Cek the icons banner under download now. If I use the following code:

<div class="row">
      <div class="icons-area text-center">
        <center></center><img class="img-responsive" src="<?php base_url() ?>public/images/icons.jpg" style="margin-left: auto; margin-right: auto; height: 200px;" alt="AWS"></center>

with the style on pc it looks good but on handphone it start being cramp. I have to delete the whole style to make it looks on cell phone, but on pc it looks too big. I wonder how to make it looks good both on handphone and pc?
