In HTML, a form element represents an interactive section containing controls for submitting information. It's through an HTML form that a website owner would typically collect information and store it in the server or use it for other purposes.
You can use an HTML form on your website to collect user information, including their biodata, personal preferences, the purpose for visiting your website, and more.
We are learning the form HTML elements so that we are able to later learn about how to style them well using CSS. It is not recommended that you create your WordPress forms directly in HTML.
