See Understanding Techniques for WCAG Success Criteria for important information about the usage of these informative techniques and how they relate to the normative WCAG 2.0 success criteria. The Applicability section explains the scope of the technique, and the presence of techniques for a specific technology does not imply that the technology can be used in all situations to create content that meets WCAG 2.0.
All technologies that support CSS.
This technique relates to:
Note: This technique must be combined with other techniques to meet SC 1.3.2. See Understanding SC 1.3.2 for details.
The objective of this technique is to demonstrate how the visual appearance of spacing in text may be enhanced via style sheets while still maintaining meaningful text sequencing. The CSS letter-spacing property helps developers control the amount of white space between characters. This is recommended over adding blank characters to control the spacing, since the blank characters can change the meaning and pronunciation of the word.
The following CSS would add the equivalent of a space between each character in a level-2 heading:
Example Code:
h2 { letter-spacing: 1em; }So for the markup:
Example Code:
<h2>Museum</h2>
the rendered result might look something like:
Example Code:
M u s e u m

For each word that appears to have non-standard spacing between characters:
Check whether the CSS letter-spacing property was used to control spacing.
Check #1 is true.
If this is a sufficient technique for a success criterion, failing this test procedure does not necessarily mean that the success criterion has not been satisfied in some other way, only that this technique has not been successfully implemented and can not be used to claim conformance.
