---------正文开始--------
自从IE10发布,输入范围样式备受关注。 现在仅仅使用CSS就可以生成跨浏览器、可兼容的输入范围(滑块)。今天,我们就一起来简单实践下。
把上图变成这样:
为了简化生成样式的过程,为添加了LESS样式表,CSS也可用。
应用基础CSS样式被输入范围应用的几个样式需要添加到所有浏览器中,覆盖他们的基本外观。
input[type=range] { -webkit-appearance: none; /* Hides the slider so that custom slider can be made */ width: 100%; /* Specific width is required for Firefox. */ } input[type=range]::-webkit-slider-thumb { -webkit-appearance: none; } input[type=range]:focus { outline: none; /* Removes the blue border. You should probably do some kind of focus styling for accessibility reasons though. */ } input[type=range]::-ms-track { width: 100%; cursor: pointer; background: transparent; /* Hides the slider so custom styles can be added */ border-color: transparent; color: transpare
这个CSS在所有浏览器中,给我们不可见或者无样式的输入范围。现在我们可以使用定制样 式。
翻阅样式
接下来是我们对组件延路径点击、拖拽的样式设计,一个Html元素就可以实现。
/* Special styling for WebKit/Blink */ input[type=range]::-webkit-slider-thumb { -webkit-appearance: none; border: 1px solid #000000; height: 36px; width: 16px; border-radius: 3px; background: #ffffff; cursor: pointer; margin-top: -14px; /* You need to specify a margin in Chrome, but in Firefox and IE it is automatic */ box-shadow: 1px 1px 1px #000000, 0px 0px 1px #0d0d0d; /* Add cool effects to your sliders! */ } /* All the same stuff for Firefox */ input[type=range]::-moz-range-thumb { box-shadow: 1px 1px 1px #000000, 0px 0px 1px #0d0d0d; border: 1px solid #000000; height: 36px; width: 16px; border-radius: 3px; background: #ffffff; cursor: pointer; } /* All the same stuff for IE */ input[type=range]::-ms-thumb { box-shadow: 1px 1px 1px #000000, 0px 0px 1px #0d0d0d; border: 1px solid #000000; height: 36px; width: 16px; border-radius: 3px; background: #ffffff; cursor: pointer; }
我们在这里重复代码,如果你不能用多好分隔这些类型的选择符,那这步就必不可少。如果不向浏览器说清楚,他们坑能不会执行。 然后,我们得到下图
路径样式
翻阅的路径,可以使用普通的HTML元素。 IE浏览器注意:IE 10+范围输入会略有不同。在IE中,可以为上层(如图,路径的右边)和下层(如图,路径的左边)区域路径指定完全不同的风格。 另外要说明的,我们可以为路径应用焦点效果,他会在用户与其交互时发生改变。
input[type=range]::-webkit-slider-runnable-track { width: 100%; height: 8.4px; cursor: pointer; box-shadow: 1px 1px 1px #000000, 0px 0px 1px #0d0d0d; background: #3071a9; border-radius: 1.3px; border: 0.2px solid #010101; } input[type=range]:focus::-webkit-slider-runnable-track { background: #367ebd; } input[type=range]::-moz-range-track { width: 100%; height: 8.4px; cursor: pointer; box-shadow: 1px 1px 1px #000000, 0px 0px 1px #0d0d0d; background: #3071a9; border-radius: 1.3px; border: 0.2px solid #010101; } input[type=range]::-ms-track { width: 100%; height: 8.4px; cursor: pointer; background: transparent; border-color: transparent; border-width: 16px 0; color: transparent; } input[type=range]::-ms-fill-lower { background: #2a6495; border: 0.2px solid #010101; border-radius: 2.6px; box-shadow: 1px 1px 1px #000000, 0px 0px 1px #0d0d0d; } input[type=range]:focus::-ms-fill-lower { background: #3071a9; } input[type=range]::-ms-fill-upper { background: #3071a9; border: 0.2px solid #010101; border-radius: 2.6px; box-shadow: 1px 1px 1px #000000, 0px 0px 1px #0d0d0d; } input[type=range]:focus::-ms-fill-upper { background: #367ebd; }
然后得到下图:
构建一个完整的输入范围 之前,我们创建了滑块和路径,现在我们可以写CSS了。 兼容所有浏览器的完整的CSS样式范围输入
input[type=range] { -webkit-appearance: none; margin: 18px 0; width: 100%; } input[type=range]:focus { outline: none; } input[type=range]::-webkit-slider-runnable-track { width: 100%; height: 8.4px; cursor: pointer; animate: 0.2s; box-shadow: 1px 1px 1px #000000, 0px 0px 1px #0d0d0d; background: #3071a9; border-radius: 1.3px; border: 0.2px solid #010101; } input[type=range]::-webkit-slider-thumb { box-shadow: 1px 1px 1px #000000, 0px 0px 1px #0d0d0d; border: 1px solid #000000; height: 36px; width: 16px; border-radius: 3px; background: #ffffff; cursor: pointer; -webkit-appearance: none; margin-top: -14px; } input[type=range]:focus::-webkit-slider-runnable-track { background: #367ebd; } input[type=range]::-moz-range-track { width: 100%; height: 