I do not see a ticker on your site. Please direct me to a page that contains it and I will try to help you out with some custom css.
Just to be clear for anyone running into similar issues... these issues are CSS styling issues that are completely detached from Ditty News Ticker and it's code. There is only enough CSS added to Ditty News Ticker for it to function correctly. Other than that all element styles will use whatever your theme has setup.
The styling of of html elements is dependent on your particular theme... if your h1 tags in your theme have a margin-top of 30px, then the h1 elements that show up in the tickers will have a margin-top of 30px. If you need particular elements to have a different style within the ticker then you must add custom CSS on the News Ticker > Settings page (or anywhere else you can add custom css) to override your theme's CSS.
