The problem is caused by the docked top banner. That is not compatible with the CSS that moves the content under the masthead, it causes the page to shudder at a certain point when scrolling. You’ll notice that on the demo website the demo App Landing Page doesn’t have a docked top banner, and the reason for that is because it conflicts with the custom CSS that restyles the masthead.
After I first posted the CSS in this topic three months ago Andy has changed that CSS on the demo website to this…
@media screen and (min-width: 768px) {
#masthead {
background-color: transparent !important;
position: absolute !important;
width: 100% !important;
-webkit-box-shadow: none !important;
-moz-box-shadow: none !important;
box-shadow: none !important;
}
#masthead .site-title a.logo-image {
margin: -15px 0 0;
}
#DockedNavPlaceholder, #DockedNavPlaceholder[style] {
display: none !important;
}
}
In the original custom CSS it was the .dockedNav #masthead
styling that was causing the problem with the iPad not displaying the transparent masthead, instead it always displayed the docked top banner. If you use the above CSS instead you should get the transparent masthead on an iPad. But alas, the price you pay for this is no docked top banner.
