How to change backround color of item title only

I understand by changing background color under h1 changes its color but how do I make it so that it only changes an item titles color (on the products information page) and not the main page section where it says "Congratulations! you have successfully installed..." which is located in includes/languages/ENGLISH/CUSTOM/index.php. I would like that main page section to be transparent.

Thanks,

Reading the posting tips would have told you that more information is needed to really help. IF you are wanting to make a particular category or product's page look different from the others, take a look at the CSS_read_me.txt in the css folder of template_default.

Unless your template seriously messes with the page source code (which Template Monster and some others often do), you can limit the <h1> background styling to the product info page with

#productinfoBody h1 {what: ever;}

Thanks for you help guys.
