## Description
< section id = 'description' >
In our HTML document, we have a form element with an `id` attribute: `<form id="calorie-form">`
To reference and access this particular form in JavaScript, we can use the getElementById() method on the document and provide the ID.
The code `document.getElementById('my-form')` gets a reference to an HTML element with an `id` of `my-form` . Get a reference to the HTML element with the `id` of `calorie-form` .
