我想为所有浏览器制作mixin,包括IE9 IE9,IE8,IE7和Opera。

对于IE9,我们需要设置filter:none
使用IE9支持完整的多站梯度(使用SVG)。添加一个 “渐变”类对所有具有渐变的元素进行添加 以下覆盖HTML以完成IE9支持:
<!--[if gte IE 9]> <style type="text/css"> .gradient { filter: none; } </style> <![endif]-->
指南针有渐变http://compass-style.org/reference/compass/css3/images/的最新模块,我们可以在调用$experimental-support-for-svg: true
之后使用它,例如像这样使用
.gradient {@include linear-gradient(#000000, #ff0000)}
这给出了像这样的输出
.gradient {
background-image: url('data:image/svg+xml;base64,PD94bWwgdmVyc2lvbj0iMS4wIiBlbmNvZGluZz0idXRmLTgiPz4gPHN2ZyB2ZXJzaW9uPSIxLjEiIHhtbG5zPSJodHRwOi8vd3d3LnczLm9yZy8yMDAwL3N2ZyI+PGRlZnM+PGxpbmVhckdyYWRpZW50IGlkPSJncmFkIiBncmFkaWVudFVuaXRzPSJ1c2VyU3BhY2VPblVzZSIgeDE9IjUwJSIgeTE9IjAlIiB4Mj0iNTAlIiB5Mj0iMTAwJSI+PHN0b3Agb2Zmc2V0PSIwJSIgc3RvcC1jb2xvcj0iIzAwMDAwMCIvPjxzdG9wIG9mZnNldD0iMTAwJSIgc3RvcC1jb2xvcj0iI2ZmMDAwMCIvPjwvbGluZWFyR3JhZGllbnQ+PC9kZWZzPjxyZWN0IHg9IjAiIHk9IjAiIHdpZHRoPSIxMDAlIiBoZWlnaHQ9IjEwMCUiIGZpbGw9InVybCgjZ3JhZCkiIC8+PC9zdmc+IA==');
background-size: 100%;
background-image: -webkit-gradient(linear, 50% 0%, 50% 100%, color-stop(0%, #000000), color-stop(100%, #ff0000));
background-image: -webkit-linear-gradient(#000000, #ff0000);
background-image: -moz-linear-gradient(#000000, #ff0000);
background-image: -o-linear-gradient(#000000, #ff0000);
background-image: -ms-linear-gradient(#000000, #ff0000);
background-image: linear-gradient(#000000, #ff0000);
}
如果我们将 compass Image 代码与colorzilla代码进行比较
它缺少IE6-8
filter:progid:DXImageTransform.Microsoft.gradient(startColorstr ='#1e5799',endColorstr ='#7db9e8',GradientType = 0); / * IE6-8 * /
background: #1e5799; /* Old browsers */
background-image
代替background
background-size: 100%;
filter:none
。background-size: 100%;
的好处是什么?background-image
代替background
?filter:none
罗盘?filter:
progid:DXImageTransform.Microsoft.gradient( startColorstr='#1e5799',
endColorstr='#7db9e8',GradientType=0 );
?答案 0 :(得分:2)
背景大小有什么好处:100%;?
使用背景图片代替背景有什么好处?
SVG图像是背景图像,该属性的内容是以编程方式生成的图像。为了保持一致,Compass使用背景图像。此外,指定background-image
可以允许编码人员指定不会被混音影响的background-color
。
设置background-size
可确保图像实际伸展以填充元素的空间,而不是图像本身的大小。
有没有办法在Compass中为IE9添加filter:none?
如何在指南针中获得IE6-8兼容代码,例如此过滤器:progid:DXImageTransform.Microsoft.gradient(startColorstr ='#1e5799',endColorstr ='#7db9e8',GradientType = 0);?
这两个选项有三种选择:
答案 1 :(得分:1)
首先在_base.scss
中尝试一下@import "compass/support";
$legacy-support-for-ie7: true;
$legacy-support-for-ie8: true;
$experimental-support-for-microsoft: true;
$experimental-support-for-pie: false;
$experimental-support-for-svg: true;
然后加入
@import filter-gradient($ start-color,$ end-color,$ orientation)
