Time for action—determining the client's rendering engine and version

We're going to check what rendering engine you're using. If you have several browsers installed in your work station, try the same script in all of them:

  1. For the markup, you can use the following:

    <body>
<div id="browser-info">
<p>The rendering engine you're using is: </p>
<p>The rendering engine's version is: </p>
</div>
</body>

  2. Open your HTML document in a browser to preview your work. You should see the following figure (it shouldn't have the rendering engine information yet):

  3. We'll get information about the browser engine name and version using Browser.Engine.name and Browser.Engine.version, and then assign them to the variables browserEngine and browserEngineVersion. If for some reason we can't determine the values, we assign them values "Unknown" by using || (which means "or"). To do this write:

    var browserEngine = Browser.Engine.name || "Unknown";
var browserEngineVersion...
