Note, that the DHTMLX library provides a set of own CSS classes that you can also apply to change the appearance of a Layout cell.

const layout = new dhx.Layout("layout_container", {
    css: "dhx_layout-cell--bordered",
    rows: [
        {
            id: "toolbar",
            html: "Header",
            css: "dhx_layout-cell--border_bottom layout-header",
            gravity: false,
            height: "60px"
        }
    ]
});
