How can I add 20px margin only to divs on the left hand side (flex) : <p>The divs are using flex &amp; flex-wrap, and I only want to apply margin-right to the divs on the left hand side as when clicked the border is pushed up against the divs on the right hand side. Any ideas how to achieve this?</p>
