If the picture is a "verticular" image. Because it is "tiling", it
gives an illusion of a fading background.
Background - table
Similarly to putting an image on the background,
you can put one inside a cell.
<TABLE border="1" width="600" height="400">
<TR>
<TD width="300" background="blue.gif"></TD>
<TD width="300" background="brown.gif"></TD>
</TR>
</TABLE>

Text Fields
Input fields are going to be the meat of your form's sandwich.
The <input> has a few attributes that you should be aware of.
type - Determines what kind of input field it will be. Possible
choices are text, submit, and password.
name - Assigns a name to the given field so that you may
reference it later.
size - Sets the horizontal width of the field. The unit of
measurement is in blank spaces.
maxlength - Dictates the maximum number of characters that
can be entered.

one option. If name is different, you allow multiple option).

Rows and columns need to be specified as attributes to
the <textarea> tag. Rows are roughly 12pixels high, the
same as in word programs and the value of the columns
reflects how many characters wide the text area will be.
i.e. The example shows a text area 5 rows tall and
20 characters wide.
