Screenshot showing extra shadow artifact
The following CSS rules cause an additional shadow to be applied around a box that is not accounted for by any of the elements.
<div style="padding:100px 0;
text-shadow:0 0 10px rgba(0,0,0,0.5);">Meet the Team</h1>

NOTE: I cannot reproduce this inside the iOS simulator; it only appears on a physical device (iPhone 6 / iOS 9.3).

When either the text (size position) or the text-shadow change, the artifact changes too. Also it can be clipped out with overflow hidden.
