I am noticing that line 43 in the HTML code of the following random quote generator contains an opening div without its closing div. The code runs as intended. In what situations can we use stand-alone opening divs? Thank you for the help.
The code in question is
<div class="ripples buttonRipples"> in
<button class="btn btn-primary btn-lg buttonBlue" ng-click="randomQuote($event)">Random<div class="ripples buttonRipples"><span class="ripplesCircle"></span></button>
</div><!-- End of Random Button -->
