While polishing my site I noticed there was some unwanted space between 2 elements, so I decided to remove it. But looking at the source, I found this:
Please check it by yourself, there's no trace of this server-side. Live page here: http://www.playersonline.com.ar/guias
Any help would be appreciated.
Not sure where the mysterious whitespace is coming from, but modifying your #k2Container
CSS will solve the problem for you:
#k2Container {
padding:0;
position: relative;
top: -20px; /* adjust as needed */
}
