Call or text from a mobile device using very simple markup

At my latest presentation (at upNorth web conferce in Greece), people were impressed with some very trivial markup that can add many points to your mobile site (and not only) with minimum effort. With the below very easy to implement markup you can make your site interact with the device in order to make phone calls and/or send sms (I only tested it with iPhone but I believe its working on other devices as well)!

See the Pen Call or text from a mobile device using very simple markup by John Tsevdos (@tsevdos) on CodePen

The above enhancements, together with a custom iOS home screen icon/image, are probably the easiest markup implementations that give to your mobile site/app many more extra points! If you’ve tested the above example with other devices (android, windows, blackberry, etc.) please confirm that it’s working (just leave a comment)…

Beginning HTML ordered lists with numbers other than 1

Yes it is possible and easy! You only have to use the (rare/unknown?) start attribute at your ordered list element (see example below).

<ol start="4">  
    <li>list item 1</li>  
    <li>list item 2</li>  
    <li>list item 3</li>  
    <li>list item 4</li>  
    <li>list item 5</li>  
</ol> Check out this Pen!

And guess what? It works with negative numbers as well!
