"role": "heading", "text": "News", "format": "markdown", "textStyle": { "textAlignment": "center", "backgroundColor": "#006FBA", "textColor": "#FFFFFF", "fontSize": 14, "lineHeight": 16, "fontWeight": "bold", "fontScaling": false }, "style": { "backgroundColor": "#006FBA" }, "layout": { "padding":5, "ignoreDocumentMargin": false, "margin": { "bottom": 15, "left":30, "right":30 } } }, { "role": "heading", "text": "News", "format": "markdown", "textStyle": { "textAlignment": "center", "backgroundColor": "#006FBA", "textColor": "#FFFFFF", "fontSize": 14, "lineHeight": 16, "fontWeight": "bold", "fontScaling": false }, "layout": { "padding":5, "ignoreDocumentMargin": false, "margin": { "bottom": 15, "left":30, "right":30 } } }, { "role": "container", "components": [ { "role": "heading", "text": "News", "textStyle": { "textAlignment": "center", "backgroundColor": "#006FBA", "textAbove": "1", "textColor": "#FFFFFF", "fontSize": 14, "lineHeight": 16, "fontWeight": "bold", "fontScaling": false }, "style": { "backgroundColor": "#006FBA" }, "layout": { "padding":5 } } ] },
