Creating a large textbox to get a paragraph input

You need to use textarea

<textarea name="paragraph_text" cols="50" rows="10"></textarea>

Required Attributes

• rows is used to define the number of viewable rows.
• cols is used to specify the number of viewable columns.

Or you can just right-click on the area of the website you're showing us and select "inspect". (You can do it even if you type on the textbox "Your Answer" in stackoverflow) This way you will also know all css and javascript settings that give to such element the specific style you're looking at. Works in all major browsers. :P

right click -> inspect
