Hi,
the shortcode is merely to style text or a section a specific way, it doesn’t have any deeper meaning.
For example this code
[impact_text include_button="yes" button_style="standard" title="Buy now" href="/features/" color="accent" size="normal" type="roundedarrow" target="_self" position="cta_align_right" alt_background="alt-seven" el_class="mb0 mt0 bt0" width="1/1" el_position="first last"]
<h2>Neighborhood: A clean, responsive & retina-ready multipurpose eCommerce WordPress theme.</h2>
[/impact_text]
on our homepage seven http://neighborhood.swiftideas.net/home/home-example-seven/ creates the bar with the border and the button. You can use the shortcode to style your content 🙂
Let me know if you have further questions!
All the best
