Header and Subheader overlaying content

Within my index.html file I have specified the following

Header

Subheader

        <p>instructions go here</p>

Obviously there is more code after this but the issue is the Header and Subheader are overlaying the content. Any thoughts?

One day I’ll learn how to use this forum…Here is the code snip

"

Header




Subheader


        <p>instructions go here</p>"

since I clearly don’t know what I’m doing how do I delete this and include code snip
