Wordpress theme styling

My wordpress theme has 2 different styles for header text in the banner area of each page. This can only be changed via the CSS but I can't work out how to do it.

The homepage text is larger and has no drop-shadow. I would like to replicate this across all pages on the site. The homepage can be viewed here.

Other pages look like this

Any advice on how to alter this would be much appreciated.

thanks
