Prevent Page Scrolling for iOS Browser
Sometimes, a page shows only one fullscreen section. The page cannot be scrolled except on the iOS device. Please try to add(replace 475) the Custom CSS to fix the bug on the iOS:
@media (orientation: portrait) {
.page-id-375 #wrap { max-height: var(--get-win-height); overflow-y: hidden; min-height: 0; }
.page-id-375 .bm-wrap > .module-inside { min-height:0!important; height: var(--get-win-height, 100vh); overflow-y: hidden; }
.page-id-375 .slider-mod-wrap,
.page-id-375 .owl-carousel,
.page-id-375 .bm-builder .module .slider-mod-wrap.slider-style2 .bm-tab-slider { max-height: var(--get-win-height); }
}
Note: 375 is the unique page ID, please replace it as your page’s ID, refer to how to find the page ID
