+
+            <ul>
+                <li>
+                    Chat Settings: by clicking on the blue menu button on the top-right corner of the page, the
+                    Display tab has a "Video size" dropdown with some options to change the size of all videos
+                    open on your screen.
+                </li>
+                <li>
+                    On wide screens (such as an iPad in landscape orientation): when you have videos open, look
+                    for the <i class="fa fa-magnifying-glass-plus"></i> <i class="fa fa-magnifying-glass-minus"></i>
+                    buttons in the header just above the video dock. Clicking on these buttons will scale the docked
+                    videos larger or smaller (in similar increments as the Chat Settings dropdown).

+            </ul>
+
+            <p>
+                If you are on a device with a mouse cursor, such as a desktop or a laptop with a touchpad, there
+                are a couple of ways to resize individual videos how you see fit:
+            </p>
+
+            <ul>
+                <li>
+                    When videos are docked in the top of the page, hover your mouse over the bottom-right corner
+                    of a video. It should show a 'resize' cursor, and you can click and drag from the bottom-right
+                    corner to resize the video.
+                </li>
+                <li>
+                    Videos can also be "popped out" of the dock at the top of the page. The pop-out button appears
+                    on top of videos, next to the mute audio button. When popped out, you can drag videos anywhere
+                    on the page and you can resize them by dragging from any edge except the top.
+                </li>
+            </ul>
+
+            <p>
+                And finally: you can put a video "full screen" too. In the control buttons at the bottom of each
+                video (beginning with the mute audio button), the one on the right will toggle the video into a
+                full screen view.
