Jun 01, 2016 pm 02:32 PM

  在实现特定显示效果的页面中,css的filter属性是一种强大的工具。它能让我们的页面更加地个性化并减少PS方面的工作。filter的属性值主要有以下十种:

    1. blur
    2. grayscale
    3. sepia
    4. saturate
    5. hue-rotate
    6. invert
    7. brightness
    8. contrast
    9. opacity
    10. drop-shadow

  本文使用的图片如下:

  一、blur属性。blur的使用格式一般为 filter: blur(1px); -webkit-filter: blur(1px); 该属性用来为元素增加模糊效果,显示效果如下:

  二、grayscale属性。grayscale的使用格式一般为 filter: grayscale(0.6); -webkit-filter: grayscale(0.6); 该属性用来设置元素的灰度,可以使彩色图片变为黑白,显示效果如下:

  三、sepia属性。sepia的使用格式一般为 filter: sepia(0.6); -webkit-filter: sepia(0.6); 该属性用来设置元素的褐色,显示效果如下:

  四、saturate属性。saturate的使用格式一般为: filter: saturate(0.15); -webkit-filter: saturate(0.15); 该属性常用来改变图片的饱和度,显示效果如下:

  五、hue-rotate属性。hue-rotate的使用格式一般为: filter: hue-rotate(189deg); -webkit-filter: hue-rotate(189deg); 该属性常用来改变图片的色相,显示效果如下:

  六、invert属性。invert的使用格式一般为: filter: invert(56%); -webkit-filter: invert(56%); 该属性用来实现反色,invert做出来的效果就像是我们照相机底面的效果一样,显示效果如下:

  七、brightness属性。brightness的使用格式一般为: filter: brightness(300%); -webkit-filter: brightness(300%); 该属性用来设置图片的亮度,显示效果如下:

  八、contrast属性。contrast的使用格式一般为: filter: contrast(56%); -webkit-filter: contrast(56%); 该属性用来改变图片的对比度,显示效果如下:

  十、drop-shadow属性。drop-shadow的使用格式一般为: filter: drop-shadow(10px 10px 10px yellow); -webkit-filter: drop-shadow(10px 10px 10px yellow); 用来给图片增加阴影效果,与box-shadow类似,显示效果如下:

<span style="color: #800000;">-ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=50)";
