Hello and welcome to stackoverflow.
Thank you for providing a link to a fiddle, but it is essential that you also include the relevant code here.
In response to your question, one quick solution would be to enclose the label
s within a container (form
perhaps) and apply flexbox styling to this container (you may even remove your existing styles):
form {display: flex; flex-flow: column; /* remove this if you want it horizontal */ }
<div class="form-group">
<p>Which superpower would you like to have?
<span class="clue">(Check all that apply)</span></p>
<form>
<label>
<input
name="superpower"
type="checkbox"
value="mind-read"
class="input-checkbox"
>Mind Reading
</label>
<label>
<input
name="superpower"
type="checkbox"
value="invisibility"
class="input-checkbox"
>Invisibility
</label>
<label>
<input
name="superpower"
type="checkbox"
value="teleportation"
