Make placeholder text inside html text field blink

Before asking this question I searched a lot for this functionality but did'nt find any clue so that's why posting a new question.

So actually I have a placeholder text inside an html text field like this

<input type="text" class="timepicker" placeholder="Placeholder Text..." >

So what I want is to make this placeholder blink. So is it possible in html or by using jquery or javascript.
