| <p class="note">These are DRAFT notes on what CSS classes, PHP functions and the so on have been added to Moodle 1.6 onwards to aid accessibility. They can be seen as design patterns, techniques, guidelines, and perhaps best practice(?)

| Based on a workshop at [http://moodlemoot.ca Moodlemoot 2007, Canada]
| | This page has been replaced because the content was no longer applicable to the current version of Moodle. |
| Lots for me to add/edit! Comments welcome!

|
| == Code pattern 1: unlist & inline-list ==
| | The previous version of this document can be seen [https://docs.moodle.org/dev/index.php?title=Accessibility_notes&oldid=49247 in the history] |
| Cascading style sheet (CSS) classes to remove default list-styles from HTML lists.
| |
| Class <code>inline-list</code> also makes a list horizontal (at present only in side blocks).
| |
| | |
| Difficulty: '''easy''' I hope. Please use!<br />
| |
| Available: ? Moodle 1.8 December 2006 (MDL-6838, nested lists are safe).<br />
| |
| Definition: <code>theme/standard/styles_layout.css</code>
| |
| .unlist, .inline-list {
| |
| list-style: none;
| |
| padding: 0;
| |
| margin: 0;
| |
| }
| |
| .sideblock .content .inline-list li {
| |
| display: inline;
| |
| }
| |
| | |
| Use Count: 5+ (12 including deprecated <code>list</code>)<br />
| |
| Example: <code>blocks/../block_blog_tags.php</code>
| |
| <nowiki><ul class="inline-list">
| |
| <li><a .. class=" s20">Accessibility</a></li>
| |
| <li><a .. class=" s10">Test</a></li>
| |
| </ul></nowiki>
| |
| | |
| | |
| == Code pattern 2: accesshide ==
| |
| CSS class for text to be 'seen' by screen readers but not visual users.
| |
| | |
| Text classed as <code>accesshide</code> provides context for a non-sighted user, where the context or meaning would otherwise be clear from formatting, for example coloured text, or a ''silent'' character (TODO: link). The example below shows how additional text is provided to differentiate ''today'' from the other days in the Moodle calendar - visual differentiation is provided in the ''standard'' theme by a black border, and the <code>accesshide</code> text is duplicated, in this case using Javascript (TODO: modify code! Javascript should use the title attribute.)
| |
| | |
| Please, use cautiously — most necessary uses have already been identified.
| |
| | |
| * Difficulty: '''tricky''' — please put the same text in an adjacent/parent <code>title</code>.
| |
| * Available: Moodle 1.6 March 2006 (30-May-06: MDL-5628 <acronym title="Internet Explorer">IE</acronym>6 Farsi <acronym title="Right-to-left">RTL </acronym>language)
| |
| * Definition: <code>theme/standard/styles_layout.css</code>
| |
| .accesshide {
| |
| position: absolute;
| |
| top: -1000px;
| |
| }
| |
| | |
| * Use Count: 29 !<br />
| |
| * Example: <code>calendar/lib.php</code>
| |
| <nowiki>...
| |
| <td class="day">26</td>
| |
| <td class="day today">
| |
| <span class="accesshide">Today Friday, 27 April </span>
| |
| <a onmouseover="return overlib(.. 'Today Friday, 27 April')" ..>27</a>
| |
| </td>
| |
| <td class="weekend day">28</td>
| |
| ...</nowiki>
| |
| | |
| == Code pattern 3: THEME->rarrow, larrow ==
| |
| | |
| PHP variables holding 'silent' representations of right and left arrows (example ►), to avoid misuse of characters including "greater than" >, "right angle quote" ». The variables are initialised by the function weblib.php: check_theme_arrows, unless they have first been defined in the theme config.php.
| |
| | |
| * Difficulty: medium. Careful with fonts.<br />
| |
| * Available: Moodle 1.7
| |
| * Associated CSS in theme/standard/styles_fonts.css
| |
| | |
| .breadcrumb .sep, ... {
| |
| font-family: Arial,Helvetica,Courier,'Arial Unicode MS', ...;
| |
| }
| |
| | |
| * Use count: ?
| |
| * Example PHP: weblib.php function print_navigation - breadcrumb trail.
| |
| * Also: Weekscss course format, Moodleforms .
