Line break on mobile phone only
<p>I have a phone number on a website. It looks good on a laptop, but on a mobile device half of the number jumps to the next line. It doesn't look good. </p>

<p>So how can I create a line break that will only work on a mobile device sized screen?</p>

<p>I am not very experienced in coding, so please be specific :) Thanks a lot for any help! </p>
