[HTML] <!DOCTYPE HTML>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="initial-scale=1, maximum-scale=1,user-scalable=no">
<title>Home Extent</title>
<link rel="stylesheet" type="text/css" href="http://js.arcgis.com/3.9/js/esri/css/esri.css">
<link rel="stylesheet" href="http://js.arcgis.com/3.9/js/dojo/dijit/themes/claro/claro.css">
<style>
    html, body, #map {
      padding:0;
      margin:0;
      height:100%;
    }
    #HomeButton {
      position: absolute;
      top: 95px;
      left: 20px;
      z-index: 50;
    }
</style>
<script src="//js.arcgis.com/3.9/"></script>
<script>

     require([

      "esri/dijit/HomeButton",
      "dojo/domReady!"
    ], function(

       HomeButton
    ) {


      var home = new HomeButton({
        map: map
      }, "HomeButton");
      home.startup();

    });




      require([
        "esri/map", "esri/dijit/HomeButton", "esri/dijit/BasemapGallery", "esri/arcgis/utils",
        "dojo/parser",

        "dijit/layout/BorderContainer", "dijit/layout/ContentPane", "dijit/TitlePane",
        "dojo/domReady!"
      ], function(
        Map, HomeButton, BasemapGallery, arcgisUtils,
        parser
      ) {

        parser.parse();
      var map = new Map("map", {
          basemap: "topo",
          center: [-98.185272, 26.282376],
          zoom: 9
        });
        var basemapGallery = new BasemapGallery({
          showArcGISBasemaps: true,
          map: map
        }, "basemapGallery");
        basemapGallery.startup();

        basemapGallery.on("error", function(msg) {
          console.log("basemap gallery error: ", msg);
        });
      });




    </script>

Hi and welcome to the forums!

Here is a sample from our documentation showing exactly what you want.
https://developers.arcgis.com/javascript/jssamples/widget_home.html

Please take the time to read the documentation on both our API and the DOJO library.
