    How does the font-display property improve perceived performance?
    font-display is an attribute of @font-face in CSS, which is used to control the display behavior when custom fonts are loaded.

Fallback values ??provide a balance between quick display and restricted delayed replacement; 3. Avoid using blocks to reduce text hiding; 4.
