Column-span

The column-span style specifies how many columns a widget will span in a grid layout.

Note

This style only affects widgets that are direct children of a widget with layout: grid.

Syntax

column-span: <integer>;

The style column-span accepts a single non-negative <integer> that quantifies how many columns the given widget spans.

Example

The example below shows a 4 by 4 grid where many placeholders span over several columns.

MyApp #p1 #p2#p3 #p4#p5 #p6#p7

from textual.app import App
from textual.containers import Grid
from textual.widgets import Placeholder


class MyApp(App):
    def compose(self):
        yield Grid(
            Placeholder(id="p1"),
            Placeholder(id="p2"),
            Placeholder(id="p3"),
            Placeholder(id="p4"),
            Placeholder(id="p5"),
            Placeholder(id="p6"),
            Placeholder(id="p7"),
        )


app = MyApp(css_path="column_span.css")
#p1 {
    column-span: 4;
}
#p2 {
    column-span: 3;
}
#p3 {
    column-span: 1;  /* Didn't need to be set explicitly. */
}
