Why is my page so wide?

Take a look at my website using Firefox or Chrome : BehineHost.

I just set up and configured "Nivo Slider". Before that all was going well, but now if you open the page with Firefox or Chrome, you'll see a l开发者_运维知识库arge horizontal scrollbar at the bottom of the browser.

I did a lot of checks but found nothing...

How can I fix it?

Text-indent : -9999px, that's why.

Class that cause it :

.nivo-controlNav a {
    background: url("images/bullets.png") no-repeat scroll 0 0 transparent;
    border: 0 none;
    cursor: pointer;
    display: block;
    float: right;
    height: 19px;
    margin-right: 15px;
    margin-top: 30%;
    opacity: 0.5;
    position: relative;
    text-indent: -9999px;
    width: 17px;
    z-index: 9;
}

If you had looked more carefully, you would have seen the 1 2 3 on the far right.
