WEB DEVELOpmentImmersiVEHTML & Web Fundamentals Topics
  • How the Web Works
  • The Development Process
  • Separation of Concerns
  • Work Flow Habits
  • Getting to know HTML elements
  • Validation
  • WEB DEVELOPMENT IMMERSIVE How the web works
  • Request/Response
  • Rendering in the browser
  • Local / Remote
  • Frontend / Backend Development
  • WEB DEVELOPMENT IMMERSIVE Request / response WEB DEVELOPMENT IMMERSIVE Conversation: passing html, css, & js WEB DEVELOPMENT IMMERSIVE Rendering in the browser
  • Each browser has its own rendering engine to interpret and display the markup
  • WEB DEVELOPMENT IMMERSIVE Rendering in the browser
  • Top to bottom, left to right
  • WEB DEVELOPMENT IMMERSIVE Local / remote WEB DEVELOPMENT IMMERSIVE FTP (File transfer protocol) Things you will need to connect:
  • Ftp Address
  • User login
  • Password Should be provided by your host company or server admin.
  • INTRODUCTION TO WEB DEVELOPMENT DEVelopment Front end (client-side)
  • HTML
  • CSS
  • Javascript
  • Back end(server-side)
  • Ruby
  • PHP
  • Python
  • PERL
  • C++
  • Node.js
  • WEB DEVELOPMENT IMMERSIVE DEVelopment PROCESS
  • Work Cycle
  • Planning
  • Stages
  • WEB DEVELOPMENT IMMERSIVE A Typical Web Development Cycle User-Experience (UX) Information Architecture (IA) Design Development WEB DEVELOPMENT IMMERSIVE 1 UX
  • Who is our target audience?
  • How do we know if the user is hitting their goals?
  • What are the most important features of this site?
  • WEB DEVELOPMENT IMMERSIVE 1 UX User Needs Business Needs Best Practices Ideal Experience WEB DEVELOPMENT IMMERSIVE 2 IA A model or blueprint for the site Resulting in deliverables such:
  • wireframes
  • flow diagrams
  • sitemap
  • WEB DEVELOPMENT IMMERSIVE 2 IA : The Blueprint Sitemaps & Flow Diagrams Establish flow and order Wireframes & Content Define the user interaction and ease the handoff process to the creative team WEB DEVELOPMENT IMMERSIVE Small Site WEB DEVELOPMENT IMMERSIVE Large Site WEB DEVELOPMENT IMMERSIVE Hand drawn WEB DEVELOPMENT IMMERSIVE Brainstorming WEB DEVELOPMENT IMMERSIVE Functional WEB DEVELOPMENT IMMERSIVE Minimal WEB DEVELOPMENT IMMERSIVE iPhone WEB DEVELOPMENT IMMERSIVE 3 Design Wireframes become design comps WEB DEVELOPMENT IMMERSIVE 3 Design Each wireframe template, becomes a comp template Homepage Blog 2 column top 1 column bottom 2 column top 2 column bottom WEB DEVELOPMENT IMMERSIVE 4 FRONT END DEVELOPMENT Comps become graphics & real text general-assembly-logo.png Real Text: General Assembly offers classes, and events at the intersection of technology, design, and entrepreneurship. Together with our members, thought leaders, and seasoned practitioners, we offer a robust curriculum focused on WEB DEVELOPMENT IMMERSIVE 5 back END DEVELOPMENT Interacts with database and executes commands acting as a controller that mediates between the database model and the front end users view. If we go to www.zappos.com and search for a pair of shoes, the visual display of the images, the price and the green button "Add To Cart" is all part of the front-end. Now, when I click "Add To Cart" and this an item is moved to my shopping cart in the backend there is some logic written that says something like: "The user just clicked a button, so add this item temporarily to the database and remember this item for the user." The backend takes care of the actions and the directions of how and where to store data. WEB DEVELOPMENT IMMERSIVE Separation of concerns
  • HTML = structure (content)
  • CSS = style
  • Javascript = behavior
  • WEB DEVELOPMENT IMMERSIVE Site organization WEB DEVELOPMENT IMMERSIVE HTML basics
  • Syntax
  • Document Structure
  • Content Tags
  • Element Display

  • File Types
  • Resolution & Color Mode
  • Compression
  • Attributes
  • INTRODUCTION TO WEB DEVELOPMENT Common File types
  • GIF (Graphics Interchange Format)
  • JPG (JPEG) (Joint Photographic Experts Group)
  • PNG (Portable Network Graphic)
  • BMP (Bitmap)
  • SVG (Scalable Vector Graphic)
  • INTRODUCTION TO WEB DEVELOPMENT Lossyvs lossless
  • Lossless data compression makes use of data compression algorithms that allows the exact original data to be reconstructed from the compressed data
  • Lossy data compression does not allow the exact original data to be reconstructed from the compressed data.
