FAQs
1. What is the best way to choose a font for my website?
Consider your brand personality, the audience you are targeting, and the readability of the font. Always test it in various sizes and contexts.
2. Can I use custom fonts on my website?
Yes! You can use custom fonts by importing them via CSS using @font-face or using web font services like Google Fonts or Adobe Fonts.
3. What is the difference between px, em, and rem?
px is a fixed unit, while em and rem are relative units. em is relative to the font-size of the parent element, and rem is relative to the root element’s font-size. This makes em and rem more flexible for responsive design.
4. How do line-height and font-size work together?
Line-height determines the space between lines of text, and when combined with font-size, it influences the readability and overall layout. It’s recommended to set line-height to about 1.5 times the font-size for better readability.
5. Why should I provide fallback fonts?
Fallback fonts ensure that if the preferred font is not available on the user’s system, an alternative will be used, maintaining the design’s integrity and readability.
