javascript - Writing CSS right before the closing body tag

Question

I'm trying to write one line of CSS using vanilla JavaScript inside the document.body, but right before the closing </body> tag.

What am I doing wrong, why isn't this working?

document.body.write('<style type="text/css">#input, #backgroundFix{ background:url(dawn.svg) top left repeat-x; }</style>');

假设您的脚本也位于结束标记之前，则它是document.write，不是。document.body.write</body>

如果没有，请document.createElement改用。