  • INTRODUCTION TO WEB DEVELOPMENT GIF (graphic interchange format)
  • Lossless compression that simplifies color pallette to reduce file size.
  • Best for sharp edged graphics with smaller range of colors. (ex: text, simple logos, and icons)
  • Not good for complex gradients or millions of colors (ex: photos)
  • INTRODUCTION TO WEB DEVELOPMENT JPG (joint photographic experts group)
  • Lossy compression that reduces file size by loss in image fidelity.
  • Best for photographs and paintings of realistic scenes with smooth variations of tone and many colors.
  • Not as sharp at depicting text, and icons as GIF or PNG.
  • INTRODUCTION TO WEB DEVELOPMENT PNG-8 (portable network graphic 8 bit)
  • Lossless data compression that was meant to replace GIF.
  • PNG-8 works well with text, icons, and logos with sharp edges and simplified color palettes.
  • Creates much larger file sizes on photos than JPGs.
  • INTRODUCTION TO WEB DEVELOPMENT PNG-24 (portable network graphic 24 bit)
  • A higher 24 bit version of PNG.
  • Excellent results for images with transparency, which makes it work well for UI buttons. Good at both sharp edged simplified palettes and large color range gradients.
  • Will create a larger file size than JPG for photos however.
  • INTRODUCTION TO WEB DEVELOPMENT Bmp (bitmap)
  • Left over from the days of oldver vesions os OS2 and Windows, Bitmaps for web use dithering, pattern or noise inclusion to reduce file size.
  • Good for making retro web 1.0 graphics.
  • Not ideal for maintaining clarity in web images at reasonable file sizes.
  • INTRODUCTION TO WEB DEVELOPMENT svg (scalable vector graphic)
  • Lossless format that can optionally be defined as vector points instead of pixels allowing scaling.
  • Good for scalable graphics.
  • Has limited support in older versions of Internet Explorer 8 and below.
  • INTRODUCTION TO WEB DEVELOPMENT CHOOSING image RESOLUTION There are only 72 pixels per inch on your screen.
  • Web = 71 dpi (ppi)
  • Print Newspaper = 100 dpi (ppi)
  • Print Magazine = 300 dpi (ppi)
  • [NAME OF PROGRAM] CERTIFICATE PROGRAM CHOOSING color modes Our screens display colors in RGB.
  • Web = RGB (Red, Green, Blue)
  • Print = CMYK (Cyan, Magenta, Yellow, Black)
  • [NAME OF PROGRAM] CERTIFICATE PROGRAM Image TAg <img src=”myimage.jpg" alt="Alternate Text" title=”Display Title” width=”800" height=”600" /> [NAME OF PROGRAM] CERTIFICATE PROGRAM LINKS
  • Attributes (href, target)
  • Relative vs Absolute
  • Types (url, named anchor, mailto)
  • INTRODUCTION TO WEB DEVELOPMENT LINK TagS <a href="http://www.example.com/">This is a Link</a> <a href="http://www.example.com/"> <img src="URL" alt="Alternate Text"> </a> <a href="mailto:webmaster@example.com">Send e-mail</a> A named anchor: <p id="tips">Useful Tips Section</p><a href="#tips">Jump to the Useful Tips Section</a> INTRODUCTION TO WEB DEVELOPMENT Relative vs absolute <a href="http://www.example.com/">This is an absolute url Link</a> VS <a href=”about.html">This is a relative url Link</a> Relative urls, link to content inside the same site and provides a file path relative to the relationship between the two files. Whether internal to the site or on an external domain, absolute urls provide the full http url in the file path. INTRODUCTION TO WEB DEVELOPMENT Element display WEB DEVELOPMENT IMMERSIVE Meta data
