Position "fixed" looks like "absolute"

Hi!

First of all – do not fix the whole sidebar! Remove sidebar-single from custom id list!
Second. Set higher Refresh Interval. Try values from 1000. 100 is a causing high cpu usage!
Third. Make change in style.css:

#sidebar-single {
float: left;
width: 300px;
text-align: left;
padding-top: 143px;
/* position: relative; */
}

Disable position: relative property!

Ok! The last change in style.css:

kung.tk/media="all"
#page {
position: relative;
width: 100%;
padding-bottom: 2rem;
-webkit-transition: -webkit-transform 500ms ease;
-moz-transition: -moz-transform 500ms ease;
-o-transition: -o-transform 500ms ease;
transition: transform 500ms ease;
/* -webkit-transform: translate(0, 0);
-moz-transform: translate(0, 0);
-o-transform: translate(0, 0);
transform: translate(0, 0); */
}

Disable -webkit-transform and other transform properties!
