Placeholder.js: The Ultimate Form User Experience for your customers

If your website or business relies on a form to capture details from potential
clients, then you’ll be acutely aware that everything from the speed of the form to the way it looks can affect the number of conversions, and subsequent customers, you’ll receive.

One incredibly important element with any form is clearly indicating what you want the user to do, every step of the way. Labels are key, but they take up vital space which can be sparse when designing attractive forms, especially on mobile.

It can be tempting to use placeholders, text displayed within the input, which
disappears once users start typing. This saves plenty of space, but means that
once the user begins typing, the label disappears and they no longer know what the purpose of the input box is.

Fully Customisable, Dynamic Placeholders

The solution: an animated placeholder, situated inside of inputs until that input is used, at which point the placeholder is replaced above. This offers the perfect User Experience, vital to optimising form conversions.

You can use the CDN here:



* Make sure to include Jquery in your HTML file prior to placeholder.js.
* Call the placeholder function inside $(document).ready(function(){…})
* Remember to add any styling attributes within quotation marks.
* The font-size of the placeholder is determined in accordance with the height of the input
* The use of pixels for styling is recommended
