Hi @leonee ,

This is Kate from PageFly - Landing page builder, I’d like to suggest this idea:
Step 1: Go to Online Store->Theme->Edit code
Step 2: Asset->/theme.css->paste below code at the bottom of the file:

.product-info,
.product-info__quantity-selector .form-control,
#vitals-countdown-holder .cntr-align-left {
    text-align: center !important;
    
}
.product-info__quantity-selector .block-label {
    margin-left: auto !important;
    margin-right: auto !important;
}
.vtl-pr-review-stars-snippet,
.rating-with-text,
.variant-picker__option-info,
.variant-picker__option-values {
    justify-content:  center !important;
}

I hope it would help you
