<h1>对比度</h1>
<p>Contrast is all about the juxtaposition of opposing elements. If you think of it like the setting on a TV or the slider on a photo manipulation app, it alters the colors such that they are more distinct from one another. But the concept of contrast can be far more than that.</p>
<p>适用浏览器：Chrome、FireFox、360、搜狗、Opera、傲游. 不支持Windows版Safari、IE8及以下浏览器。</p>
