Hi @Timito ,
You can use the following CSS to fit size chart pop-up within screen and add scroll bars:
.show-pop-up {
z-index: 9999;
}
.pop-up-content {
max-width: 90%;
max-height: 90%;
overflow: auto;
}
Also, you may consider transposing your size chart tables (switch columns into rows and rows into columns), so that will not require horizontal scroll.
Thanks!
