An example of an AI chatbot conversation about font size units in CSS.
What are the different units for font size in CSS?
In CSS, you can use several units for font size, including pixels (px), ems (em), rems (rem), percentages (%), and points (pt). Each has its own use cases.
Can you explain the difference between em and rem?
Sure! 'em' is relative to the font size of its nearest parent element, while 'rem' is relative to the root element's font size. This makes 'rem' more predictable for layout.
When should I use percentages for font size?
Percentages are useful for responsive design, as they allow font sizes to scale relative to the parent element's size, making your layout more flexible.
Are there any best practices for choosing font size units?
Yes! It's often recommended to use 'rem' for consistent sizing across your site, and 'em' for local adjustments. Avoid using fixed sizes like 'px' for better responsiveness.
