Menu
I'm trying to load local css & js file when remote file is not available. (wifi dis-connected) The major problem is "I don't know how to let css load proper". As I know jquery should put on bottom of body to reduce page load time. In browser's address line, I input localhost:8000//example.html (use a static web page web browser).
Demo Code
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">

<meta name="viewport" content="width=device-width, initial-scale=1" />
<meta name="description" content="Go By Example - Google Go (golang) code examples" />
