This is an intentional use of [protocol-relative URLs](http://paulirish.com/2010/the-protocol-relative-url/) **N.B.** Using a protocol-relative URL for files that exist on a CDN is problematic when you try to view your local files directly in the browser. The browser will attempt to fetch the file from your local file system. We recommend that you use a local server to test your pages (or Dropbox). This can be done using Python by running `python -m SimpleHTTPServer` from your local directory, using Ruby by installing and running [asdf](https://rubygems.org/gems/asdf), and by installing any one of XAMPP, MAMP, or WAMP. ### Why don't you automatically load the latest version of jQuery from the Google CDN? 1. The latest version of jQuery may not be compatible with the existing plugins/code on the site. Version updating should be an intentional decision. 2. The latest version has a very short `max-age=3600` compares to the specific version of `max-age=31536000`, which means you won't get the benefits of long-term caching. ### Why is the Google Analytics code at the bottom? Google recommends it be placed the `head`. The advantage to placing it in the `head` is that you will track a user's pageview even if they leave the page before it has been fully loaded. However, putting the code at the bottom keeps all the scripts together and reinforces that scripts at the bottom are the right move. ### How can I integrate [Twitter Bootstrap](http://twitter.github.com/bootstrap/) with HTML5 Boilerplate? You can use [Initializr](http://initializr.com) to create a custom build that includes HTML5 Boilerplate with Twitter Bootstrap. Read more about how [HTML5 Boilerplate and Twitter Bootstrap complement each other](http://www.quora.com/Is-Bootstrap-a-complement-OR-an-alternative-to-HTML5-Boilerplate-or-viceversa/answer/Nicolas-Gallagher). ### How do I prevent phone numbers looking twice as large and having a Skype highlight? If this is occurring, it is because a user has the Skype browser extension installed. Use the following CSS to prevent Skype from formatting the numbers on your page: ```css span.skype_pnh_container { display: none !important; } span.skype_pnh_print_container { display: inline !important; } ``` ### Do I need to upgrade my sites each time a new version of HTML5 Boilerplate is released? No. You don't normally replace the foundations of a house once it has been built. There is nothing stopping you from trying to work in the latest changes but you'll have to assess the costs/benefits of doing so. ### Where can I get help for support questions? Please ask for help on [StackOverflow](http://stackoverflow.com/questions/tagged/html5boilerplate).
