Thank you very much - your feedback is valuable!

If I read your pictures correctly, in portrait mode there is a blue border around the header section, meaning that it has loaded my custom css for smaller screens. But judging by the screenshot, it is hard to say if there are other problems but possibly the text being bit too small to read conveniently?

In the screen picture of horizontal landscape mode I don't see the blue border, so probably the screen width was big enough not to trigger custom css.

Well, for the next few days I'll be rather busy with other things, but I'll return to this as soon as possible! (Trying a few small things today, though)

EDIT: I'm not sure if it works correctly, but I tried to add so that if user screen height is less than 400px, the place description box max height is restricted to 120px, giving it scrollbars if the content text is longer. Also, for debugging purposes the background color is less bright green. Hope it works!
