Hello, I am using the latest version wordpress and the twenty twelve theme. I have a child theme set up, my website is http://www.cryptorushnews.com. The following add shows almost perfectly in google chrome but on my android Samsung Charge it overlaps the header logo image and makes for a very messy page.
CSS
/*Place ad banner to the right and add top margin*/
.header-ads {
position: relative;
top: 30px;
float: right;
}headher.php
<div class="header-ads">
<a href="https://cex.io/r/0/cwmills/0/" title="Bitcoin Mining and Trading" target="_blank"><img src="http://cex.io/img/b/728x90.jpg" width="628" height="90" border="0" alt="CEX.IO"></a>
</div><!--/ .header-ads -->How do I make this look better on an android or iphone/ipad device?
