Sidebar dropping to the bottom under 960 pixels wide

My sidebar falls to the bottom when the screen size is less than 960 pixels wide. Is there a way to keep it on the right? Did I mess this up with my child theme customizations?

I believe the fix/problem is in this code. Note that I have commented out a block of code that did not seem correct:

@media screen and (max-width : 960px) {

.onecol .threecol,
.onecol .fourcol {
width:50%;
}

#wrapper {
max-width:760px;
}

#slider .entry-container {
top:32%;
padding: 0;
}

#slider .entry-summary {
display: none;
}

#container {
margin:2.2%;
}

.content-sidebar-wrap,
#content,
.page-template-template-sidebar-content-sidebar-php .content-sidebar-wrap #content,
#sidebar {
width:100%;
}

.onecol .hentry .entry,
.onecol .hentry #comments,
.onecol .hentry #respond {
margin:2.4%;
}

.onecol .twocol .entry,
.onecol .threecol .entry,
.threefourthcol .threecol .entry,
.onecol .fourcol .entry {
margin:4.5%;
}
