How to debug layout?

[spaghetti-software-inc]

Hello,

How can I debug a textual app layout at run-time? In HTML/CSS/JS, we can use borders around elements to visually debug. It would also be useful to be able to output the layout state (width/height/position) of each widget in the app at run-time; I'm not sure how to do this.

Thanks

You can put borders around things in Textual as well.

You can do self.log(self.css_tree) from any widget to output the DOM to the textual console.
