### Why is the URL for jQuery without `http`?
It is because of the use of [protocol-relative
URLs](http://paulirish.com/2010/the-protocol-relative-url/).
**N.B.** If you try to view the local web page directly in the browser, the
browser will fail to load the assets specified using protocol-relative URLs
as it will attempt to fetch them from the local file system. We recommend you
use a local HTTP server to test your web pages, or a file hosting service that
allows you to preview your web pages online (e.g.
[Dropbox](https://www.dropbox.com/)).
Setting up a local HTTP server can be done using there various
[one-liners](https://gist.github.com/willurd/5720255):
* PHP 5.4.0+ by running
[`php -S localhost:8080`](https://php.net/manual/en/features.commandline.webserver.php)
from your local directory
* Python 2.x by running `python -m SimpleHTTPServer` from your local directory
* Python 3.x by running `python -m http.server` from your local directory
* Ruby 1.9.2+ by running `ruby -run -ehttpd . -p8080` from your local directory
* Node.js by installing and running either
[`static -p 8080`](https://www.npmjs.org/package/node-static)
or [`http-server -p 8080`](https://www.npmjs.org/package/http-server)
A list of more complex HTTP servers can be found
[here](misc.md#servers-and-stacks).
### Why don't you automatically load the latest version of jQuery from the Google CDN?
The [file](https://ajax.googleapis.com/ajax/libs/jquery/1/jquery.js) to which
the Google [CDN](https://en.wikipedia.org/wiki/Content_delivery_network) points
to is [no longer updated and will stay locked at version `1.11.1` in order to
prevent inadvertent web
breakage](http://blog.jquery.com/2014/07/03/dont-use-jquery-latest-js/).
In general, version updating should be an intentional decision! You shouldn't
include a URL that will always point to the latest version, as that version:
* may not be compatible with the existing plugins/code on the site
* will have a very short cache time compare to the specific version,
which means that users won't get the benefits of long-term caching
### Why is the Google Analytics code at the bottom? Google recommends it be placed in the ``.
The main advantage of placing it in the `` is that you will track the
user's `pageview` even if they leave the page before it has been fully loaded.
However, having the code at the bottom of the page [helps improve
performance](http://stevesouders.com/efws/inline-scripts-bottom.php).
### How can I integrate [Bootstrap](http://getbootstrap.com/) with HTML5 Boilerplate?
One simple way is to use [Initializr](http://initializr.com) and create a
custom build that includes both HTML5 Boilerplate and
[Bootstrap](http://getbootstrap.com/).
Read more about how [HTML5 Boilerplate and Bootstrap complement each
other](https://www.quora.com/Is-Bootstrap-a-complement-or-an-alternative-to-HTML5-Boilerplate-or-viceversa/answer/Nicolas-Gallagher).
### Do I need to upgrade my site each time a new version of HTML5 Boilerplate is released?
No, same as you don't normally replace the foundation of a house once it
was built. However, 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 with support questions?
