Final answer:
The user's browser selects the actual font used when only the font-family attribute is specified, choosing from the fonts available on the user's computer or device.
Step-by-step explanation:
When only the font-family attribute is provided in a document, the actual font that is displayed is picked by the user's browser based on the fonts available on the user's computer or device.
If the specified font is not available, the browser will fall back to a default font, which can be a generic family specified in the CSS (like 'serif', 'sans-serif', etc.), or a browser-specific default font. The ability to choose from such a vast range of digital typefaces allows designers to create a unique typography that conveys the appropriate theme and personality for each corporate identity. For example, a strong and reliable typeface might be chosen for an oil and gas company, while a soft and friendly font could be more suitable for a baby food brand.
