Final answer:
The CSS3 font-stretch property adjusts the width of text, making it narrower or wider for readability and design purposes.
Step-by-step explanation:
The CSS3 font-stretch property allows you to make text narrower (condensed) or wider (expanded) than the normal text. This property takes values such as 'condensed', 'expanded', 'normal', and specific percentage values to control the width of the text. For example, setting font-stretch to 'expanded' will make the font wider, and 'condensed' will make it narrower. This is particularly useful when you want to adjust the text appearance for better readability, aesthetic purpose, or space management without changing the font size.
