+      }
+      if (timers[uniqueId]) {
+        clearTimeout (timers[uniqueId]);

+        sel.each(function () {
+          this.style.height = null;
+        });
+        sel.equalHeight();

+          len = 10;
+        }
+
+        var text = "";
+        var possible = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789";
+
+        for (var i = 0; i < len; i++) {
+          text += possible.charAt(Math.floor(Math.random() * possible.length));
+        }
+
+        return text;
+      })(len)
+    );
+  });
+})('.element');
+```
+
+This keeps the columns responsive and allows the column height to shrink when the window is enlarged.
