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.
