aria-hidden: true is the approach I'd recommend for hiding inline SVG markup, since it hides the entire document fragment. Or it should, anyway, if the AT are implementing aria-hidden correctly; I've had testers say that they needed to add role="presentation" all the way down the tree to properly hide a fragment from some browser/AT combos. Depending on the context, you could also hide the details of the markup by a role with the children presentational property to a parent element, provided its name isn't derived from contents. So, if you have an SVG icon inside a button, and that button has an aria-label, then you shouldn't need to explicitly hide the SVG markup. More generally: if the SVG does not include any text content, alt text content, or interactive content, then according to our latest mapping recommendations, role="presentation" on the <svg> should effectively remove the SVG from the accessibility tree: basic shapes and use elements are only supposed to be included if the author has given them alt text, a role, or interactivity. But my recommendation would be to only use role="presentation" for cases when you want the SVG to be transparent (e.g., styled text where you just want the text content read out without identifying it as a graphic), and use aria-hidden for actually hiding redundant or purely decorative content. One other thing: to prevent the <svg> element from gaining tab focus in IE/Edge, add a (obsolete, defined in SVG Tiny 1.2) focusable="false" attribute. ~Amelia On 5 July 2016 at 16:45, James Nurthen <james.nurthen@oracle.com> wrote: > I found myself needing to hide some decorative SVG graphics from the > accessibility API today.
