You have created a form with two input boxes, but you want them to appear on separate lines. Which tagged do you use?

To display the input boxes on separate lines, you can use the <br> tag after each input box. This will create a line break and move the second input box to the next line.

For example:
```
<form>
<label for="input1">Input 1:</label>
<input type="text" id="input1" name="input1"><br>

<label for="input2">Input 2:</label>
<input type="text" id="input2" name="input2"><br>
</form>
```

This will display the two input boxes on separate lines.
