Text Wrap for Sub Labels

I have some text as a "sub label" which I need to text wrap. I tried using </br> which didn't work. Please advise.

Label with issue is "Length of Work"

Hello,

You may inject the following CSS code to wrap all the sub-labels:

.form-sub-label {

  white-space: normal !important;

}

Please let us know if this helps
