Gzip压缩的css文件与php header，第一行ZC7A628CBA22E28EB167B5F5C6AE2A不起作用

Question

I am using gzip to compress my files so I need to add the following code to the top.

ob_start("ob_gzhandler");
header("content-type: text/css; charset: UTF-8");
header("cache-control: must-revalidate");
header("expires: ".gmdate('D, d M Y H:i:s', time() + 1000)." GMT"); 

The problem is now that the first line of css code in my file does not work. eg

body{
  color: red;
  font-weight: bold;
}

using this the text would be bold but not red.

Looking forward to an advice.

Thanks in advance.

Answer 1

Edit:

From the comments, it turned out to be because:

the php code was inserting something into the css file.

Probably either:

• an unprintable character similar to this: CSS: Is there any difference between these two parts?
• or a UTF-8 BOM .

The font-color property does not exist.

Use color: red instead.

If the text is indeed bold, then your CSS file is working, so there shouldn't be any more problems.

Although I think the last line of your PHP should be:

header("expires: ".gmdate('D, d M Y H:i:s', time() + 1000)." GMT");
