If you’re a smartphone user, you might get sensible to websites making phone numbers directly usable by the phone on the webpage.

it’s quite simple to code a phone sensitive link. Use this :

<a href="tel:1-555-555-555">call me directly</a>

Some phones or browsers might automatically detect phone numbers but could be mistaken by strings made of number which is not a phone number.

Then use this in conjunction with previous code to have full control on this behaviour in your web page.

     <!-- Turn off telephone number detection. -->

    <meta name = "format-detection" content = "telephone=no">
