which file(s) determines layout?
Is there a file that is editable so a user can modify the look of their gallery. In other words, say for example if they wanted to change the table layout so it doesn't stretch 100% of the screen and wanted to update the main page background after decreasing that table width. How easily is that achieved and which file(s) would they edit?
Will this edit have to be made in multiple files or just a single file if using the default theme?
