何谓HSLHSL色彩模式:就是色调(Hue)、饱和度(Saturation)、亮度(Lightness)三个颜色通道的改变以及它们相互之间的叠加来获得各种颜色,色调(Hue)色调最大值360,饱和度和亮度有百分比表示0-100%之间。
因为人们看到颜色第一时间会产生“这是什么颜色?深浅如何?明暗如何?”这个疑问不是这是多少红加多少绿多少蓝混合而成的颜色,所以HSL色彩模式是人类对颜色最直接的感知。
HSL(H S L)
H:
Hue(色调)。0(或360)表示红色,120表示绿色,240表示蓝色,也可取其他数值来指定颜色。取值为:0 - 360
S:
Saturation(饱和度)。取值为:0.0% - 100.0%
L:
Lightness(亮度)。取值为:0.0% - 100.0%
HSL被现代浏览器较好的支持,而且不需要任何前缀,IE6-IE7不支持。IE8支持该方式。
实例1:在css中直接使用hsl值
<style>.test{background-color:hsl(360 50% 50%);}</style>
实例2:使用Js修改dom时指定hsl值,以亮度为例
html:
<style> body { padding: 100px; } #ex1Slider .slider-selection { background: #BABABA; } </style> <div class="form"> <div class="form-group"> <label for="">亮度:</label> <input id="ex1" data-slider-id="ex1Slider" type="text" data-slider-min="0" data-slider-max="100" data-slider-step="1" data-slider-value="15" /> </div> </div>
//亮度$('#ex1').slider().on('change' function (e) { var newValue = e.value.newValue; console.info(newValue); $(document.body).css({ backgroundColor: 'hsl(360 50% ' newValue '%)' });});
完整代码:

效果如下:
实例3:修改多个值:
html:
<style> body { padding:100px; } .form-group { margin-bottom:50px; } #ex1Slider .slider-selection { background: #BABABA; } </style> <div class="form"> <div class="form-group"> <label for="">色 调:</label> <input id="Hue" data-slider-id="ex1Slider" type="text" data-slider-min="0" data-slider-max="360" data-slider-step="1" data-slider-value="180" /> </div> <div class="form-group"> <label for="">饱和度:</label> <input id="Saturation" data-slider-id="ex1Slider" type="text" data-slider-min="0" data-slider-max="100" data-slider-step="1" data-slider-value="50" /> </div> <div class="form-group"> <label for="">亮 度:</label> <input id="Lightness" data-slider-id="ex1Slider" type="text" data-slider-min="0" data-slider-max="100" data-slider-step="1" data-slider-value="50" /> </div> </div>
js:
//色调$('#Hue').slider().on('change' function (e) { showColor();});//饱和度$('#Saturation').slider().on('change' function (e) { showColor();});//亮度$('#Lightness').slider().on('change' function (e) { showColor();});//统一显示颜色function showColor() { var h = $('#Hue').slider('getValue'); var s = $('#Saturation').slider('getValue'); var l = $('#Lightness').slider('getValue'); var value = 'hsl(' h ' ' s '% ' l '%)'; console.info(value); $(document.body).css({ backgroundColor:value });}showColor();
