Font Size Access Keys Criterion

Make all fonts and widths and sizes scalable so the user can enlarge the page.

• Do not use fixed sizes - width or height - so users with low vision, small monitors or mobile devices can set preferences on their own machines.
• Internet Explorer does not provide a way for users to enlarge fixed fonts on their systems so avoid using fixed-widths such as "pt", "px".
• You should also design using percentages rather than set widths so that your layout renders correctly in any resolution.
• The spider will check for this by searching for fixed sizes in the code and the CSS such as px, pt and font size. Using any numbers in relation to the size of a column, cell or font without a "%" symbol or "em" will cause a deduction.
• Points - Awarded by percentage of compliance (t=3p).
• Criterion weighting of two.
