Spicing It Up With CSS3

CSS3

› Quick CSS Primer› CSS Specifications› Milestones in CSS› CSS3 In Depth› Quick jQuery Primer› Demos and Examples

Quick CSS Primer

CSS stands for Cascading Style Sheets

CSS is used to apply styling to mark-up elements

With presentation separate from content, the pages become more flexible

CSS Specification Stages

› The CSS specification goes through “stages” from the W3C.

› CSS3’s module’s stages varies significantly

› The only modules to have recommendation stage are Selectors Level 3, Colour, and Namespaces.

› Progress is relatively quick; a little over a year ago there was no modules at the Recommendation stage; only Selectors Level 3 was a Proposed Recommendation

Working Draft(WD)

Recommendation(REC)

Milestones in CSS: CSS1

› The CSS1 specification became a W3C Recommendation in December 1996

› In the year 2000, Internet Explorer 5.0 for Mac was the first browser to fully support the CSS1 specification

› CSS1 brought fourth primitive design attributes such as controlling fonts, colouring, aligning of text and elements, margins, borders, and padding

Milestones in CSS: CSS2

› The CSS2 specification became a W3C recommendation in May 1998

› CSS2 brought fourth improved printing abilities, Aural CSS (to assist visually disabled users by applying style sheets to oral presentations), and position attributes

Milestones in CSS: CSS2.1

› CSS 2.1 built upon CSS2; with its main goal being to correct a few errors found in CSS2

› CSS 2.1 reflected and focused on features that were widely implemented for both HTML and XML.

› CSS 2.1 just became a Recommendation in June of 2011

Milestones in CSS: CSS3

› CSS3 brings forth a lot of exciting new features, in a different approach than previous iterations.

› Like 2.0 to 2.1, CSS3 builds on top of 2.1

› Let’s examine CSS3 in depth…

CSS3 In Depth: What It Has To Offer› CSS3 contains vast array of new and improved capabilities,

most which go beyond just simple aesthetics.

› New changes have been implemented across almost every aspect of webpage styling scenarios, from fonts to media queries to animations and transitions

› Instead of having one monolithic release, CSS3 features have been broken down into modules.

CSS3 In Depth: Why Modules?

› CSS3 is being released in modules, instead of one monolithic release

› W3C can bring modules up to the Recommendation Level (REC) at different times, based on their priority

› Browser developers can implement CSS3 piece by piece, this helps speed up the overall implementation process

CSS3 In Depth: Why Modules?› Some technologies and browsers do not need to support the

full CSS3 specification.

› Text-reader only browsers do not need to wait and support background and borders to be CSS3 compatible, just as a visual-only browser does not need to support aural properties.

› Developers have the option of creating tailored subsets of CSS3 by selecting which modules they want to fully support.

CSS Modules› Currently 52 modules, though this can change as the

specification matures

› There are three priorities of completion; high, medium, and low

› Priorities are set based on community input and real-world application

› Each module is logically organized. i.e. anything to do with selectors is in the Selectors module

CSS3 In Depth: Current Support

IE9: A- FF 6.0.2 A- V. 14 - A V. 11.51: B+ V 5.1 - A

V8:DV7:D-V6:F

V5: B+V4: B+V3.6: B

V13: A-V12: A-V11: A-

V10: B-V9: CV8: C

V4:B

Based off historical support on a per-property basis; calculated to present then categorized by a standard grade letter.

So, how can we do CSS3 stuff now, and have all users experience it?...

Implementing CSS3 Today› Build your site with the bare minimums first

› All required functionality should be there› Required structural and visual elements implemented

› Add on visual value afterward with Progressive Enhancement

› Alternatively, you can do it in reverse – graceful degradation

› What if I need near consistent experience across the majority of browsers?

Implementing CSS3 Today› Browser Fallbacks

› Implement required functionally natively first› Provide “fallbacks” to browsers that do not support the

functionality natively

› Fallbacks can be done with› JavaScript alternatives› Proprietary functionality (i.e. IE’s “Filter”)› Conditional statements (and comments for IE!)› Pseudo effects (i.e. extra markup, images, etc.)

Quick jQuery Primer› We will use jQuery and several plug-ins to replicate CSS3

features that may not be supported in some of your target browsers.

› jQuery is a JavaScript library that allows you to quickly develop JavaScript based solutions

› It has great cross browser support including IE6+, FF2+, Safari 3+, and Opera 9+. So, let’s get in to some demos!

DemoCSS3

CSS3 Closing Statements› CSS3 will bring fourth a wealth of features that will make web

development easier and more efficient

› I estimate it will be three years until you can safely use CSS3 without fall-backs, taking into consideration user adoption of modern day browsers

› Until then, use alternatives such as the jQuery examples shown here to have a consistent user experience, or have the site enhance progressively/degrade gracefully

› Don’t wait for CSS3 to become a full recommendation, at the least, experiment with CSS3 today in subtle ways, i.e. text-shadows

Making Your Life Easier With Tools
