What this video covers
A screen reader is software that speaks (or sends to a braille display) what's on screen, letting blind and low-vision people use a computer by ear. Crucially, it turns a two-dimensional visual layout into a one-dimensional stream - read in source order, element by element - so the experience is linear, sequential, and entirely dependent on the meaning in your markup.
Step through the layout the way a screen reader does and the neat 2D grid became a single-file queue: image, heading, price, button, image, heading… one after another, no skimming. Suddenly it's obvious why source order, alt text and headings matter so much - by ear, they're the only things to navigate by. The picture you see is not the page they get.
