Web Development Layers

Introduction to Web Development Layers

  • Web Development Layers refers to the different levels at which website creation takes place
  • There are primarily three layers - Structure layer, Presentation layer, and Behaviour layer
  • Different coding languages are used in each layer

Structure Layer

  • The structure layer, also known as the Content Layer, is where the foundation of the website is built
  • HTML (Hyper Text Markup Language) is used to create the basic structure of web pages in this layer
  • Web developers use HTML tags to store headers, footers, content, and links on the page
  • HTML is also used to embed images, video, audio, and other media content
  • This layer primarily focusses on the structure of information, regardless of its presentation or behaviour

Presentation Layer

  • The presentation layer controls the visual layout and appearance of the website
  • Cascading Style Sheets (CSS) is the language used primarily in this layer
  • CSS is used to design the layout, colors, fonts, and other visual elements of the web page
  • CSS can be used to provide multiple styles to different devices or screen sizes (responsive design)
  • While HTML focusses on the structure, CSS allows designers to control how that structure looks

Behaviour Layer

  • The behaviour layer is where the interactive facets of a website are programmed
  • JavaScript is the main language used in the behaviour layer
  • JavaScript allows for web page elements to be manipulated in response to user actions
  • Examples of JavaScript functionality include form validation, interactive maps, and dynamic content updates
  • This layer enables users to interact with the website, improving user experience

How the Layers Interact

  • All three layers are interconnected and work together to create a fully functional website
  • The structure layer gives the website its basic structure, the presentation layer determines how the website looks, and the behaviour layer provides the interactivity
  • Each layer has a specific role, but they cooperate and influence each other
  • Working separately on each layer promotes efficiency and modularity in the web development process

To remember - For a website to function effectively, all three layers must be properly incorporated and balanced.
