  5. <What is the client side?/><What is scripting?/>

  6. Client side scripting • Client-side scripting generally refers to the class of computer programs on the web that are executed client-side, by the user's web browser, instead of server-side (on the web server).  • This type of computer programming is an important part of the Dynamic HTML (DHTML) concept, enabling web pages to be scripted; that is, to have different and changing content depending on user input, environmental conditions (such as the time of day), or other variables. • Javascript

  7. Recap of Day 1 (4) Client/Server architecture:

  8. Client side scripting • Web systems use a combination of client side scripting (HTML/Javascript/XML) and server side programming (php/ASP.Net/Java)

  9. .Net framework – the CLR

  10. <What is HTML?/><What is CSS?/><What is Javascript?/>

  11. What is HTML? • HTML is a language for describing web pages. • HTML stands for Hyper Text Markup Language • HTML is not a programming language, it is a markup language • A markup language is a set of markup tags • HTML uses markup tags to describe web pages • More about HTML soon (first 2 weeks of this course)

  12. What is CSS? • CSS stands for Cascading Style Sheets • Styles define how to display HTML elements • Styles were added to HTML 4.0 to solve a problem • External Style Sheets can save a lot of work • External Style Sheets are stored in CSS files • More about CSS ….

  13. What is Javascript? • JavaScript was designed to add interactivity to HTML pages (movement/changes/actions) • JavaScript is a scripting language • A scripting language is a lightweight programming language • JavaScript is usually embedded directly into HTML pages • JavaScript is an interpreted language (?) • Everyone can use JavaScript without purchasing a license – its free!
