 ## Packaging games
 
-The web is the first and the best choice for HTML games, but if you want to reach a broader audience and distribute your game in a closed ecosystem, you still can do that by packaging it. The good thing is that you don't need a few separate teams working on the same game for different platforms — you can build it once and use tools like [Phonegap](https://phonegap.com/) to package the game for native stores. The resulting packages are usually pretty reliable, but you should still test them and be on the lookout for small issues or bugs to fix.

You can also check out the tutorial about [using the Leap Motion plugin for Kiwi.js](https://webdesign.tutsplus.com/add-motion-control-to-a-kiwijs-game-with-the-leap-motion-controller--cms-20455t), or the case study of [building a web game with Leap Motion and Pixi.js](https://arstechnica.com/information-technology/2014/04/building-a-gesture-controlled-web-game-with-leap-motion/).

If all else fails, there's also a [gallery of working examples](https://leap2.ultraleap.com/downloads/) you can look at.

 To get the Leap Motion working on your computer you have to first install it by following the steps at [docs.ultraleap.com](https://docs.ultraleap.com/hand-tracking/getting-started.html#installation-guides). When everything is installed and the controller is connected to your computer we can proceed with implementing support in our [little demo](https://github.com/end3r/JavaScript-Game-Controls/). First, we add a `<script>` tag with the `url` pointing at [this file](https://js.leapmotion.com/leap-0.6.4.min.js), and add `<div id="output"></div>` just before the closing `</body>` tag for outputting diagnostic information.
 
 We will need a few helper variables for our code to work — one for the purpose of calculating the degrees from radians, two for holding the horizontal and vertical amount of degrees our hand is leaning above the controller, one for the threshold of that lean, and one for the state of our hand's grab status. We next add these lines after all the event listeners for keyboard and mouse, but before the `draw` method:

We'll return to our simple absolutely-positioned tabbed interface (see [Hiding things](/en-US/docs/Learn/Accessibility/CSS_and_JavaScript#hiding_things) in our CSS and JavaScript accessibility article), which you can find at [Tabbed info box example](https://mdn.github.io/learning-area/css/css-layout/practical-positioning-examples/info-box.html) (see [source code](https://github.com/mdn/learning-area/blob/main/css/css-layout/practical-positioning-examples/info-box.html)).

 This example as-is works fine in terms of keyboard accessibility — you can happily tab between the different tabs and select them to show the tab contents. It is also fairly accessible too — you can scroll through the content and use the headings to navigate, even if you can't see what is happening on screen. It is however not that obvious what the content is — a screen reader currently reports the content as a list of links, and some content with three headings. It doesn't give you any idea of what the relationship is between the content. Giving the user more clues as to the structure of the content is always good.

This article provides an overview how IMSC is related to these other subtitle standards, and explains the differences between the versions of IMSC.
 
 ## IMSC spec genealogy
 
 [TTML Profiles for Internet Media Subtitles and Captions](https://www.w3.org/TR/ttml-imsc/all/) (or IMSC) is a constrained version of the Timed Text Markup Language for worldwide subtitles and captions family of specifications.
 
-IMSC was designed to be a practical application of SMPTE-TT ([SMPTE ST 2052-1](https://ieeexplore.ieee.org/document/7291854/)), which is designated as a safe-harbor format by the [FCC](https://www.law.cornell.edu/cfr/text/47/79.103). As a result, most SMPTE-TT documents should render correctly using IMSC renderers (see [the limitations](https://www.w3.org/TR/ttml-imsc1.0.1/#smpte-tt-smpte-st-2052-1)), and the conversion guidelines from CTA 608/708 to SMPTE-TT ([SMPTE RP 2052-10](https://ieeexplore.ieee.org/document/7289645/) and [SMPTE RP 2052-11](https://ieeexplore.ieee.org/document/7290363/)) are also applicable to IMSC.

 IMSC is also a syntactic superset of both [SDP-US](https://www.w3.org/TR/ttml10-sdp-us/) and [EBU-TT-D](https://tech.ebu.ch/publications/tech3380), such that documents that conform to either of these two formats are valid IMSC documents and can be rendered by IMSC renderers — see [Compatibility with other TTML-based specifications](https://www.w3.org/TR/2018/REC-ttml-imsc1.0.1-20180424/#interop-examples) for more details.

This allows trackers to get around third-party cookies being blocked.

This means the tracker is loaded as a first party, and can associate tracking data with the identifiers they have stored in their first-party cookies before forwarding you to the retailer.
 
 Tracking data can be used to build a profile of a user and their interests and preferences, which is usually bad and can be annoying to various degrees. For example:
