Why doesn't the html tags work for wordpress?

Maybe you changed the width of your h1? ... it won't be centred if it's width is not that of the width of the page?

Get chrome, view your page, press F12, look up the elements and check their css, simple.
 


gotta be in the css like everyone said but if you don't want to go in there maybe just try a normal <center><h1>poop</h1></center> around it which should get it to go center. I've had the align center atr within the h1 not work for me once before as well a while ago.

the color and all that should def be coming from the css though.