8.4px; cursor: pointer; animate: 0.2s; box-shadow: 1px 1px 1px #000000, 0px 0px 1px #0d0d0d; background: #3071a9; border-radius: 1.3px; border: 0.2px solid #010101; } input[type=range]::-moz-range-thumb { box-shadow: 1px 1px 1px #000000, 0px 0px 1px #0d0d0d; border: 1px solid #000000; height: 36px; width: 16px; border-radius: 3px; background: #ffffff; cursor: pointer; } input[type=range]::-ms-track { width: 100%; height: 8.4px; cursor: pointer; animate: 0.2s; background: transparent; border-color: transparent; border-width: 16px 0; color: transparent; } input[type=range]::-ms-fill-lower { background: #2a6495; border: 0.2px solid #010101; border-radius: 2.6px; box-shadow: 1px 1px 1px #000000, 0px 0px 1px #0d0d0d; } input[type=range]::-ms-fill-upper { background: #3071a9; border: 0.2px solid #010101; border-radius: 2.6px; box-shadow: 1px 1px 1px #000000, 0px 0px 1px #0d0d0d; } input[type=range]::-ms-thumb { box-shadow: 1px 1px 1px #000000, 0px 0px 1px #0d0d0d; border: 1px solid #000000; height: 36px; width: 16px; border-radius: 3px; background: #ffffff; cursor: pointer; } input[type=range]:focus::-ms-fill-lower { background: #3071a9; } input[type=range]:focus::-ms-fill-upper { background: #367ebd; }
输入范围完成:
附加风格设计
因为要兼容所有浏览器,CSS会比较大。使用预处理程序可以是其工作更加有效率。下面的LESS文件可以生成上面提到的CSS。
@track-color: #424242; @thumb-color: #555bc8; @thumb-radius: 8px; @thumb-height: 30px; @thumb-width: 30px; @thumb-shadow-size: 1px; @thumb-shadow-blur: 1px; @thumb-shadow-color: #111; @thumb-border-width: 1px; @thumb-border-color: white; @track-width: 100%; @track-height: 10px; @track-shadow-size: 2px; @track-shadow-blur: 2px; @track-shadow-color: #222; @track-border-width: 1px; @track-border-color: black; @track-radius: 5px; @contrast: 5%; .shadow(@shadow-size,@shadow-blur,@shadow-color) { box-shadow: @shadow-size @shadow-size @shadow-blur @shadow-color, 0px 0px @shadow-size lighten(@shadow-color,5%); } .track() { width: @track-width; height: @track-height; cursor: pointer; animate: 0.2s; } .thumb() { .shadow(@thumb-shadow-size,@thumb-shadow-blur,@thumb-shadow-color); border: @thumb-border-width solid @thumb-border-color; height: @thumb-height; width: @thumb-width; border-radius: @thumb-radius; background: @thumb-color; cursor: pointer; } input[type=range] { -webkit-appearance: none; margin: @thumb-height/2 0; width: @track-width; &:focus { outline: none; } &::-webkit-slider-runnable-track { .track(); .shadow(@track-shadow-size,@track-shadow-blur,@track-shadow-color); background: @track-color; border-radius: @track-radius; border: @track-border-width solid @track-border-color; } &::-webkit-slider-thumb { .thumb(); -webkit-appearance: none; margin-top: ((-@track-border-width * 2 + @track-height) / 2) - (@thumb-height / 2); } &:focus::-webkit-slider-runnable-track { background: lighten(@track-color, @contrast); } &::-moz-range-track { .track(); .shadow(@track-shadow-size,@track-shadow-blur,@track-shadow-color); background: @track-color; border-radius: @track-radius; border: @track-border-width solid @track-border-color; } &::-moz-range-thumb { .thumb(); } &::-ms-track { .track(); background: transparent; border-color: transparent; border-width: @thumb-width 0; color: transparent; } &::-ms-fill-lower { background: darken(@track-color, @contrast); border: @track-border-width solid @track-border-color; border-radius: @track-radius*2; .shadow(@track-shadow-size,@track-shadow-blur,@track-shadow-color); } &::-ms-fill-upper { background: @track-color; border: @track-border-width solid @track-border-color; border-radius: @track-radius*2; .shadow(@track-shadow-size,@track-shadow-blur,@track-shadow-color); } &::-ms-thumb { .thumb(); } &:focus::-ms-fill-lower { background: @track-color; } &:focus::-ms-fill-upper { background: lighten(@track-color, @contrast); } }
浏览器支持
自身支持范围输入的浏览器有: Firefox 23+, Safari 4+, iOS 5+, Chrome 6+, Opera 11+, IE 10+, Android 4.2+。如果你遵循本文中的代码,自定义样式应该很大程度上是匹配的。
