Theme Horse

I found on your forum this code:

html, body, div, span, applet, object, iframe, h1, h2, h3, h4, h5, h6, p, blockquote, pre, a, abbr, acronym, address, big, cite, code, del, dfn, em, font, ins, kbd, q, s, samp, small, strike, strong, sub, sup, tt, var, dl, dt, dd, ol, ul, li, fieldset, form, label, legend, table, caption, tbody, tfoot, thead, tr, th, td {
	border: 0;
	font-family: helveticaneue;
	font-size: 100%;
	font-style: helveticaneue;
	font-weight: helveticaneue;
	margin: 0;
	outline: 0;
	padding: 0;
	vertical-align: baseline;
}

And now I want to know how I can make the fontsize smaller.
