Create the Layout Grid

All ResponsiveBox elements are arranged against a layout grid defined by the rows and cols arrays. Each object in these arrays configures a single row or column. If you need two sets of equally-sized rows and columns, simply populate these arrays with empty objects.

jQuery
JavaScript
$(function() {
    $("#responsiveBoxContainer").dxResponsiveBox({
        // Creates two rows of equal height
        rows: [
            { }, { }
        ],
        // Creates three columns of equal width
        cols: [
            { }, { }, { }
        ]
    });
});
Angular

<html style="height:100%">
    <body style="height:100%">
        <dx-responsive-box id="responsiveBox">
            <!-- Creates two rows of equal height -->
            <dxi-row></dxi-row>
            <dxi-row></dxi-row>
            <!-- Creates three columns of equal width -->
            <dxi-col></dxi-col>
            <dxi-col></dxi-col>
            <dxi-col></dxi-col>
        </dx-responsive-box>
    </body>
</html>
import { DxResponsiveBoxModule } from 'devextreme-angular';
// ...
export class AppComponent {
    // ...
}
@NgModule({
    imports: [
        // ...
        DxResponsiveBoxModule
    ],
    // ...
})

To set the size of a row/column, use the ratio and baseSize options. The ratio option specifies the size of a row/column in relation to other rows/columns. If you use this option alone, the ResponsiveBox occupies the entire area assigned to it.

jQuery
JavaScript
$(function() {
    $("#responsiveBoxContainer").dxResponsiveBox({
        rows: [
            { ratio: 1 },
            { ratio: 2 },
            { ratio: 0.5 }
        ],
        cols: [
            { ratio: 0.5 },
            { ratio: 2 },
            { ratio: 0.5 }
        ]
    });
});
Angular

<html style="height:100%">
    <body style="height:100%">
        <dx-responsive-box id="responsiveBox">
            <dxi-row [ratio]="1"></dxi-row>
            <dxi-row [ratio]="2"></dxi-row>
            <dxi-row [ratio]="0.5"></dxi-row>
            <dxi-col [ratio]="0.5"></dxi-col>
            <dxi-col [ratio]="2"></dxi-col>
            <dxi-col [ratio]="0.5"></dxi-col>
        </dx-responsive-box>
    </body>
</html>
import { DxResponsiveBoxModule } from 'devextreme-angular';
// ...
export class AppComponent {
    // ...
}
@NgModule({
    imports: [
        // ...
        DxResponsiveBoxModule
    ],
    // ...
})

If you need to set the size of a row/column in pixels, set the ratio to 0 and specify the baseSize option. In this case, if the ResponsiveBox is bigger than all its elements combined, an area is left unoccupied.

jQuery
JavaScript
$(function() {
    $("#responsiveBoxContainer").dxResponsiveBox({
        height: 500,
        width: 500,
        // Rows occupy a total height of 450 pixels, 50 pixels left
        rows: [
            { ratio: 0, baseSize: 150 },
            { ratio: 0, baseSize: 200 },
            { ratio: 0, baseSize: 100 }
        ],
        // Columns occupy a total width of 300 pixels, 200 pixels left
        cols: [
            { ratio: 0, baseSize: 50 },
            { ratio: 0, baseSize: 200 },
            { ratio: 0, baseSize: 50 }
        ]
    });
});

    <body style="height:100%">
        <dx-responsive-box id="responsiveBox"
            [height]="500"
            [width]="500">
            <!-- Rows occupy a total height of 450 pixels, 50 pixels left -->
            <dxi-row [ratio]="0" [baseSize]="150"></dxi-row>

            <dxi-col [ratio]="0" [baseSize]="200"></dxi-col>

To redistribute the unoccupied area between rows/columns, specify the ratio more than 0. The greater the ratio assigned to a row/column, the bigger the area added to this row/column.

jQuery
JavaScript
$(function() {
    $("#responsiveBoxContainer").dxResponsiveBox({
        height: 500,
        width: 500,
        rows: [
            { ratio: 1, baseSize: 150 },
            { ratio: 2, baseSize: 200 },
            { ratio: 1, baseSize: 100 }
        ],
        cols: [
            { ratio: 1, baseSize: 50 },
            { ratio: 2, baseSize: 200 },
            { ratio: 1, baseSize: 50 }
        ]
    });
});

The collections of rows and columns may differ depending on the screen's size qualifier. To specify on which screen types an individual row or column should appear, use the screen option. By default, all rows and columns appear on all screen types.

jQuery
JavaScript
$(function() {
    $("#responsiveBoxContainer").dxResponsiveBox({
        rows: [
            { ratio: 1 },
            { ratio: 2 },
            { ratio: 0.7 }
        ],
        cols: [
            { ratio: 0.5 },
            // The following columns appear on medium and large screens only
            { ratio: 2, screen: "md lg" },
            { ratio: 0.5, screen: "md lg" }
        ]
    });
});
