When attempting to use flags as a way to switch between languages, I encountered an issue in Firefox where a small box appears between the images on the Hebrew site. In Chrome, everything works fine.
I implemented the following code:
<div class="flags">
<a href="http://www.drmosko.com/"><img src="./images/english-flag.jpg"></a>
<a href="http://www.drmosko.com/he/"><img src="./images/hebrew-flag.jpg"></a>
</div>
Link for correct display:
