Hi Duleme

To recreate first set your Joomla Editor to CodeMirror (Site -> Global Configuration -> Default Editor). Navigate to Extensions -> Module Manager -> New -> Custom HTML, set your module position to top-2a and add the following code to the Custom Output..

<img src="http://demo.joomla51.com/0091/images/responsive.png" align="left" style="display:block; margin-top:-130px; position:relative; z-index:999;" />

<h1 style="text-align: right;">A Powerfully Responsive Joomla Template Design</h1>

<h4 style="text-align: right;">Adapts beautifully to all your mobile devices </h4>

..where margin-top:-130px; is the vertical displacement of the image. The effect works best with PNG images with a transparent background.
