<div><h2 id="description">Description</h2>
<div class="description"><div class="ng-directive-page ng-directive-ngcloak-page"><p>The <code>ngCloak</code> directive is used to prevent the Angular html template from being briefly
displayed by the browser in its raw (uncompiled) form while your application is loading. Use this
directive to avoid the undesirable flicker effect caused by the html template display.</p>
<p>The directive can be applied to the <code>&lt;body&gt;</code> element, but the preferred usage is to apply
multiple <code>ngCloak</code> directives to small portions of the page to permit progressive rendering
of the browser view.</p>
<p><code>ngCloak</code> works in cooperation with the following css rule embedded within <code>angular.js</code> and
<code>angular.min.js</code>.
For CSP mode please add <code>angular-csp.css</code> to your html file (see <a href="api/ng.directive:ngCsp"><code>ngCsp</code></a>).</p>
<pre class="prettyprint linenums">
[ng\:cloak], [ng-cloak], [data-ng-cloak], [x-ng-cloak], .ng-cloak, .x-ng-cloak {
  display: none !important;
}
</pre>
<p>When this css rule is loaded by the browser, all html elements (including their children) that
are tagged with the <code>ngCloak</code> directive are hidden. When Angular encounters this directive
during the compilation of the template it deletes the <code>ngCloak</code> element attribute, making
the compiled element visible.</p>
<p>For the best result, the <code>angular.js</code> script must be loaded in the head section of the html
document; alternatively, the css rule above must be included in the external stylesheet of the
application.</p>
<p>Legacy browsers, like IE7, do not provide attribute selector support (added in CSS 2.1) so they
cannot match the <code>[ng\:cloak]</code> selector. To work around this limitation, you must add the css
class <code>ng-cloak</code> in addition to the <code>ngCloak</code> directive as shown in the example below.</p>
