Telephone Link Protocol
We've always been able to create links with protocols other than the usual HTTP, like mailto, skype, irc ,and more; they're an excellent convenience to visitors. With mobile phone browsers having become infinitely more usable, we can now extend that convenience to phone numbers:
tel protocol is used for phone numbers:
<a href="tel:18008675309">Call Jenny!</a>
If you'd like to create a link for SMS text messaging, that's easy enough too:
<a href="sms:18008675309">Text Jenny!</a>
sms protocol is used for text.
Many mobile browsers automatically linkify phone numbers on webpages but with the snippet above you can forcibly create phone links! Since said links don't work on desktop browsers, it's probably wise to create a JS snippet to replace spans with a given CSS class with phone links.
For maximum performance, we all know we must put our assets on CDN (another domain). Along with those assets are custom web fonts. Unfortunately custom web fonts via CDN (or any cross-domain font request) don't work in Firefox or Internet Explorer (correctly so, by spec) though...
Last week we created a very simple MooTools slideshow script. The script was very primitive: no events and no next/previous controls -- just cross-fading between images. This tutorial will take the previous slideshow script a step further by:
Adding "Next" and "Previous" controls.
