I am trying to add a break in the definition list but it says that it is not allowed as child element in dl. How do I put a break without using br in HTML?

```
<dl>
  <dt>Activities</dt>
  <dd>- Trekking</dd>
  <dd>- Rappelling</dd>
  <dd>- Kayaking</dd>
  <dd>- Rock Climbing</dd>
  <dd>- Cycling</dd>
  <dt>Hobbies</dt>
  <dd>- Dancing</dd>
  <dd>- Listening to Music</dd>
  <dd>- Reading Novels</dd>
  <dd>- Android Programming</dd>
</dl>

```

My CSS code:

```
dl {
  margin-top: 0;
  margin-bottom: 21px;
}
dt, dd {
  line-height: 1.42857143;
}
dt {
  font-weight: bold;
}
dd {
  margin-left: 0;
}

```
