  1. CISC 474: Advanced Web Technologies HTML5 & CSS3, & Responsive Design

  4. NEW HTML5 Section Elements • Replaces generic “div” • Allows for cleaner layout and “labeled” sections • Nav, Header, Section, Footer • Label Page Content • Article • Address • Most Important Content • Main (only one per doc)

  5. Basics of CSS Box-Model • Width = width + padding-left + padding-right + border-left + border-right • Height = height + padding-top + padding-bottom + border-top + border-bottom Undeclared values (padding and border) are set to zero (css reset) or a browser default (which probably won’t be zero). Undeclared width of block-level elements will be 100%. Floated & Absolute element widths will be only as wide as the content inside them.

  6. Basics of CSS Layout • CSS Reset • Resets all browser-specific defaults • http://meyerweb.com/eric/tools/css/reset/ • Fluid v. Fixed • Percentages vs. Fixed Pixel • All Floating Elements • Floating + Block Elements • All Block Elements

  8. Popular CSS3 Pseudo-classes • Gives control over dynamically created content without adding class or id • :hover, :active, :visited ex.links • :first-child, :last-child ex.Add a top or bottom border • :nth-child(odd), :nth-child(even) ex. Table striping • :enabled, :disabled, :checked

  9. Responsive Design • Responsive design is an approach to web page creation that makes use of flexible layouts, flexible images and cascading style sheet media queries. • The goal of responsive design is to build web pages that detect the visitor's screen size and orientation and change the layout accordingly.

  10. CSS3 Media Queries • Allows content rendering to adapt to conditions such as screen resolution. It became a W3C recommended standard in June 2012 and is a cornerstone technology of Responsive Web Design. • Extra small devices (phones, up to 480px) • Small devices (tablets, 768px and up) • Medium devices (big landscape tablets, laptops, and desktops, 992px and up) • Large devices (large desktops, 1200px and up)

  11. 2 Popular Responsive Design Frameworks • Twitter Bootstrap • Utilizes LESSS CSS & compiled via Node • behave great in the latest desktop browsers (as well as IE7!), tablet and smartphone browsers. • Skeleton • A small collection of CSS files that can help you rapidly develop sites that look beautiful at any size, be it a 17" laptop screen or an iPhone.

  12. Bootstrap Responsive Frameworks • 12-column responsive grid • As this is a 12-column grid, each .span* spans a number of those 12 columns, and should always add up to 12 for each row (or the number of columns in the parent). • EX: .span4 + .span8 = 12 total columns. Includes Base CSS, JavaScript Plugins & Form Controls

  13. Bootstrap Responsive Break Points

  14. Skeleton Responsive Frameworks • Skeleton has a familiar, lightweight 960 grid as its base, but elegantly scales down to downsized browser windows, tablets, mobile phone. • <!-- Give column value in word form (one, two..., twelve) --> • <div class=”twelve columns"> • <h1>Full Width Column</h1> • </div> Skeleton is not a UI framework. It's a development kit that provides the most basic styles as a foundation, but is ready to adopt whatever your design or style is.

  15. Skeleton Responsive Break Points

  16. 2014 Web Design Trends • “The frontend curious continue to push the bounds of the modern interface this year, combining HTML5/CSS and JavaScript.” • “Parallax scrolling websites - The mouse, tablet, touch, and pinch will be the future for how we experience things.” • “With Flash going extinct, JavaScript is bleeding into both front and back-end now. Frameworks will continue to pop out of the woodworks - If something can be built in JavaScript, it will be.” 11 web design trends I'd like to see in 2014 Pete Sena, 2/14/14 CreativeBloq.com
