Clearfix needed?

Hello!

I am having trouble with a <p> tag that I am using to control a container with info, and then forcing the text content that comes afterwards to drop down to the next line (below the container).

Webpage link: https://www.leadingpractice.com/about-us/leadership-team/

Here’s the code for that particular context area:

<p style="background-color: #f5f5f5; width: 303px; display: block; float: left; padding: 10px; padding-bottom: 10px; border-bottom-style: solid; border-bottom-width: 1px; border-bottom-color: #003264;"><b>Gert Jansson</b><br />Advisory Board, Northern Europe<br />VP of Enterprise Standards for Northern Europe</p>

<p style="background-color: #f5f5f5; width: 303px; display: block; float: left; padding: 10px; padding-bottom: 10px; margin-right: 10px; margin-bottom: 10px; border-bottom-style: solid; border-bottom-width: 1px; border-bottom-color: #003264;"><b>Yury Orlov</b><br />Advisory Board, Russia<br />CEO of Smart Architects</p>

<h1>Quality Assurance Team</h1>

<p>As a community-driven open source standards concept, we are using a fully integrated continuous improvement approach. Hence, both the practitioner community and the development partners take an active part in the feedback loop to improve, suggest, adding artifacts and contribute to shape new ways of linking different industry requirements as well as how to model them more efficiently.</p>

How can I get the Quality Assurance Team headline to drop down below the grey Yury Orlov container box?

Thanks!
