About & FAQ

Visit the About & FAQ section to know more about CrossBrowdy.


To include it in your project and start using it, the most common way to download CrossBrowdy for production is through the Download section from the official web site.

You can also download CrossBrowdy from the GitHub repository directly. Just download the whole content of the dist/ folder.

Alternatively, from the command line (shell), you can also use one of the following commands to download CrossBrowdy while you are in your project folder:

Using Yarn:

yarn add crossbrowdy 

Using npm:

npm i crossbrowdy 

Using pnpm:

pnpm i crossbrowdy 

Using Bower:

bower install jalbam/crossbrowdy --save 

Note: Yarn, npm, pnpm and Bower will also download the API documentation.


Instead of downloading CrossBrowdy, you can hotlink it by directly pointing to a version available online. For instance this way you will be pointing to the last version:

<script src="" type="text/javascript" language="javascript"></script><!-- "type" and "language" parameters for legacy clients. -->

You can find a list of some CDN providers in the Download section of the official web site. Thanks to them, you will be able to always use the last up-to-date version or even to point to a specific version you may prefer.

Have in mind that including the CrossBrowdy main file from a CDN provider should never be done for production. This hotlinking method can be useful just for testing purposes. Some features might not work properly using this way and availability cannot be always guaranteed.

Getting started

Just include the main JavaScript file, which is called CrossBrowdy.js, in your HTML file. The recommended place to include this main JavaScript file is inside the head section (inside the <head> tag) of the document.

Here you have a simple example:

<!DOCTYPE html>
		<meta http-equiv="content-type" content="text/html; charset=utf-8" />
		<title>My first CrossBrowdy project!</title>
		<script src="CrossBrowdy/CrossBrowdy.js" type="text/javascript" language="javascript"></script><!-- "type" and "language" parameters for legacy clients. -->
		<script type="text/javascript" language="javascript">
			CB_init(main); //It will call the "main" function when ready.

			//This function will be called when CrossBrowdy is ready:
			function main()
				//Now, you can start using CrossBrowdy here...
				CB_console("CrossBrowdy started!");
		// -->
		<!-- The "CB_console" element will be used automatically in the case that the client does not support console: -->
		<div id="CB_console" style="display:none; visibility:hidden; overflow:scroll;">
			<span style="font-weight:bold;">Console:</span><br />
