Question

I have 2 horizontal divs next to each. I all trying to get the div on the right to shrink down as the window is made made smaller but it drops to the next line. Also I want the div on the right to reach the outer border of its container div.

The only success i have is if a put a percentage width on the right div but then it does touch the container border.

Hey now remove float left of this class

#rsfeed .rsfeedinfo

and add white-space nowrap in your id #rsfeed
As like this

    #rsfeed .rsfeedinfo {
    float:left;  // remove this line
    }

#rsfeed {
white-space:nowrap; //add this line
}
