Bootstrap Wordwrap issue on Mobile - css

Question

I have a label (#linkDiv) which turns into a button once 'unlocked.' While as a label, the text is longer than the button, so it needs to wrap. I already did white-space:normal; word-wrap: break-word; word-break: normal;
That works for wide and medium screens, but when testing on mobile screen sizes, the line awkwardly wraps the whole label to the next line.
