You need to remove this width setting under div#tagline p from Hearthstone.css

div#tagline p
{
width: 828px; // remove this because it's positioned absolutely.
}

How about setting the body width to 100% instead of 828px in the css file. Or a hack like :

overflow:hidden;

in css always work.

add in stylesheet under body tag 'overflow-x: hidden;'

body {
    overflow-x: hidden;
}
