一个简单的问题.我应该在CSS中使用什么引号?

Simple question. What quotation marks should I use in CSS?

选项1:

background: url( 'foo.png' );

选项2:

background: url( "foo.png" );

两者都可以在普通浏览器"上使用.我只想遵循这些标准.

Both works on "normal browsers". I just want to follow the standards.

推荐答案

标准说 :

URI值的格式为'url('，后跟可选的空格，后跟可选的单引号(')或双引号()字符，后跟URI本身，然后是可选的单引号(')或双引号()字符，后跟可选空格，后跟')'.两个引号字符必须相同.

The format of a URI value is 'url(' followed by optional white space followed by an optional single quote (') or double quote (") character followed by the URI itself, followed by an optional single quote (') or double quote (") character followed by optional white space followed by ')'. The two quote characters must be the same.

即无，单或双.如果您在意IE5/Mac(如今可能不太喜欢)，请避免使用'，否则请使用使您感到舒适的任何东西.

i.e. none, single or double. If you care about IE5/Mac (which you probably don't these days) avoid ', otherwise use whatever makes you comfortable.
