How Can We Ensure Consistent Font Sizing Across Varying Screen Resolutions?

Font Size Relative to Screen Resolution

Fluidity in website design is paramount, but ensuring proper font sizing across varying resolutions can be a challenge. The issue is that browser's font size can override units like "em," leaving menu text wrapping outside the designated box.

Solution: Viewport Relative Units

Modern CSS introduces viewport relative units that account for device screen resolution:

• vw (Viewport Width Percentage): Represents a percentage of the viewport width.
• vh (Viewport Height Percentage): Percentage of the viewport height.
• vmin (Viewport Minimum Value): Smaller of vw or vh.
• vmax (Viewport Maximum Value): Larger of vw or vh.

For example:

body {
    font-size: 3.2vw;
}

This sets the font size to 3.2% of the viewport width, ensuring it scales correctly for different screen resolutions.

Alternative Approaches

• Media Queries: Breakpoints can be defined using media queries, allowing font sizes to be adjusted for specific screen width ranges.
• Percent (%) and Root Ems (rem): By setting the base font size and using these units, text becomes scalable across devices and for accessibility.
