The full HTML/CSS is as follows:
// This is the box that shows up at the very top, defined as a "notification alert"
<div class="ns-box ns-growl ns-effect-slide-center ns-type-notice ns-show">
<div class="ns-box-inner">
<span class="thin" style="line-height: 35px; font-size:24px" color="#4A4A4A">[TITLE]</span>
<br><span class="light" style="font-size:28px;line-height: 30px;">[MESSAGE]</span>
</div>
</div>
// This is the pop-up in the middle of the screen, defined as a regular "alert"
<div class="ns-alert ns-growl ns-effect-flip ns-type-notice ns-show">
<div class="ns-box-inner">
<span class="light" style="line-height: 35px; font-size:30px" color="#4A4A4A">[TITLE]</span>
<br><span class="thin" style="font-size:22px;line-height: 30px;">[MESSAGE]</span>
