Meter polyfill
Looking for WET v3.1?
WET v4.0 is now the current version. There is a new location for the current page in WET v3.1.
Purpose
The HTML5 meter element displays a scalar measurement within a known range. Because some browsers do not support this functionality natively, this polyfill emulates the same functionality using generic HTML and WAI-ARIA.
Use when
- Displaying a scalar measurement within a known range
Do not use when
- Displaying the progress of a task
Working example
Normal
<meter min="20" value="65" max="80">75% (normal)</meter>Too high
<meter min="0" value="90" max="100" high="80">90% (too high)</meter>Too low
<meter min="100" low="120" value="115" max="200" high="180">15% (too low)</meter>How to implement
To use the polyfill, a standard progress element must be used. In cases where a browser doesn't support the progress element, the polyfill is automatically loaded.
Configuration options
Configuration options available for the meter element (HTML5 specification)
