text-size-adjust | CSS CSS Properties

Mainly used for mobile devices, this property tells the browser whether it should automatically increase the size of text to make it more readable when you rotate your phone or zoom in. Setting it to 'none' prevents this behavior.

Quick example

html {
  /* Prevents iOS Safari from automatically resizing text when rotating from portrait to landscape */
  text-size-adjust: none;
}
