Not showing placeholder for input type="date" field

I am doing a phonegap app. When I am trying type="date" input field as shown below, it shows date picker in iPhone as I expected but it doesn't show the placeholder I have given. I found the same issue here in SO, but no solution anywhere.

 <input placeholder="Date" class="textbox-n" type="date" id="date">

It may not be appropriate... but it helped me.

<input placeholder="Date" class="textbox-n" type="text" onfocus="(this.type='date')" id="date">

If you use mvp's method but add the onblur event to change it back to a text field so the placeholder text appears again when the input field looses focus. It just makes the hack a little bit nicer.

<input placeholder="Date" class="textbox-n" type="text" onfocus="(this.type='date')" onblur="(this.type='text')" id="date" />

Hope this helps.

I ended up using the following.

Regarding Firefox comment(s): Generally, Firefox will not show any text placeholder for inputs type date. But as this is a Cordova/PhoneGap question this should be of no concern (Unless you want to develop against FirefoxOS).

input[type="date"]:not(.has-value):before{
  color: lightgray;
  content: attr(placeholder);
}

<input type="date" placeholder="MY PLACEHOLDER" onchange="this.className=(this.value!=''?'has-value':'')">

As of today (2016), I have successfully used those 2 snippets (plus they work great with Bootstrap4).

Input data on the left, placeholder on the left

input[type=date] {
  text-align: right;
}

input[type="date"]:before {
  color: lightgrey;
  content: attr(placeholder) !important;
  margin-right: 0.5em;
}

Placeholder disappear when clicking

input[type="date"]:before {
  color: lightgrey;
  content: attr(placeholder) !important;
  margin-right: 0.5em;
}
input[type="date"]:focus:before {
  content: '' !important;
}
