How to change amout font size in /index.php?main_page=index&cPath=33

Hi

I want to change font size in /index.php?main_page=index&cPath=33 page which is a catalogue listing page.

Prices are listed without the css class like this. Not sure where the this price is coming from ( which zencart php file)

..... and where it says ... more info

You can see it here http://www.silkaurora.com.au/index.php?main_page=index&cPath=33

Can anyone please give suggestion as to how to style this?

OK I found the file modules/product_listing.php

How do I wrap style tag around code where it displays the price?

===========================

blah blah

   break;
    case 'PRODUCT_LIST_PRICE':
    $lc_price = zen_get_products_display_price($listing->fields['products_id']) . '<br />';
    $lc_align = 'right';
    $lc_text =  $lc_price;

    // more info in place of buy now

=================================

UPDATE!! I did it

I forgot the same file was in my template folder. Once changed it worked.

Ok I tried this but it did not work

    $lc_text = '<h2 class="centerBoxHeading">'. $lc_price . '</h2>';

which references to CSS
h2.centerBoxHeading {color:#000;
font-size:17px;
line-height:32px;
text-transform:uppercase;
font-weight:normal;
font-family: 'Oswald', sans-serif;
margin-bottom:10px;}

====== original code on line 96 of includes/modules/product_listing.php =============

    case 'PRODUCT_LIST_PRICE':
    $lc_price = zen_get_products_display_price($listing->fields['products_id']) . '<br />';
    $lc_align = 'right';

// original code >> $lc_text = $lc_price;
$lc_text = '<h2 class="centerBoxHeading">'. $lc_price . '</h2>';
