An example of view Google Maps in HTML page from scratch complete with setup Google Maps Javascript API

In this HTML 5 tutorial, we will show you how to view Google Maps in the HTML page in just a few lines of HTML tags, CSS, and Javascript codes. We will start this tutorial with the setup of Google Maps API in the Google Developer Console. After that, we will display or view Google Maps in the HTML page using the created Google API Key. Configuration and layout will be done using a little Javascript and CSS codes.

Setup Google Maps API Key

To view Google Maps in the HTML page using Javascript API we need a Google Maps API key. The Google Maps JavaScript API lets you customize maps with your own content and imagery for display on web pages and mobile devices. The Maps JavaScript API features four basic map types (roadmap, satellite, hybrid, and terrain) which you can modify using layers and styles, controls and events, and various services and libraries.

Next, open your browser the go to the Google Developer Console. You will be taken to this Google Developer Console page.

View Google Maps in HTML Page

Now, we will create an HTML page from scratch starting by creating a new HTML file in your project folder. You can create the HTML file using your text editor, IDE, or terminal/command line. Next, open and edit that HTML file then adds these HTML tags that just contain a div for viewing Google Maps.

<!DOCTYPE html>
<html>
  <head>
    <title>HTML Google Maps</title>
    <meta name="viewport" content="initial-scale=1.0">
    <meta charset="utf-8">
  </head>
  <body>
    <div id="map"></div>
  </body>
</html>

As you can see, we declare an HTML 5 page by defining HTML using this tag <!DOCTYPE html>. Next, include the Google Maps Javascript API before the closing of </body> tag.

<script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&callback=initMap"
    async defer></script>

In that Google Maps Javascript API calls include a callback to "initMap" function. Add a Javascript code after or before that Google Maps Javascript API calls.

<script>
  var map;
  function initMap() {
    map = new google.maps.Map(document.getElementById('map'), {
      center: {lat: 53.430938, lng: -2.960841},
      zoom: 17
    });
  }
</script>

Just using the HTML page and Javascript function will not display Google maps in the browser. For that, you have determined the size of MAP DIV using CSS. Add the CSS or STYLE codes before the end of the </HEAD> tag.

<style>
    #map {
      height: 100%;
    }
    html, body {
      height: 100%;
      margin: 0;
      padding: 0;
    }
</style>

Now, you can see the Google Maps in the HTML page like this.
