提问by Nick
I'm trying to use as css content and image (base64), but when I load the page is loaded like a broken link image.
我正在尝试使用 css 内容和图像（base64），但是当我加载页面时，它就像一个断开的链接图像一样加载。
Now, i'm using a website to download the base64 image and this is the css that i'm using that gives me the broken images:
现在，我正在使用一个网站来下载 base64 图像，这是我正在使用的 css，它给了我损坏的图像：

}
if i open the "broken" base 64 image into a new chrome tab, this is the resulting error:
如果我将“损坏的”base 64 图像打开到新的 chrome 选项卡中，则会产生以下错误：
This page contains the following errors:
error on line 10 at column 1: Extra content at the end of the document Below is a rendering of the page up to the first error.
此页面包含以下错误：
第 1 列第 10 行的错误：文档末尾的额外内容 以下是直到第一个错误为止的页面呈现。
now, i've never used base64 images, but i have to do something special or it should be just copy and paste the autogenerated code?
现在，我从未使用过 base64 图像，但我必须做一些特别的事情，还是应该只是复制并粘贴自动生成的代码？
thanks in advance for the help
在此先感谢您的帮助

It is what it says, you've encoded the document + some additional garbage at the end.
这就是它所说的，您已经对文档进行了编码，最后还有一些额外的垃圾。
This would seem to be the correct encoding which I obtained by decoding via http://www.opinionatedgeek.com/dotnet/tools/Base64Encode/removing the garbage and then encoding using the same site.
这似乎是我通过http://www.opinionatedgeek.com/dotnet/tools/Base64Encode/解码获得的正确编码，删除垃圾，然后使用同一站点进行编码。

You can easily convert a SVG file to a base64 ecoded value for CSS background attribute with this simple bash command:
使用这个简单的 bash 命令，您可以轻松地将 SVG 文件转换为 CSS 背景属性的 base64 编码值：
echo "background: transparent url('data:image/svg+xml;base64,"$(openssl base64 < path/to/file.svg)"') no-repeat center center;"
Tested on Mac OS X. This way you also avoid the URL escaping mess.
在 Mac OS X 上测试过。这样你也可以避免 URL 转义混乱。
Remember that base64 encoding an SVG file increase its size, see css-tricks.com blog post
请记住，对 SVG 文件进行 base64 编码会增加其大小，请参阅css-tricks.com 博客文章
