Tips for beginners (and not only): some tips to save time and efforts in developing and following the exercices of this guide: >> Don't make major modifications without backup of the previous file and without previewing it in browser.
work always on a copy of the files: it's a good use professional developpers have...this means when you open theme.html in next chapter to modify it, create a copy of the original site and call it example: themebak1.html. Edit then theme.html. In chapter f. when you reopen theme.html for further editing, copy your last theme.html and rename it themebak2.html and work on theme.html.... this way you will have a lot of back up files, but you can at the end of the guide return back at a certain point of design and begin a new way or restart coding in different way... for example to insert header images, etc. You will certainly gain in time and efforts also if something goes wrong with the modifications you last made.
Test every change you make: only way to test the HTML code is to view it with the browser: I work like this: have the HTML open in the web editor (Block Note, DreamWeaver, OpenOffice.org or what else you prefer), make the changes, save, leave the editor open, open Browser, point to the local site ( http://127.0.0.1/mdpro/index.php?theme=ATTest or http://localhost/mdpro/index.php?theme=ATTest ), make arefresh and see the modifications on line. Reopen editor, make changes, view them on browser just refreshing page, and so on. Preview in browser every little change in code ! It will be easier to track eventual errors....
