Worth noting

1. Elements with the slide-down directive cannot have vertical padding applied to them. If this is required just wrap another div inside this element and apply padding to that div.
2. Direct children of the element with the slide-down directive should be styled as a block (or flex), if you need to float the children in any way please wrap another element inside it and float its children.

<!-- No vertical padding allowed here -->
<div [slide-down]="contentVisible">
	
	<!-- Wrapped div with padding -->
	<div style="padding: 20px 0;" class="clearfix">
	
		<!-- Floated children not direct children -->
		<div style="float: left;">...</div>
		...
	</div>
</div>
