Answer 1

Create a container div first. add the close button on it. Then create a child div inside it and attach the legend to the child div.

<div id="containerDiv">
 <button type="button">X</button>
 <div id="legendDiv"><div>
</div>
var legend = new Legend({ 
 map: map, 
 layerInfos: [{ 
 layer: layer1, 
 title: "Layer1 Legend" 
 }] 
 }, "legendDiv");
