This is first page of this presentation, at start we have three slides. all content is already loaded.
There're three navigation features: 1) links below 2) arrows at the bottom of strip on the left 3) arrow key on the keyboard.
All content of this page is already loaded, pictures, and text. Javascript controls how this content is displayed and what is hidden.
Every slide has its own, specific illustration on the right and this big number in the background in the right top corner.
For slides, now there's only two options for navigation - those arrows in the left bottom corner, and the key arrow on the keyboard.
This term means ability of any important content to be rendered to any user, irrelevant from any limitations - user and his device alike.
Because content is here, JS only hides it, without JS this is normal, linear, easy to access page.
Not only slides in a row, and a start. Every slide can have its own sublevel of navigation. Almost all is just the copypaste. More info at 1.0 slide
Without RWD almost always Web Accessibility is not applied. That's why only after getting RWD one can test Web Accessibility.
