One tag indenting on Chrome but not Firefox. (can't understand why it is indenting)

I've just spent too long updating my site: http://knowace.com. Reviewing in Chrome, I've noticed that my headers are inset ten pixels farther than the content below them. I can't see why. The styles are essentially the same settings. The problem isn't evident in Firefox. If anyone has an idea what I can do about this, I'd appreciate it.

.textHeading {
font-size:14px;
font-weight:bold;
text-align:left;
margin-top:5px;
width: 500px;
border-bottom:1px; (I added this only because it was on the style below.)
display:block;
}
.textCopy3{
font-weight:100;

Diferent Browsers, different crap

Hi,

I am new in that. I'm trying to perform my first web page with dreamviwer. After adjusting the padding and everything, I see that depending on the browser I use for see the webpage the links change their position and some special carachters in spanish are not shown properly. (in dreamviwer look fine)

Sorry if this topyc has been already discussed in this forum. I've not found it.

Thanks in advance,

Dapergu

my .css

h1 {
	font-size: 8em;
	margin-bottom: 0em;
	margin-left: 0.5em;
	margin-top: 0.25em;
	padding:0;
	font-family: algerian;

Browser compatibility RIM (blackberry) and youtube embed

Anybody run into RIM (blackberry) not displaying youtube embeds?
Also, my video styles don't seem to keep their floats. Simple three-column layout.
Thanks in advance!

Lower edges not lining up across browsers...

This is probably an easy fix.. or a known issue, but I can't get the bottom of my lower boxes to match up across browsers. It only matches up in Firefox, not Chrome or Safari.
