A basic form consisting of fields, checkbox, and submit.
A set of fields can appear grouped together.
You may also specify how many fields are in a row by adding the written number as a class along with the "fields" class. This will expand the fields to take up the space provided.
A textarea can be used to allow for extended user input. To specify an approximate text area size use the rows attribute.
You can add other form elements such as Checkboxes/Radio and dropdowns/multi-selects!
