I've got the best result with the following  thanks to jQuery
$(document).ready(function() {
    // Handler for .ready() called.

    var alt = $(".wrapper").height();
    $(".left-side").height(alt);
    $(".sidebar").height(alt - 153);
    var altHeader = $("header.header").height();
    $(".sidebar-menu").height(alt - 153);

});
