Hi, ajrenk.
There is no slider in the skin 3 demo content, the header is a top graphic, 990 pixels by 470 pixels. This is roughly what that demo content uses in the content area for the top graphic:
[one_half]
<h1 style="font-size:42px; color:#fff; margin-bottom:.3em;">Top Heading</h1>
<h2>All that white text under the top heading</h2>
<h1 style="float: left; margin: 7px 20px 0 0; color: #FDE074;">Don't wait, order now!</h1>
<div style="float: left;">[button_link style="impactBtn" url="#"]I WANT IT![/button_link]</div>
[/one_half]

You may need to play with margins to get it to look exactly the way you want.
