Hi there,
Please kindly add the CSS code below to X > Launch > Options > CSS:
.flex-direction-nav a.flex-next {
left: auto;
right: 14px;
top: calc(50% - 10px);
}
.flex-direction-nav a.flex-prev {
top: calc(50% - 10px);
}
.flex-direction-nav [class*="x-icon-"].x-icon-chevron-right:before {
content: "";
background: url('https://image.flaticon.com/icons/svg/60/60758.svg') center center no-repeat;
background-size: contain;
display: block;
width: 20px;
height: 30px;
}
.flex-direction-nav [class*="x-icon-"].x-icon-chevron-left:before {
content: "";
background: url('https://image.flaticon.com/icons/svg/60/60758.svg') center center no-repeat;
background-size: contain;
display: block;
width: 20px;
height: 30px;
}
You will need to change the URL of the images with the URL of your images for the arrows and also you can use the width and height properties in the code to fine-tune the case for your image.
Thank you.
