Good evening. I would like to make the module in the position 'top-b' of the demo. What extension should I use?

The top-b modules are simple html module with this content include:

<div style="text-align: center;">
<span class="ico">Q</span>
<h4>Responsive Design</h4>
<p>A fully responsive layout that adapts perfectly for all device resolutions.</p>
</div>

Icons config can be found here: > Pictograms
demo.joomlaplates.com/jp_work/theme-features/typography.html

Problem solved.
