Content images receive AI-generated descriptive alt text; decorative images (icons, spacers, toggles) receive alt="" per WCAG best practice. Also adds Image Descriptions section to the accessibility page, and fixes Pandoc Lua writers to output alt attributes. 67 files, covering help docs, news archive, ENCODE pages, portal pages, and session examples. refs #37254 diff --git src/hg/htdocs/goldenPath/help/trackSearch.html src/hg/htdocs/goldenPath/help/trackSearch.html index 7be7eda6a3b..65377de9436 100755 --- src/hg/htdocs/goldenPath/help/trackSearch.html +++ src/hg/htdocs/goldenPath/help/trackSearch.html @@ -47,37 +47,37 @@ information available about the terms.</p> <h2>Results</h2> <p> After clicking the "Search" button, the first 100 tracks that meet the search criteria are displayed.</p> <p> <strong>Check-box/Visibility: </strong> Tracks that are currently being displayed in the browser will have their check-box selected. To turn tracks on or off, select or deselect the associated check-box. To turn all tracks listed on the current results page on or off, click the "+" or "-" button at the top of the column. By default, selecting the check-box of a track turns the track to pack as long as pack is a valid view mode of the track. If it isn't, the track is set to full or show. Once the check-box of a track is selected, the visibility can be changed using the drop-down menu in the visibility column.</p> <p> -The <img class="gbsInlineImg" src="../../images/folderWrench.png" width="15" height="15"> icon +The <img alt="" class="gbsInlineImg" src="../../images/folderWrench.png" width="15" height="15"> icon designates "container tracks" that can be configured by clicking the icon. Container tracks don't have data themselves; instead, they contain other tracks that do have data. Examples of container tracks are composite tracks, which have a light orange background in the search results, and super-tracks, which have a tan background; tracks that contain data have a yellow background.

Please note, since container tracks don't have data of their own, turning one on via track search may result in no additional tracks in the browser. If this occurs, it is because none of the tracks within the container were turned on.</p> <p> <strong>Track information: </strong> To find out more information about a track, click on the Track Name. The description of the track or the container track will pop-up. Click "x" at the top of the pop-up or the "OK" at the bottom to close it. For tracks that have metadata, mainly ENCODE tracks at this time, there is a "..." link on the right-hand side of the track result row. Clicking this link expands the row to show the track's metadata.</p> <p> <strong>Sorting:</strong> By default, resulting tracks are listed in order of relevance.
