It works like this:

}
h4:after {
    content:"\a";
    white-space: pre;
}

Answer 2

You can use ::after to create a 0px-height block after the <h4>, which effectively moves anything after the <h4> to the next line:

h4 {
  display: inline;
}
h4::after {
  content: "";
  display: block;
}

<ul>
  <li>
    Text, text, text, text, text. <h4>Sub header</h4>
    Text, text, text, text, text.
  </li>
</ul>

Answer 3

Try

h4{ display:block;}

in your css
