# Semantic markup
The accessible behavior of a native element is free and correct. Recreating it is expensive and
rarely complete.
## Use the element that means it
Buttons, links, form controls, lists and headings carry role, keyboard behavior and state to
assistive technology. A styled container with a click handler carries none of it.
## Distinguish links from buttons
A link navigates, a button performs an action. Choosing by appearance breaks expectations for
keyboard, screen reader and browser features such as opening in a new tab.
## Structure with headings and landmarks
Use one descriptive page title, a logical heading order without skipped levels, and landmark regions
for navigation, main content and complements. Many users navigate by these alone.
## Label every control
Associate a visible label with each input. Placeholders disappear on entry and are not labels;
icon-only controls need an accessible name.
## Describe meaningful images
Give informative images alt text conveying their purpose, and mark decorative images as such. Alt
text should say what the image communicates, not what it depicts.
