    • Progressive Enhancement with CSS Or how I stopped worrying about IE6 and started loving CSS3 Nick Cowie Reformed web standards fascist nickcowie.com @ nickobec
    • Why build beautiful websites for just a few?
    • Just a few browsers? 10% Safari and Chrome 10% Firefox 3.5 5% Opera, Firefox 3 and others 15% IE8 47% IE7 13% IE6
    • CSS3 support 10% Now 20% in 6 months 40% in 2 years 90% in 4 years 100% Who knows?
    • Trust Stanford-Makovsy Web Credibility Study http://captology.stanford.edu/pdf/Stanford- MakovskyWebCredStudy2002-prelim.pdf
    • Validation -webkit-border-radius: 24px;
    • hacking CSS3 for IE filter: progid:DXImageTransform.Microsoft.Gradient (GradientType=0, StartColorStr='#ffffe8d8', EndColorStr='#ffce401c');
    • Example http://nickcowie.com/eotw
    • @font-face No longer restricted to web safe fonts Supported: FF3.5, SAF3, OP10, IE4 Unsupported: Next font in font stack IE: .eot format, loads all @font-face Problems: FOUT, failover
    • opacity Elements are translucent Supported: FF1.5, SAF1.2, OP9, IE5 Unsupported: Fully opaque IE: filter: alpha(opacity = 75); Problems: inherited WCAG2 colour contrast
    • RGBa Alpha channel on colours Supported: FF3, SAF3, OP10 Unsupported: ignores RGBa colour so set RGB colour before RGBa colour IE: only in special cases
    • RGBa backgrounds in IE hack Use conditional comments background-color: transparent; filter: progid:DXImageTransform.Microsoft.Gradient (GradientType=0, StartColorStr='#aaRRGGBB', EndColorStr='#aaRRGGBB') ;
    • border-radius Rounded corners on block elements Supported: FF3, SAF3 Unsupported: ignores IE: JavaScript or images Problems: max size in some webkit -moz-border-radius: 24px 0 24px 0; -webkit-border-radius: 24px 0 24px 0;
    • text-shadow Drop shadow for text Supported: FF3.5, SAF3, OP9.5 Unsupported: ignores IE: AVOID AT ALL COSTS filter: Shadow
    • box-shadow Drop shadow block elements Supported: FF3.5, SAF3, IE5 Unsupported: ignores IE: filter: progid:DXImageTransform.Microsoft.dropshadow (OffX=5, OffY=5, Color='#aaRRGGBB', Positive='true')"; Problems: inheritance in IE
    • transform Alter the appearance of elements: rotate, skew, flip ... Supported: FF3.5, SAF4 Unsupported: ignores IE: no Problems: getting too smart
    • transition Control the transition between two states Supported: FF3.7, SAF4 Unsupported: ignores IE: has it own transition, but ... Problems: getting too smart
    • gradients Gradients as block elements background Supported: SAF4, IE5 Unsupported: ignores Provide alternatives first. IE: filter: progid:DXImageTransform.Microsoft.Gradient (GradientType=0, StartColorStr='#aaRRGGBB', EndColorStr='#aaRRGGBB') ;
    • box-reflect Reflects a box element and contents Supported: SAF4 Unsupported: ignores Tricks: Add a css mask with a gradient
    • css-mask masks a box element and contents Supported: SAF4 Unsupported: ignores
    • Wait there are more I only chose a few to demonstrate a few, so get a copy of Safari or Chrome and go explore Surfin’ Safari or css3.info
