I am trying to make a instagram like website I need some help with positioning cards in CSS. Because when ever they are added they get put underneath one and other. I have tried to play with positing in CSS and can't get the perfect fit.

               <div class="card-content">
                 <p>I am a very simple card. I am good at containing small bits of information.
                 I am convenient because I require little markup to use effectively.</p>
