Adding the word From before pricing in Woo Commerce

Hi – you gave me some code so that the From would appear before the prices listed for products in Woo Commerce.

.single-product .summary p.price:before {
content: “From: “;
}

span.price:before {
content: ‘From: ‘;
}

Sorry – that code probably doesn’t display correctly – can’t remember the tags to use to enclose a piece of code …

It works great – only thing is I only need the word ‘From’ to appear for products with variable prices not for all products – is that possible?

Thanks!
