如何使用

无需任何操作。在加载此插件后，将显示一个预览器，并在代码块中将鼠标悬停在一些值上。支持以下预览器

此插件兼容 CSS、Less、标记属性、Sass、Scss 和 Stylus。

示例

CSS

.example-gradient {
	background: -webkit-linear-gradient(left,     #cb60b3 0%, #c146a1 50%, #a80077 51%, #db36a4 100%); /* Chrome10+, Safari5.1+ */

}
@angle: 3rad;
.example-angle {
	transform: rotate(.4turn)
}
@nice-blue: #5B83AD;
.example-color {
	color: hsla(102, 53%, 42%, 0.4);
}
@easing: cubic-bezier(0.1, 0.3, 1, .4);
.example-easing {
	transition-timing-function: ease;
}
@time: 1s;
.example-time {
	transition-duration: 2s;
}

Sass

$gradient: linear-gradient(135deg, #9dd53a 0%, #a1d54f 50%, #80c217 51%, #7cbc0a 100%)
@mixin example-gradient
	background: -moz-radial-gradient(center, ellipse cover, #f2f6f8 0%, #d8e1e7 50%, #b5c6d0 51%, #e0eff9 100%)
	background: radial-gradient(ellipse at center, #f2f6f8 0%, #d8e1e7 50%, #b5c6d0 51%, #e0eff9 100%)
$angle: 380grad
@mixin example-angle
	transform: rotate(-120deg)
.example-angle
	transform: rotate(18rad)
$color: blue
@mixin example-color
	color: rgba(147, 32, 34, 0.8)
.example-color
	color: pink
$easing: ease-out
.example-easing
	transition-timing-function: ease-in-out
$time: 3s
@mixin example-time
	transition-duration: 800ms
.example-time
	transition-duration: 0.8s

Scss

$gradient: linear-gradient(135deg, #9dd53a 0%, #a1d54f 50%, #80c217 51%, #7cbc0a 100%);
$attr: background;
.example-gradient {
	#{$attr}-image: repeating-linear-gradient(10deg, rgba(255, 0, 0, 0), rgba(255, 0, 0, 1) 10px, rgba(255, 0, 0, 0) 20px);
}
$angle: 1.8turn;
.example-angle {
	transform: rotate(-3rad)
}
$color: blue;
.example-color {
	#{$attr}-color: rgba(255, 255, 0, 0.75);
}
$easing: linear;
.example-easing {
	transition-timing-function: cubic-bezier(0.9, 0.1, .2, .4);
}
$time: 1s;
.example-time {
	transition-duration: 10s
}

Stylus

gradient = linear-gradient(135deg, #9dd53a 0%, #a1d54f 50%, #80c217 51%, #7cbc0a 100%)
.example-gradient
	background-image: repeating-radial-gradient(circle, rgba(255, 0, 0, 0), rgba(255, 0, 0, 1) 10px, rgba(255, 0, 0, 0) 20px)
angle = 357deg
.example-angle
	transform: rotate(100grad)
color = olive
.example-color
	color: #000
easing = ease-in
.example-easing
	transition-timing-function: ease-out
time = 3s
.example-time
	transition-duration: 0.5s

禁用预览器

默认情况下，所有预览器都已启用。若要仅启用它们的子集，则可以在代码块或任何祖先代码块上添加 data-previewers 属性。其值应该是表示子集的以空格分隔的预览器列表。

例如

<pre class="language-css" data-previewers="color time"><code>div {
	/* Only the previewer for color and time are enabled */
	color: red;
	transition-duration: 1s;
	/* The previewer for angles is not enabled. */
	transform: rotate(10deg);
}</code></pre>

将产生以下结果

div {
	/* Only the previewers for color and time are enabled */
	color: red;
	transition-duration: 1s;
	/* The previewer for angles is not enabled. */
	transform: rotate(10deg);
}

API

此插件提供了一个可通过 Prism.plugins.Previewer 访问的构造函数。

实例化预览器后，将向文档正文中添加一个 HTML 元素。当将鼠标悬停在特定标记上时，此元素将显示。

new Prism.plugins.Previewer(type, updater, supportedLanguages)
