If you just add a single button the a div header element like this

```html

Test Button

```

The result is a thin blue line where the header should be. If you manually set the CSS of the header to a value, you will see the header and the button as you expected. However if you do the following:

```html

Test Button

```

Everything works as expected. It appears the header requires an H element to be formatted correctly.
