I have a responsive popup that I've created and I want to show an image in the center of the div. However, when I resize the screen width, the image remains pinned at the top of the div.

<div class="row">
<div class="five columns">
<img class="imga" src="images/warning.png">
</div>
<div class="seven columns">
<p style="color:#e57a2a; font-size: 150%; text-align: center; line-height: 1.1;"><b> We apologize, but home delivery service is currently not available in this area </b></p>
<p style="color:#20540D; font-size: 120%; text-align: center; line-height: 1.1;"> We invite you to place your order for store pickup at our restaurants</p>
<center><button style="background-color:#e57a2a;color:white; border:none; height:35px;">order now </button></center>
</div>
</div>
.imga{
max-width:100%;
position: relative;
margin:auto;"
}
