HTML - cols Attribute
The HTML cols attribute is used to set or specify the visible width of a text area element. If it is used within a textarea element.
If we haven't specified any value for the cols attribute, it will automatically consider the default value which is 20. Instead of the cols attribute, we can use the CSS width property to set the visible width of this element.
The cols attribute works with both <textarea> and <frameset> tags, Since the <frameset> tag is not supported in HTML5, we will use it with <textarea> only.

<textarea cols = "value"></textarea>
