下面这段代码使用sass/compass生成一个base64内联图像:
background-image:inline-image("paper.jpg", 'image/jpg');
有没有一种方法可以使用多个背景图像,或者我必须自己预压缩它们才能这样做?
谢谢。

background: inline-image("front-image.jpg", 'image/jpg') no-repeat, inline-image("back-image.jpg", 'image/jpg') repeat-x
您将获得以下CSS:
background: url('data:"image/jpg";base64,FRONTIMAGEDATAHERE') no-repeat, url('data:"image/jpg";base64,BACKIMAGEDATAHERE') repeat-x;
我添加了"no-repeat"和"repeat-x"属性,否则前景图片会重复并覆盖背景图片。
我正在使用Sencha Touch 2,并找到了适用于它的下一个Sass扩展:
theme_images.rb:
module SenchaTouch
module SassExtensions
module Functions
module ThemeImages
def theme_image(theme, path, mime_type = nil)
path = path.value
images_path = File.join(File.dirname(__FILE__), "..", "images", theme.value)
real_path = File.join(images_path, path)
inline_image_string(data(real_path), compute_mime_type(path, mime_type))
end
end
end
end
end
module Sass::Script::Functions
include SenchaTouch::SassExtensions::Functions::ThemeImages
end
compass_init.rb:
# This file registers the sencha-touch framework with compass
# It's a magic name that compass knows how to find.
dir = File.dirname(__FILE__)
require File.join(dir, 'lib', 'theme_images.rb')
Compass::Frameworks.register 'sencha-touch', dir
查看用法:
background: theme_image($theme-name, "clear_icon.png") no-repeat;
-webkit-mask: theme_image($theme-name, "select_mask.png");
-webkit-mask-image: theme_image($theme-name, "pictos/arrow_down.png");
