Hi @nicholasdent
It seems like custom CSS is creating issue, this can be fixed with some custom CSS. Under Customize > Additional CSS, you can add the following code:
/* Change product description font size on checkout page */
.woocommerce-checkout .nectar-split-heading h1 {
font-size: 22px;
line-height: normal;
}
.woocommerce-checkout .wc-block-components-product-metadata__description .row_col_wrap_12.col.span_12.dark.left {
min-width: 100%;
display: inline-block;
}
.woocommerce-checkout .wc-block-components-product-metadata__description .row_col_wrap_12 .vc_col-sm-6.wpb_column.column_container {
width: 100%;
padding: 0px !important;
}
If you’d like to learn more about CSS, I highly recommend using the free tutorials at w3schools. Here, you can find the basics of selectors (how to target the right element on the page), and properties (how to change the element on the page).
