HTML 5 <textarea> Tag
The HTML <textarea> tag is used within a form to declare a textarea element - a control that allows the user to input text over multiple rows.
In HTML 5, the maxlength attribute enables you to specify a maximum length for your <textarea> element. This attribute was not supported in previous versions of HTML.
Also see the <form> tag.

Attributes
HTML tags can contain one or more attributes. Attributes are added to a tag to provide the browser with more information about how the tag should appear or behave. Attributes consist of a name and a value separated by an equals (=) sign, with the value surrounded by double quotes. Here's an example, style="color:black;".
There are 3 kinds of attributes that you can add to your HTML tags: Element-specific, global, and event handler content attributes.
The attributes that you can add to this tag are listed below.
