问题描述
我正在尝试使用 use_percentages 生成具有按百分比显示背景位置的图像精灵.但是编译SCSS文件后，background-position声明还是以像素为单位.
I'm trying to use use_percentages to generate an image sprite with background position by percentage. But after compiling the SCSS file, the background-position declaration is still in pixels.
我的 SASS 代码:
My SASS code:
@import "compass/utilities/sprites";
$sprite-layout:smart;
$sprite-sprite-dimensions: true;
$use-percentages: true;
@import "images/sprite/*.png";
@include all-sprite-sprites;
如何让精灵图像按百分比定位?
How can I get the sprite images to be positioned by percentages?
推荐答案
在指定 use-percentages 参数时，您必须在变量中包含精灵图的名称，就像您已经完成的那样用于 layout.因此，只需将 $use-percentages: true; 更改为 $sprite-use-percentages: true;.
You have to include the name of your sprite map in the variable when specifying the use-percentages parameter, as you have already done for layout. So just change $use-percentages: true; to $sprite-use-percentages: true;.
