ALT Léonie Watson is Director of TetraLogical; a member of the W3C Advisory Board; co-Chair of the W3C Web Applications Working Group; and until recently was a member of the Accelerated Mobile Pages (AMP) Advisory Committee. Léonie is often found at conferences, talking about web standards, accessibility mechanics, and pushing the boundaries of inclusive design. Her session is titled “Accessibility: the land that time to interactive forgot”: We tend to think of performance in terms of latency, code optimization, and things like the critical rendering path, but what happens when the browser creates an accessibility tree as well as the DOM? The answer is of course “it depends…”. Different browsers take different approaches, but they all have an impact on performance and the Time To Interactive in particular.
