Elements are evaluated at "compile time" ie when the page is loaded for the
first time. However, you can  achieve dynamic effects, let me give you an
example:

class Box < Raw::Element
   def render
      %{
      <div style="color: \#{@color}">
        #{content}
      </div>
      }
   end
end

then use it like this:

<?r
colors = [ "#ff0", "#f00", "#00f", #"0ff" ]
?>
<h1>Dynamic boxes</h1>

<Box color="colors[rand(colors.size)]">
   This box is randomly colored ;-)
</Box>
