使用 sass --style 压缩后的某些样式未在浏览器中呈现 [英] Some styles not rendered in the browser with sass --style compressed

问题描述

我通过将单个 .css 文件重命名为 .scss 并将它们@import 合并到一个主文件中，重构了一些普通 CSS.该文件的内容如下所示:

I refactored some vanilla CSS by renaming individual .css files as .scss and @importing them into one master file. The contents of that file looks like this:

@import file1
@import file2
@import file3

在同一个目录下，_file1.scss、_file2.scss、_file3.scss.

In the same directory, lives _file1.scss, _file2.scss, _file3.scss.

一切正常，但由于某种原因，当我添加标志 --style 压缩 时，缩小的输出缺少类等.它也适用于 --style compact所以无论出现什么问题都是特定于压缩的.

Everything works, but for some reason, when I add the flag --style compressed the minified output is missing classes, etc. It also works fine with --style compact so whatever is going wrong is specific to compressed.

我使用的是 OSX 10.9.2，使用 Sass v3.2.10 (Media Mark).我正在使用以下命令:

I'm on OSX 10.9.2, with Sass v3.2.10 (Media Mark). I'm using the following command:

sass --watch style.style.min.css --style compressed

当我不缩小输出(通过删除 --style 压缩)时，生成的 CSS 工作正常.

When I do NOT minify the output (by removing --style compressed) the resulting CSS works fine.

有什么想法可能出问题了吗?

Any ideas what could be going wrong?

具体代码:我无法发布整个文件，但这里有一个示例，其中包含无法正常工作的代码...

Specific code: I can't post the whole file but here's a sample with the code that's not working...

.scss

/*!XXXXXXXXXX*/
/* route colors */
.subway_metrorail_red       { background:#e45340; color:#fff; }
.subway_metrorail_orange    { background:#efaa49; color:#fff; }
.subway_metrorail_yellow    { background:#7a7a17; color:#fff; }
.subway_metrorail_green     { background:#52b05f; color:#fff; }
.subway_metrorail_blue      { background:#3f8cda; color:#fff; }

(缩小).css

... .subway_metrorail_blue h3{color:#000}/*!XXXXXXXXXX*/.subway_metrorail_red{background:#e45340;color:#fff}.subway_metrorail_orange{background:#efaa49;color:#fff} ...

更新:我开始认为这与 sass 编译 CSS 无关...如果我采用与 --compact 完全相同的代码并添加一两个换行符，样式会得到正常应用.CSS文件或其他东西有最大行长吗?

UPDATE: I'm starting to think this has nothing to do with sass compiling the CSS... If I take the exact same code that results from --compact and add one line break or two, the styles get applied normally. Is there a maximum line length for CSS files or something?

更新 2:

验证器不喜欢这样:

.car2go_icon {
    background-image:url("../images/car2go_logo_50.png");
    background-size: 158px 50px;
    background-position: 0px 20px;
    background-repeat:no-repeat;
    -ms-filter: "progid:DXImageTransform.Microsoft.AlphaImageLoader(
    src='../../../public/images/car2go_logo_50.png',
    sizingMethod='crop')";
}

更新 3:我认为 -ms-filter: 之后字符串中的换行符是问题所在！当我离开上面的代码时，它们验证失败.但是当我删除换行符时，它们似乎通过了.我有一种感觉，这在放大过程中会破裂.有没有人比我更了解 -ms-filter 的正确语法?

UPDATE 3: I think the line breaks within the string after -ms-filter: are the problem! They fail validation when I leave the code as you see it above. But when I remove the line breaks they seem to pass. I have a feeling that this is breaking during magnification. Does anyone know more about the correct syntax for -ms-filter than me?

推荐答案

这可能不起作用，因为 css 行数超过 4000+.如果您尝试将一些 sass 放在另一个文件中并使每个文件少于 4000 行，我认为这对您有用.

This may not working because number of css lines exceeding 4000+. If you try to put some of your sass in another files and make each file under 4000 lines I think that will work for you.
