Tumbling Dice Program - PHP/HTML/CSS

Question: Roll two dice 1,000 times. Create a program that simulates the rolling of dice 500 times. Record the result of each roll that equals 7 (e.g. 1+6=7, 2+5=7, 3+4=7) and display totals for the total number of rolls that equal 7.

This needs to have an html page, php page, and css page

The result, after executing the program, should look similar to:

"The number of sevens (7) that occured in 500 dice rolls was: 165"
