 Copy the following code, and paste it into a <div> element in your site's <body> section, where you want both of the search box and the search results to render.

<script async src="https://cse.google.com/cse.js?cx=909d3264e96435878"></script>
<div class="gcse-search"></div>

 Note: For maximum compatibility your pages must specify an HTML5 doctype and a viewport.
<!DOCTYPE html>
<meta name="viewport" content="width=device-width, initial-scale=1">
