You can find out more in [the +Apple developer docs](https://developer.apple.com/library/safari/documentation/AppleApplications/Reference/SafariWebContent/UsingtheViewport/UsingtheViewport.html). +HTML5 Boilerplate comes with a simple setup that strikes a good balance for general use cases. + +```html +<meta name="viewport" content="width=device-width, initial-scale=1"> +``` + +## Favicons and Touch Icon + +The shortcut icons should be put in the root directory of your site. HTML5 +Boilerplate comes with a default set of icons (include favicon and one Apple +Touch Icon) that you can use as a baseline to create your own. + +Please refer to the more detailed description in the [Extend section](extend.md) +of these docs. + +## Modernizr + +HTML5 Boilerplate uses a custom build of Modernizr. + +[Modernizr](http://modernizr.com) is a JavaScript library which adds classes to +the `html` element based on the results of feature test and which ensures that +all browsers can make use of HTML5 elements (as it includes the HTML5 Shiv). +This allows you to target parts of your CSS and JavaScript based on the +features supported by a browser. + +In general, in order to keep page load times to a minimum, it's best to call +any JavaScript at the end of the page because if a script is slow to load +from an external server it may cause the whole page to hang. That said, the +Modernizr script *needs* to run *before* the browser begins rendering the page, +so that browsers lacking support for some of the new HTML5 elements are able to +handle them properly. Therefore the Modernizr script is the only JavaScript +file synchronously loaded at the top of the document. + +## What about polyfills? + +If you need to include [polyfills](https://remysharp.com/2010/10/08/what-is-a-polyfill) +in your project, you must make sure those load before any other JavaScript. If you're +using some polyfill CDN service, like [cdn.polyfill.io](https://cdn.polyfill.io/), +just put it before the other scripts in the bottom of the page: + +```html + <script src="https://cdn.polyfill.io/v1/polyfill.min.js"></script> + <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script> + <script>window.jQuery || document.write('<script src="js/vendor/jquery-1.11.2.min.js"><\/script>')</script> + <script src="js/plugins.js"></script> + <script src="js/main.js"></script> +</body> +``` + +If you like to just include the polyfills yourself, you could include them in +`js/plugins.js`. When you have a bunch of polyfills to load in, you could +also create a `polyfills.js` file in the `js/vendor` directory. Also using +this technique, make sure the polyfills are all loaded before any other +Javascript. + +There are some misconceptions about Modernizr and polyfills. It's important +to understand that Modernizr just handles feature checking, not polyfilling +itself. The only thing Modernizr does regarding polyfills is that the team +maintains [a huge list of cross Browser polyfills](https://github.com/Modernizr/Modernizr/wiki/HTML5-Cross-Browser-Polyfills). + +## The content area + +The central part of the boilerplate template is pretty much empty. This is +intentional, in order to make the boilerplate suitable for both web page and +web app development. + +### Browser Upgrade Prompt + +The main content area of the boilerplate includes a prompt to install an up to +date browser for users of IE 6/7. If you intended to support IE 6/7, then you +should remove the snippet of code. + +### jQuery CDN for jQuery + +The jQuery CDN version of the jQuery JavaScript library is referenced towards +the bottom of the page. A local fallback of jQuery is included for rare instances +when the CDN version might not be available, and to facilitate offline +development. + +The jQuery CDN version was chosen over other potential candidates +([like Google's Hosted Libraries](https://developers.google.com/speed/libraries/)) +because it's fast ([comparable or faster than Google by some +measures](https://www.cdnperf.com/#jsdelivr,cdnjs,google,yandex,microsoft,jquery,bootstrapcdn/https/90)) +and, (unlike Google's CDN) is available to China's hundreds of millions of internet users. +For many years we [chose](https://github.com/h5bp/html5-boilerplate/issues/1191) +the Google Hosted version over the jQuery CDN because it was available +over HTTPS (the jQuery CDN was not,) and it offered a better chance of +hitting the cache lottery owing to the popularity of the Google CDN. +The first issue is no longer valid and the second is far outweighed by +being able to serve jQuery to Chinese users. + +While the jQuery CDN is a strong default solution your site or application may +require a different configuration. Testing your site with services like +[WebPageTest](https://www.webpagetest.org/) and browser tools like +[PageSpeed Insights](https://developers.google.com/speed/pagespeed/insights/) or +[YSlow](https://developer.yahoo.com/yslow/) will help you examine the real +world performance of your site and can show where you can optimize your specific +site or application. + +### Google Universal Analytics Tracking Code + +Finally, an optimized version of the Google Universal Analytics tracking code is +included.

Welcome!

+ It's a bear, picture it +

The domestic cat[1][2] (Felis catus[2] or Felis silvestris catus[4], informally Felis domesticus[6][7]) is a small, usually furry, domesticated, carnivorous mammal. It is often called the housecat when kept as an indoor pet,[8] or simply the cat when there is no need to distinguish it from other felids and felines. Cats are valued by humans for companionship and ability to hunt vermin and household pests. They are primarily nocturnal.[9]

+

Cats are similar in anatomy to the other felids, with strong, flexible bodies, quick reflexes, sharp retractable claws, and teeth adapted to killing small prey. As crepuscular predators, cats use their acute hearing and ability to see in near darkness to locate prey. Not only can cats hear sounds too faint for human ears, they can also hear sounds higher in frequency than humans can perceive. This is because the usual prey of cats (particularly rodents such as mice) make high frequency noises, so the hearing of the cat has evolved to pinpoint these faint high-pitched sounds. Cats also have a much better sense of smell than humans.

+

Despite being solitary hunters, cats are a social species, and cat communication includes the use of a variety of vocalizations (meowing, purring, trilling, hissing, growling and grunting) as well as pheromones and types of cat-specific body language.[10]
