I have position: fixed navigation bar at the very bottom of a page on mobile devices / sizes. The nav bar itself has an overflow container where the user can scroll to the right to see additional links (this is a design request and in my opinion a poor user experience, but that's my 2 cents).
The issue I've been seeing when testing on iOS devices is that the scrolling / any link clicking is not available when the top / bottom native browser elements are not on screen. In other words, when those elements auto-hide, the fixed behavior does not work at all. I've created a fiddle below and also included a snippet of the pertinent code under that, in case there's any issues viewing the fiddle on iOS properly:

</div>I've tried some alternative methods, such as -webkit-overflow-scrolling with no luck. I have a feeling this issue is unrelated. Seems to not even register that area of the screen without being pushed up by the native bottom bar on iOS.
Any and all assistance is much appreciated. Just running out of ideas to try on my own. I'm hoping to accomplish this with a minimum of JavaScript, but I'm not at all opposed. Thanks for your help!
Alright, I was able to resolve the issue (which is kind of a weird one). For some reason, having the nav fixed to the very bottom seemed to be the issue. To fix this, I added additional space using the bottom property and added a pseudo-element to fill in the gap. Then, increased the height of the link elements inside the scroll container. Here's the updated code:
.sticky-nav {
position: fixed;
width: 100%;
padding-top: 10px;
bottom: 10px;
left: 0;
z-index: 90;
background-color: #ddd;
border-top: 1px solid #f8f8f8;
}
.sticky-nav:after {
content: "";
position: absolute;
width: 100%;
height: 10px;
bottom: -10px;
left: 0;
background-color: #ddd;
}
.sticky-nav-inner {
display: -webkit-flex;
display: flex;
align-items: center;
justify-content: space-between;
width: 90%;
height: 57px;
max-width: 1200px;
margin: 0 auto;
z-index: 0;
}
.sticky-nav-menu {
display: inline-block;
white-space: nowrap;
height: 100%;
padding-right: 25px;
margin: 0;
}
.sticky-nav-menu li {
display: inline-block;
white-space: nowrap;
height: 100%;
}
.sticky-nav-menu li a {
display: inline-block;
height: 100%;
padding-top: 20px;
padding-right: 25px;
}
.sticky-nav-overflow {
width: calc(100% - 100px);
height: 100%;
margin-right: 2%;
overflow-x: scroll;
}
.sticky-nav-mobile {
padding-left: 1%;
z-index: 1;
