1 Enhancement & Degradation

Enhancement: reward

Enhancement: reward Visual treats for the more capable browser

Degradation: punishment

Degradation: punishment The removal of a treat

Degradation: punishment The removal of a treat The designer giveth and the designer taketh away!

Intention

Intention An awareness of browser capabilities and the appreciation that sites don’t need to look in the same in each one.

Intention An awareness of browser capabilities and the appreciation that sites don’t need to look in the same in each one. Safari IE6 Stuff and Nonsense stuffandnonsense.co.uk

Should websites look the same in all browsers?

2 A personal typographic journey

The early days... ... Dreamweaver... ... confusion!

The early days... ... Dreamweaver... ... confusion! The choice of fonts appeared to be system-wide

Note: CS3 panel shown Dreamweaver adobe.com/products/dreamweaver

The early days... ... Dreamweaver... ... confusion! The choice of fonts appeared to be system-wide It wasn’t clear about web-safe fonts

The early days... ... Dreamweaver... ... confusion! The choice of fonts appeared to be system-wide It wasn’t clear about web-safe fonts To an extent, Dreamweaver is still guilty

The allure of Flash

The allure of Flash You can use any font you liked

The allure of Flash You can use any font you like Layout freedom, a la print design (vs. HTML inconsistency)

The allure of Flash You can use any font you like Layout freedom, a la print design (vs. HTML inconsistency) Hence type can be presented as intended

Back to basics: HTML

Back to basics: HTML Accessible: screenreader-friendly and allows for resizing

Back to basics: HTML Accessible: screenreader-friendly and allows for resizing Updatable: the source text dictates the final render

Back to basics: HTML Accessible: screenreader-friendly and allows for resizing Updatable: the source text dictates the final render Simple: HTML and CSS — that’s it!

Image replacement

Image replacement PROS It looks good It gives control over other elements besides type

Image replacement PROS It looks good It gives control over other elements besides type CONS Difficult to update Inaccessible in some situations Potentially it differs from the source code

sIFR

sIFR at work on Jason Santa Maria’s site jasonsantamaria.com

sIFR The best of both worlds: the accessibility and ‘selectability’ of HTML but with (some of)* the benefits of Flash-based rendering. * = Layout is still determined by HTML

sIFR The best of both worlds: the accessibility and ‘selectability’ of HTML but with (some of)* the benefits of Flash-based rendering. Gracefully degrades for users without Flash / JS. * = Layout is still determined by HTML

sIFR The best of both worlds: the accessibility and ‘selectability’ of HTML but with (some of)* the benefits of Flash-based rendering. Gracefully degrades for users without Flash / JS. It’s brilliant, but essentially it’s a hack; not a solution. * = Layout is still determined by HTML

“ While sIFR gives us better typography today, it is clearly not the solution for the next 20 years. It is but a nice stopgap for people who value the importance of typography and don’t want to wait 1, 5, or 10 years for browser makers, OS vendors, and type foundries to figure out a better solution. The moment that happens however, sIFR will lift right ” out and give way to whatever other method is available. ~ Mike Davidson Mike Davidson, mikeindustries.com/blog/sifr

Font embedding

Font embedding Browser-supported font embedding is, I believe, the future of web typography.

@font-face

@font-face Originated in the CSS2 spec, despite its general association with CSS3.

4 We have issues

The issues

The issues Protection is needed for font foundries to counteract font piracy (as with EOT).

The issues Protection is needed for font foundries to counteract font piracy (as with EOT). How do we cope with licenses? Mozilla proposes including license data in HTTP headers.

The issues Protection is needed for font foundries to counteract font piracy (as with EOT). How do we cope with licenses? Mozilla proposes including license data in HTTP headers. More fonts need to be made available so that the choice can improve. In its current state, the limited choice is turning into not much more than an alternative list of web-safe fonts.

What needs to happen?

What needs to happen? Font foundries need to be protected by the technology, as they are with EOT.
