I need to add php / html and css to my database

This is the things i nedd to do for my final school work i dont need anithing super special
DB script -
CRATE DB, CREATE TABLE, INSERT
Project-
Use : <link rel="stylesheet" href="style.css?a=
serves to refresh CSS always to the latest version
CSS in a separate file !!
HTML as HTML - not echo "$name" !!
Nice CSS - can improve/deteriorate
List of 2 tables - one with some FK
Assignment until the next class (31.5.):
Require header, footer, connect
Navigation - table separated from insert - i.e. 4 subpages (2 tables, 2 inserts)
Insert into both tables - after the insert, a prelink to the table (location)
In the insert - basic treatment - list of errors for the user
Insert FK - via and foreach tables
