  1. Power Websites CMS and CSS VCE IT Theory Slideshows By Mark Kelly McKinnon Secondary College Vceit.com

  2. Contents • Static websites • CMS – Content Management System • CSS – Cascading Style Sheets

  3. Static Websites • Each page is produced by hand, using GUI web editor (e.g. Dreamweaver) or raw HTML code • Pages never change without being edited • Can be dull and unresponsive to current conditions • Imagine a static eBay site where the finishing time of all auctions had to be entered by hand every second.

  4. Dynamic Websites • Constantly changing – e.g. eBay • Can respond to events and the profile of the user • Can be achieved to a degree with Javascript (e.g. a countdown timer on a static page)

  5. Content Management Systems • CMS • Examples – Wordpress, Joomla, Drupal • Database-driven software that creates pages when needed and tailor-makes them for the time, the circumstances, the user

  6. CMS • The CMS fetches content (e.g. text, data, pictures) from the database and creates a webpage with pre-defined formatting chosen by the webmaster. • The same pages might look different for each person viewing it (e.g. their ‘My eBay’ pages, or their Facebook pages.)

  7. Pros and cons

  8. Webmaster creates content (e.g. body text)

  9. Media (pix, videos etc) are stored in the database

  10. The CMS combines content, media, formatting to create web pages which are sent to the visitor’s browser

  11. Cascading Style Sheets • CSS • Instead of repetitively formatting lots of types of text in the same way, define the formatting in a CSS file and just mark text with the style it needs

  12. CSS • To change the look of main headings, change the definition of HEADING1 once in the CSS file. • Don’t have to find and change every piece of HEADING1 text across the site • Far quicker, easier • Creates consistently formatted sites

  13. CSS • E.g. CSS file contains “Heading 1 = Bold, TNR, size 20” • In a webpage, some text is tagged as being “Heading 1” style.
