Inserting span into php code

[Sp0cK]

This is probably the lamest question you will see today, but for me the hardest to answer:

sprintf( __( '%1$s起', 'woocommerce' )

I would like to style the character 起 with a span sort of like this:

'%1$s'<span style='font-size: 10px;'起'</span>, 'woocommerce' )

I'm pretty sure I've got my quotes all wrong in this example. 

 

How do I do this the correct way if possible at all? It's on a live site so i can't play around with it too much...

 

Thanks!

 

The full line is:

$saleprice = $prices[0] !== $prices[1] ? sprintf( __( '%1$s起', 'woocommerce' ), wc_price( $prices[0] ) ) : wc_price( $prices[0] );

$saleprice is being outputted into the HTML somewhere. That's where you should add the span. But first look to make sure there isn't already a way to style the element as it currently exists on the page.
