I am a person who does not know javascript. For now. I made a small homepage design with PHP. There is a textbox and it searches Google. However, I couldn't find how to add autocomplete to it.

My homepage.php's HTML result:

<form action="https://www.google.com/search" method="GET" role="search"><center>
Search Web:<br>
<input id="meow" class="FormControl" maxlength="2048" name="q" type="text" autocomplete="off" autofocus="""><br>
<button type="submit" class="Button Button--primary">Google Search</button>
<br><br>This page will direct you to the Google search engine.

I saw on the internet there is a JSON file that does this but I have no idea how to use it.
