Quick solution to add styled contents.

[immmdreza]

Added style: ContentStyle to the canvas's block to store style for each block.

Methods draw_styled_char and draw_styled_line are now available in Canvas.

Here is how you can add style to a char (or line).

sc.draw_styled_char(self, 'E', ContentStyle::new().red().into());

self.canvas
    .draw_styled_line(2, format!(" Score: {} ", self.player.score), ContentStyle::new().black().on_white().into())
