Frequently Asked Questions
What is a CSS font stack?
A font stack is an ordered list of fonts in the font-family property. The browser tries each font in order and uses the first one available on the device.
Why put sans-serif at the end?
Generic families like sans-serif act as a guaranteed last resort, so text still renders even if every named font is missing.
What is system-ui?
system-ui matches the operating system font: SF Pro on Apple platforms, Segoe UI on Windows, and Roboto on Android. It renders instantly with no download.
Which stack is best for Thai text?
Use a stack that starts with Thai-native fonts such as IBM Plex Sans Thai, Sarabun, or Noto Sans Thai, followed by Tahoma and sans-serif as fallbacks.
