please how do someone make the upper part of a web look different from the main body

Answer 1

What/how "different" means here? please come clear with the question.

And please specify any of relevant web development language in tags rather than '<h1>' ☝

Answer 2

You can create separate sections with the use of a <div> tags to indicate navigation, header, and footer.

<div id="nav"> <div class="header"> <div id="footer">

The new way is to use the Semantic elements. <nav> <main> <section> <article> <aside>

Then you style each tag with css.
