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/indexIntro.html src/hg/htdocs/indexIntro.html index 39700ef82b3..436f28aa9f6 100644 --- src/hg/htdocs/indexIntro.html +++ src/hg/htdocs/indexIntro.html @@ -1,114 +1,113 @@ <!-- Introduction ============================================ --> <TABLE style="background-color:#888888; width: 100%; border-width: 0px; border-spacing: 0px; padding: 0px"> <TR><TD> <TABLE style="background-color:#fffee8; width: 100%; border-width: 0px; border-spacing: 0px; padding: 0px"> <TR><TD> <TABLE style="background-color:#D9E4F8; background-image: url('images/hr.gif'); width: 100%;"><TR><TD> <A NAME="About"></A><FONT SIZE="4"><B> About the UCSC Genome Bioinformatics Site</B></FONT> </TD></TR></TABLE> <TABLE style="background-color:#fffee8; width: 100%; padding: 0px"><TR><TD> <TR><TH HEIGHT=3></TH></TR> <TR><TD WIDTH=10></TD><TD> <P> Welcome to the UCSC Genome Browser website.
