My coding that I have for my room boxes is this:

<style type= "text/css">
.gram { background-color: #003952; border-color: #0075B2; border-width: 1px; width: 125px; height: 200px; color: #ff0000 !important; }
.gram a:link { color: #ffffff; }
</style>

You can use a background in the room boxes but would recommend against it with your background in your homesite Livia. A plain colour would suit it best. I love your background BTW.

You can also change the journal boxes in much the same way. My coding for the journal boxes:

<style type="text/css">
td * div * div { background-color: #003952; border-color: #0075B2; border-width: 1px; font-family: arial;}
</style>

With this coding all you need to do is a copy and paste. Don't forget to change the hex code colours. *G*

Hope this helps. :-D
