question about import google file

1. question descibe;

once, one css file(app.css) of my web project has sentence like this:

@import url(http://fonts.googleapi.com/css?family=Source+Sans+Pro:300,400,600,400italic);

then if you refresh your web page, you will wait a long time until the page dead.

so what's wrong???

2. Reason:

when you are in somearea that not allowed to connect to the whole internet, that means you cannot get the file ,

so the brower will connect all the time.

3. Solution:

change the code like this:

@import url(http://fonts.useso.com/css?family=Source+Sans+Pro:300,400,600,400italic);

republish the project to the web server.
