The latest update of Appdev has an issue with iPhone overlapping the text in mobile layouts – for resolutions less than 768px. Pls insert the following custom css in the Custom CSS tab in the theme options panel or in the custom/custom.css file to overcome this issue until the next update –
@media only screen and (max-width: 767px) {
.features-list-alternate .iphone-slider-container, .features-list-alternate .smartphone-slider { margin-top: 0; }
}
