Sorry for the noobie and stupid question, but I know only a bit about css and I don't know how to style my site. Here is my code:

HTML (Twig) :

<div class="wrap">
    <div>
        <img class="birthday" src="http://www.clker.com/cliparts/1/d/a/6/11970917161615154558carlitos_Balloons.svg.med.png">
            <div class="try"> 
               This friends have brithday today: 
               {% for bd in birthdays %}

               <p>
                   <a href="{{ path('friend_id', {'id': bd.id}) }}">{{ bd.name }}</a>
                      <span class="years">
                         ({{ bd.years }} years)
                       </span>
               </p>

               {% endfor %}

            </div>

    </div>
</div>

CSS:

body {
    background-color: #FFFFF1;
    text-align: center;
    font-size: 17px;
    font-family: Tahoma, Geneva, sans-serif;  
}

p {
    margin: 10px;
}

a {
    text-decoration: none;
    color: #6a9211;
}

a:hover {
    text-decoration: underline;
}

.wrap {
    width: 700px;
    margin: auto;
}

.birthday {
    width: 49px;
    height: 80px;
    float: left;
    margin-left: 150px;
    display: block;  
}

.try {
    display: block;
    margin-right: 150px;
    margin-bottom: 50px;
}

.years {
    font-size: 12px;
}

And this is what I get. The thing I want to fix is Maria and Peter to be display under Anna and John, all of them 4 centered under the label This friends have birthday today:. I know that it's because of the image, but I don't know how to make it look fine. :(

Please help! Thanks in advance!
