I need to build a web page for mobile devices. There's only one thing I still haven't figured out: how can I trigger a phone call through the click of text?
Is there a special URL I could enter like the mailto: tag for emails?
Device specific solution are not preferred.
I know iPhone automatically recognizes phone numbers and creates a link for this, but it would be great if this could be done for images too... and also for most mobile devices.
Most modern devices support the tel: scheme. So use <a href="tel:555-555-5555">555-555-5555</a> and you should be good to go.
If you want to use it for an image, the <a> tag can handle the <img/> placed in it just like other normal situations with : <a href="tel:555-555-5555"><img src="path/to/phone/icon.jpg" alt="Call 555-555-5555" /></a>
