I have copied the instructions, I have tried several ways, but nothing works.
Wrap with a div
Nicely done! As before, let's group this large feature with two divs to stay organized, like this:
<h1>Find a place to stay.</h1>
<p>Rent from people in over 34,000 cities and 192 countries.</p>
<div class="jumbotron">..</div> groups the elements into the large feature section of the web page. The inner
<div class="container">..</div> element wraps the contents in a container. We'll use both classes in the next section to style the large feature.
Wrap the h1 and p elements with two divs, like in the example above. Give the outer div a class="jumbotron" and the inner div a class="container".
