Here are some commonly used CSS properties that are generally safe for email:
- Font-family: Use web-safe fonts like Arial, Helvetica, and Verdana. - Font-size: Use relative units like em or percentages for scalability. - Color: Hex codes and RGB values are widely supported. - Background-color: This property is generally safe but avoid using background images as they are not universally supported. - Padding and Margin: Use these properties for spacing elements, but test across different clients for consistency. - Border: Simple borders are usually safe, but avoid complex styles.
