问题描述
我想为两种不同的场景使用Compass生成的icon-sprite。
- 使用原始大小的图标。
- 使用与使用CSS3属性
background-size
的较小版本相同的图标。
我首先这样做:
$ logo-spacing: 20px;
@importlogo / *。png;
@include all-logo-sprites;
现在我可以使用一般创建的CSS类,如 .logo-twitter
两个实现第二个结果我可以使用这个():
@mixin resize-sprite ,$ sprite,$ percent){
$ spritePath:sprite-path($ map);
$ spriteWidth:image-width($ spritePath);
$ spriteHeight:image-height($ spritePath);
$ width:image-width(sprite-file($ map,$ sprite));
$ height:image-height(sprite-file($ map,$ sprite));
@include background-size(ceil($ spriteWidth *($ percent / 100))ceil($ spriteHeight *($ percent / 100)
width:ceil($ width *($ percent / 100));
height:ceil($ height *($ percent / 100));
background-position:0 floor(nth(sprite-position($ map,$ sprite),2)*($ percent / 100)
}
.my-other-div-with-small-logos {
.logo-twitter {
$ spriteName:twitter;
$ percentage:40;
@include resize-sprite($ logo-sprites,$ spriteName,$ percentage);
}
}
但如果我有大约30个标志,
可以导入文件夹两次,一次为原始大小,第二次导入 backround-size
属性?
或修改所提到的方法以在另一个< div class =my-other-div-with-small-logos>
中自动创建所有类
/ div>
就是这样。它遍历整个映射:
@each $ sprite in sprite_names($ logo-sprites){
.logo - #{$ sprite} {
@include resize-sprite($ logo-sprites,$ sprite,40);
}
}
这有助于:
这是伟大的缩放在现代浏览器中没有加载另一个生成的精灵图像。如果标志有时是50像素,但在其他地方也应该是20像素,这是非常好的。
I want to use a Compass generated icon-sprite for two different scenarios.
- Use the icon(s) in original size.
- Use it the same icon(s) as a smaller version using CSS3 property
background-size
.
I first do this:
$logo-spacing: 20px;
@import "logo/*.png";
@include all-logo-sprites;
Now I can use the general created CSS-classes like .logo-twitter
etc.
Two achieve the second result I could use this (darren131 / gist:3410875 - resize sprites in Compass):
@mixin resize-sprite($map, $sprite, $percent) {
$spritePath: sprite-path($map);
$spriteWidth: image-width($spritePath);
$spriteHeight: image-height($spritePath);
$width: image-width(sprite-file($map, $sprite));
$height: image-height(sprite-file($map, $sprite));
@include background-size(ceil($spriteWidth * ($percent/100)) ceil($spriteHeight * ($percent/100)));
width: ceil($width*($percent/100));
height: ceil($height*($percent/100));
background-position: 0 floor(nth(sprite-position($map, $sprite), 2) * ($percent/100) );
}
.my-other-div-with-small-logos {
.logo-twitter {
$spriteName: twitter;
$percentage: 40;
@include resize-sprite($logo-sprites, $spriteName, $percentage);
}
}
But if I have around 30 logos I would need to repeat this manually for each sprite-class.
Is it possible to import the folder twice, once for the original size and a second time with the backround-size
property?Or modify the mentioned method to create all classes automatically within another <div class="my-other-div-with-small-logos">
where the icons should appear smaller?
Or am I thinking in the wrong direction here?
That does it. It iterates over the whole map:
@each $sprite in sprite_names($logo-sprites) {
.logo-#{$sprite} {
@include resize-sprite($logo-sprites, $sprite, 40);
}
}
This helped: Way to iterate over sprites in a map
It's great to scale down sprites in modern Browsers without loading another generated sprite-image. If the logos sometimes are 50px, but should also be 20px somewhere else, this is perfectly fine.
