When the order of content affects its meaning, that order must be preserved in the underlying code.

What it means
The visual order in which content appears on screen is often meaningful. A step-by-step process, a question followed by an answer, or a sequence of instructions must be read in the correct order to make sense.
When assistive technologies read content, they follow the order in the underlying code, not the visual layout. If CSS positioning places content visually in one order but the HTML is structured differently, screen reader users experience the content in the wrong order.
In practice
Write HTML in the order you want it to be read, then use CSS for visual positioning. Never use CSS to reorder content that must be read in a specific sequence.
Test your page by viewing it without CSS. The content should still make sense in the order it appears.
Be careful with CSS flexbox and grid order properties, which can move elements visually without changing the DOM order.
Common failures
- Multi-step instructions where the HTML order does not match the intended reading sequence
- Using CSS
position: absoluteto visually reorder content so it reads differently in the DOM - Multi-column layouts where the reading order jumps between columns in a confusing way when CSS is removed
