wordpress how to align H2 tag?

Hi. I’m having trouble trying to align the H2 tag. Tried to use <h2 style=”text-align: center;”>H2 tag here</h2> – but it didn’t work. H2 tag still showing up on left side of the page http://frugalmint.com/how-to-save/accumulated-wisdom-easy-tips-to-save-money/

Will be very appreciated for advice.
