A graphical symbol may be an image, an image of text or a pictorial or decorative character symbol (glyph) which imparts information nonverbally. Examples of graphical symbols include an image of a red circle with a line through it, a "smiley" face, or a glyph which represents a check mark, arrow, or other symbol but is not the character with that meaning. Assistive technology users may have difficulty determining the meaning of the graphical symbol. If a graphical symbol is used to convey information, provide an alternative using features of the technology or use a different mechanism that can be marked with an alternative to represent the graphical symbol. For example, an image with a text alternative can be used instead of the glyph. </p></div><h2 class="small-head" id="F26-examples">Examples</h2><div class="failure"><h3 class="small-head" id="F26-failex1"> Failure Example 1: Glyphs Used to Indicate Status</h3><div class="example"><div class="textbody"><p> A shopping cart uses two simple glyphs to indicate whether an item is available for immediate shipment. A check mark indicates that the item is in stock and ready to ship. An "x" mark indicates that the item is currently on back order and not available for immediate shipment. An assistive technology user could not determine the status of the current item. </p></div></div></div><h2 id="F26-resources">Resources</h2><div class="textbody"><p>No resources available for this technique.</p></div><h2 id="F26-related-techs">Related Techniques</h2><div class="textbody"><ul><li><a href="H37.html">H37: Using alt attributes on img elements</a></li></ul></div><h2 id="F26-tests">Tests</h2><div class="textbody"><h3 class="small-head" id="F26-procedure">Procedure</h3><ol class="enumar"><li><p>Examine the page for non-text marks that convey information. </p></li><li><p>Check whether there are other means to determine the information conveyed by the non-text marks.</p></li></ol><h3 class="small-head" id="F26-results">Expected Results</h3><ul><li><p>If step #2 is false, then this failure condition applies and the content fails this Success Criterion.</p></li></ul></div><!-- BOTTOM NAVIGATION BAR --><ul id="navigationbottom"><li><strong><a href="#top">Top</a></strong></li><li><strong><a href="Overview.html#contents" title="Table of Contents">Contents</a></strong></li><li><strong><a href="intro.html" title="Introduction to Techniques for WCAG 2.0"><abbr title="Introduction">Intro</abbr></a></strong></li><li><a title="F25: Failure of Success Criterion 2.4.2 due to the title of a Web page not identifying the&#xA; contents" href="F25.html"><strong>Previous: </strong>Failure F25</a></li><li><a title="F30: Failure of Success Criterion 1.1.1 and 1.2.1 due to using text alternatives that are not&#xA; alternatives (e.g., filenames or placeholder text)" href="F30.html"><strong>Next: </strong>Failure F30</a></li></ul><div class="footer"><p class="copyright">This Web page is part of <a href="Overview.html">Techniques and Failures for Web Content Accessibility Guidelines 2.0</a> (see the <a href="https://www.w3.org/TR/WCAG20-TECHS/F26.html">latest version of this document</a>).
