Changing Alignment of Jumbo Headline

I am trying to figure out if I can change the alignment of the jumbo headline and accompanying text to be in line with the elements below it. This is the website: centuryamerica.org. I’d like for the jumbo headline to look exactly the same , but just centered over the widget that is on the left. Likewise, I would like the accompanying text for the jumbo headline to be centered over the content.

Is there an easy way to do this? I’ve tried messing with margins, padding, etc. and nothing seems to be working so far (though I’ll admit my CSS knowledge is not extensive). Any tips appreciated! Thanks!
