我正在使用Ultimate CSS Gradient Generator创建径向渐变,它提供了Sass包含但无法完成background-image mixin
CSS
background: rgb(220,156,118);
background: -moz-radial-gradient(center, ellipse cover, rgba(220,156,118,1) 0%, rgba(220,156,118,1) 49%, rgba(214,101,90,1) 92%, rgba(214,101,90,1) 100%);
background: -webkit-gradient(radial, center center, 0px, center center, 100%, color-stop(0%,rgba(220,156,118,1)), color-stop(49%,rgba(220,156,118,1)), color-stop(92%,rgba(214,101,90,1)), color-stop(100%,rgba(214,101,90,1)));
background: -webkit-radial-gradient(center, ellipse cover, rgba(220,156,118,1) 0%,rgba(220,156,118,1) 49%,rgba(214,101,90,1) 92%,rgba(214,101,90,1) 100%);
background: -o-radial-gradient(center, ellipse cover, rgba(220,156,118,1) 0%,rgba(220,156,118,1) 49%,rgba(214,101,90,1) 92%,rgba(214,101,90,1) 100%);
background: -ms-radial-gradient(center, ellipse cover, rgba(220,156,118,1) 0%,rgba(220,156,118,1) 49%,rgba(214,101,90,1) 92%,rgba(214,101,90,1) 100%);
background: radial-gradient(ellipse at center, rgba(220,156,118,1) 0%,rgba(220,156,118,1) 49%,rgba(214,101,90,1) 92%,rgba(214,101,90,1) 100%);
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#dc9c76', endColorstr='#d6655a',GradientType=1 );
这是Sass mixin @includes
background-color: rgb(220,156,118);
@include filter-gradient(#dc9c76, #d6655a, horizontal);
@include background-image(radial-gradient(center, ellipse cover, rgba(220,156,118,1) 0%,rgba(220,156,118,1) 49%,rgba(214,101,90,1) 92%,rgba(214,101,90,1) 100%));
我能够为滤镜渐变
创建mixin@mixin filter-gradient($color1, $color2, $direction){
filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='$color1', endColorstr='$color2',GradientType=$direction);}
然而,由于颜色停止
,有点坚持为径向渐变创建mixin@mixin background-image($gradient($position, $type, $rgba1, $rgba2, $rgba3, $rgba4){
background: rgb(220,156,118);
background: -moz-$gradient(center, $type, $rgba1, $rgba2, $rgba3, $rgba4);
background: -webkit-gradient(radial, center center, 0px, center center, 100%, color-stop(0%,rgba(220,156,118,1)), color-stop(49%,rgba(220,156,118,1)), color-stop(92%,rgba(214,101,90,1)), color-stop(100%,rgba(214,101,90,1)));
background: -webkit-$gradient(center, $type, $rgba1, $rgba2, $rgba3, $rgba4);
background: -o-$gradient(center, $type, $rgba1, $rgba2, $rgba3, $rgba4);
background: -ms-$gradient(center, $type, $rgba1, $rgba2, $rgba3, $rgba4);
background: $gradient(ellipse at center, $rgba1, $rgba2, $rgba3, $rgba4);
};
你会怎么写这些?
答案 0 :(得分:2)
你应该尝试使用Compass,它是一组很有用的mixin(如渐变),适用于跨浏览器行为的最佳实践。
radial-gradient($color-stops, $center-position, $image)
由于webkit的限制,如果使用基于像素的色块,径向渐变mixin效果最佳。
Examples:
// Defaults to a centered, 100px radius gradient
+radial-gradient(color-stops(#c00, #00c))
// 100px radius gradient in the top left corner
+radial-gradient(color-stops(#c00, #00c), top left)
// Three colors, ending at 50px and passing thru #fff at 25px
+radial-gradient(color-stops(#c00, #fff, #00c 50px))
// A background image on top of a 100px radius gradient; requires an image
// with an alpha-layer.
+radial-gradient(color_stops(#c00, #fff), top left, image-url("noise.png")))
