How to change the text formating for Featured Content?

My current text formatting in my Featured Content looks like this: <h3>Silversea Silver Whisperer Cruise Jan 5 – May 22, 2022 “The Tale of Tales” World Cruise 2022 Itinerary: 69 PORTS, 32 COUNTRIES The Tale of Tales 2022 is an extraordinary North-South World Cruise spanning parallels 65°S to 65°N, from Antarctica all the way up to Iceland. We will see the world like never before experiencing a stunning range of cultures, climates and environments in one fantastic journey.</h3> How can I change it to look like this: <header class="entry-header"> <h2 class="entry-title">Silversea Silver Whisperer Cruise Jan 5 – May 22, 2022</h2> </header> <div class="entry-content"> <h2>“The Tale of Tales” World Cruise 2022</h2> Itinerary: 69 PORTS, 32 COUNTRIES The Tale of Tales 2022 is an extraordinary North-South World Cruise spanning parallels 65°S to 65°N, from Antarctica all the way up to Iceland. We will see the world like never before experiencing a stunning range of cultures, climates and environments in one fantastic journey. I do not see the formatting tools like in this post or in New Posts. </div>
