How to decapitalise 'SOLD OUT' text?

Site URL: https://georgesgorgeousgardens.co.uk

Hi guys,

Is there a way to decapitalise the SOLD OUT text to make it just 'Sold out'? Seems that whatever I put in the custom message box it makes it block capitals, which doesn't really fit in with the styling of the rest of my site.

Thank you.

Add to Home > Design > Custom CSS

/* Sold out text */
.product-mark.sold-out {
    text-transform: capitalize !important;
}

Thank you for your help, the solution worked.
