The “Layout Measurement Value Check” evaluates whether all layout-related measurement units (e.g., for width, padding, font size) are defined using relative units such as % and em.
Example outcome
I found all instances where the measurement units that define the width of content elements are expressed in relative values.
Impact
Visual Impairments: Zooming may cause text to overflow or become clipped.
Motor Impairments: Individuals with motor imairments may need to resize the interface for ease of interaction, and fixed sizes prevent that.
Cognitive Disabilities: Layout issues from fixed sizes create distractions or confusion.
Color Blindness: Users may zoom to compensate color blindness, but absolute units break layout scaling.
Elderly: Poor text scaling breaks page layout.
Fixes
To address inappropriate layout measurements defined using absolute units:
Locate the inappropriate measurement definition.
Replace the absolute unit by a relative one (e.g., em, rem and %).
