Accessibility Checkpoint WCAG 1 3.4


Use relative rather than absolute units in HTML attributes.


Use percentages rather than pixels for sizing frames and tables. Low-vision users often use the «large fonts» mode of Windows, which makes each pixel larger than usual. This usually causes problems with pixel based layouts, which also perform badly on handheld and widescreen displays. Percentage values «stretch» according to screen size and work on a large range of display sizes.
