Hello @Jayprospr

You can try this code: it will be helpful to you

Go to the Online Store->Theme->Edit code->Assets->timber.scss>Add this code at the bottom.

.grid__item {
    text-align: center !important;
}
.single-option-selector, .quantity-selector {
    margin: 0 auto;
}
.btn--wide, .product-form--wide .shopify-payment-button__button, .product-form--wide .shopify-payment-button__more-options {
    margin: 8px auto;
}

Thank you so much it worked perfectly! Could you help me with one last thing, any way I can add the search icon, and account icon next to the cart on the right side?
