За този урок ще са ни нужни 2 файла : calculator.css И calculator.php .
Да започваме:

първо с calculator.css :

Код: 
 }
a:link
{
	text-decoration: none;
	color: #000000;font-size:10pt 
}
a:visited
{
	text-decoration: none;
	color: #000000;font-size:10pt 
} 
a:active 
{
	text-decoration: none;
	color: #000000;font-size:10pt
}
a:hover {
	text-decoration: underline;
	color: #000000;font-size:10pt
} 
body
{
	font-size: 10pt; font-family: Verdana; vertical-align: baseline;
	background-color: #FFFFFF;
	color: #000000;
	SCROLLBAR-BASE-COLOR: #FFFFFF;
	SCROLLBAR-ARROW-COLOR: #000000;
}
table
{
	font-size: 10pt; font-family: Verdana; vertical-align: baseline;
	table-border-color-light: #000000;
	table-border-color-dark: #000000; 
}
cell
{
	font-size: 10pt; font-family: Verdana; vertical-align: baseline;
	cell-border-color-light: #000000;
	cell-border-color-dark: #000000; 
}
h1, h2, h3, h4, h5, h6
{
	font-family: Verdana, Helvetica; color:#000000
}
h1
{
	font-size:18pt; font-weight:bold
}
h2
{
	font-size:16pt; font-weight:bold
}
h3
{
	font-size:14pt; font-weight:bold 
}
h4
{
	font-size:12pt; font-weight:bold
}
h5
{
	font-size:10pt; font-weight:bold
}
h6
{
	font-size:8pt; font-weight:bold
}
SELECT       	
{
	font-family:Verdana;font-size:10pt;background:#FFFFFF;color:#000000;
}
INPUT
{
    font-family:Verdana;font-size:10pt;background:#FFFFFF;color:#000000;
}
TEXTAREA     	
{
	font-family:Verdana;font-size:10pt;background:#FFFFFF;color:#000000;
}
hr				{color: #000000; background-color: #FFFFFF; height: 1px; width: 50%;}
Готови сме с визията на каалкулатора.
Сега да минем към него самия calculator.php :
Код: 
<?php
function square( $number )
{
$newNumber = $number * $number;
return
$newNumber;
}
function cube( $number )
{
$newNumber = $number * $number * $number;
return
$newNumber;
}
?>
