Angular ResponsiveBox - Arrange Layout Elements

All layout elements are arranged against a layout grid. For example, suppose that you have the following layout grid.

jQuery
JavaScript
CSS
$(function() {
    $("#responsiveBoxContainer").dxResponsiveBox({
        rows: [
            { ratio: 1 },  // Header
            { ratio: 2 },  // Content
            { ratio: 0.7 } // Footer
        ],
        cols: [
            { ratio: 0.5, screen: "md lg" }, // Left-side bar
            { ratio: 2 },                    // Content
            { ratio: 0.5, screen: "md lg" }  // Right-side bar
        ]
    });
});
html, body { height: 100%; }

<dx-responsive-box id="responsiveBox">
    <dxi-row [ratio]="1"></dxi-row>     <!-- Header -->
    <dxi-row [ratio]="2"></dxi-row>     <!-- Content -->
    <dxi-row [ratio]="0.7"></dxi-row>   <!-- Footer -->
    <dxi-col [ratio]="0.5" screen="md lg"></dxi-col>     <!-- Left-side bar -->
    <dxi-col [ratio]="2"></dxi-col>                      <!-- Content -->
    <dxi-col [ratio]="0.5" screen="md lg"></dxi-col>     <!-- Right-side bar -->

        <DxRow :ratio="0.7"/>   <!-- Footer -->

        DxResponsiveBox,
        DxCol,
        DxRow
    }
};

CSS
import React from 'react';
import 'devextreme/dist/css/dx.light.css';

import ResponsiveBox, { Row, Col } from 'devextreme-react/responsive-box';

class App extends React.Component {
    render() {
        return (
            <ResponsiveBox>
                <Row ratio={1}/>     {/* Header */}
                <Row ratio={2}/>     {/* Content */}
                <Row ratio={0.7}/>   {/* Footer */}
                <Col ratio={0.5} screen="md lg"/>   {/* Left-side bar */}
                <Col ratio={2}/>                    {/* Content */}
                <Col ratio={0.5} screen="md lg"/>   {/* Right-side bar */}
            </ResponsiveBox>
        );
    }
}

export default App;
html, body { height: 100%; }

Every layout element has the location property that allows you to relocate the element within the layout grid or hide it on screens of a specific size. For example, in the following code, the "Left-Side Bar" and "Right-Side Bar" elements are present only on medium and large screens. All the other elements have individual settings for screens of each size.

If on some screens, all elements should be arranged in a single column, assign the size qualifiers of these screens to the singleColumnScreen property. In this case, the layout grid will be ignored in favor of the single-column layout, and all layout elements will have equal heights.
