Line Height and Letter Spacing

Here’s an example of how to combine these properties for better readability:

body {
    font-family: 'Open Sans', sans-serif;
    font-size: 16px;
    line-height: 1.6;
    letter-spacing: 0.5px;
}

Putting It All Together

Here’s an example of a CSS snippet that incorporates all the concepts we’ve discussed:

@import url('https://fonts.googleapis.com/css2?family=Roboto+Flex:wght@100..900&display=swap');

body {
    font-family: 'Roboto Flex', sans-serif;
    font-size: 16px;
    font-variation-settings: 'wght' 400, 'wdth' 100;
    line-height: 1.6;
    letter-spacing: 0.5px;
    color: #333;
}

h1 {
    font-variation-settings: 'wght' 700, 'wdth' 120;
    font-size: 2.5rem;
    letter-spacing: 1px;
}

p {
    margin-bottom: 1.5em;
}

Conclusion

Typography is a powerful tool in web design, and mastering it can significantly enhance the user experience. By choosing the right fonts, leveraging variable fonts, and fine-tuning line height and letter spacing, you can create websites that are not only beautiful but also highly readable and accessible.
