	<h2>But</h2>
	<p>L'élément «&#160;<code>meter</code>&#160;» de HTML5 affiche une mesure scalaire dans une gamme connue. Étant donné que certains navigateurs ne prennent pas en charge cette fonctionnalité à l'origine, ce correctif émule la même fonctionnalité en utilisant HTML générique et WAI-ARIA.</p>

	<h2>How to implement</h2>
	<p>To use the polyfill, a standard <code>progress</code> element must be used. In cases where a browser doesn't support the <code>progress</code> element, the polyfill is automatically loaded.</p>
