<h3>Markup not required</h3> |
|
|
155 |
<p>The primary purpose of the Console is to aid in debugging your application. As such, it doesn't make much sense to require your page to include markup for something that is not bound for production.</p> |
|
|
156 |
|
|
|
157 |
<p><em>However</em>, Console is built on the Widget framework, so it can be rendered into a containing element just as any other Widget. We'll do that for the first two Consoles, then for the third we'll call <code>render</code> with no input, allowing the default behavior.</p> |
|
|
158 |
|
|
|
159 |
<p>For the first two cases, we need to set up some markup. We'll throw in some placeholder content for the third.</p> |
