choose the div containers used for the slippy map

<body>

<div id="map"></div>
<div id="elevation-div"></div>
...
</body>

create your first simple “leaflet-elevation” slippy map

<script>
  var opts = {
    map: {
      center: [41.4583, 12.7059],
      zoom: 5,
      markerZoomAnimation: false,
      zoomControl: false,
    },
    zoomControl: {
      position: 'topleft',
    },
    otmLayer: {
      url: 'https://{s}.tile.opentopomap.org/{z}/{x}/{y}.png',
      options: {
        attribution: 'Map data: &copy; <a href="http://www.openstreetmap.org/copyright">OpenStreetMap</a>, <a href="http://viewfinderpanoramas.org">SRTM</a> | Map style: &copy; <a href="https://opentopomap.org">OpenTopoMap</a> (<a href="https://creativecommons.org/licenses/by-sa/3.0/">CC-BY-SA</a>)',
        /*subdomains:"1234"*/
      },
    },
    elevationControl: {
      url: "https://raruto.github.io/examples/leaflet-elevation/via-emilia.gpx",
      options: {
        position: "topleft",
        theme: "magenta-theme", //default: lime-theme
        useHeightIndicator: true, //if false a marker is drawn at map position
        interpolation: d3.curveLinear, //see https://github.com/d3/d3/wiki/
        collapsed: false, //collapsed mode, show chart on click or mouseover
        elevationDiv: "#elevation-div",
        detachedView: true,
        responsiveView: true,
      },
    },
    layersControl: {
      options: {
        collapsed: false,
      },
    },
  };

  var map = new L.Map('map', opts.map);

  var baseLayers = {};
  baseLayers.OTM = new L.TileLayer(opts.otmLayer.url, opts.otmLayer.options);

  var controlZoom = new L.Control.Zoom(opts.zoomControl);
  var controlElevation = L.control.elevation(opts.elevationControl.options);
  var controlLayer = L.control.layers(baseLayers, null, opts.layersControl.options);

  controlZoom.addTo(map);
  controlLayer.addTo(map);
  controlElevation.loadGPX(map, opts.elevationControl.url);

  map.addLayer(baseLayers.OTM);
