Question

以下使用sass / compass生成base64内嵌图像：

background-image:inline-image("paper.jpg", 'image/jpg');

有没有办法做多个背景图片，还是我必须自己预压缩才能做到？

感谢。

Answer 1

内联图像函数只输出url（）字符串，因此你可以通过这样做来使用多个：

background: inline-image("front-image.jpg", 'image/jpg') no-repeat, inline-image("back-image.jpg", 'image/jpg') repeat-x

你会得到以下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”，否则前面图像会重复并覆盖背面图像。

我正在使用sencha touch 2并找到了下一个sass扩展名：

<强> 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

<强> 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

见用法：

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");
