Add this code to the Custom CSS field on the Style tab of your Pricing Table widget’s settings:
@media (width <= 640px) {
.global-styles,
.eapps-pricing-table {
width: 100%;
}
.eapps-pricing-table-inner {
width: 100%;
overflow: hidden;
}
.eapps-pricing-table-columns-container {
flex-direction: row !important;
align-items: unset !important;
justify-content: flex-start !important;
width: 100%;
padding: 1px 0;
overflow: auto;
}
.eapps-pricing-table-column {
min-width: 275px;
}
}
Note: The min-width should be adjusted depending on the number of columns
