:placeholder-shown

This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The :placeholder-shown CSS pseudo-class represents any any <input> or <textarea> element that is currently displaying placeholder text.

/* Selects any element with an active placeholder */
:placeholder-shown {
  border: 2px solid silver;
}

Syntax

:placeholder-shown

Examples

Basic example

HTML

<input placeholder="Type something here!">

CSS

input {
  border: 2px solid black;
  padding: 3px;
}

input:placeholder-shown {
  border-color: silver;
}

Result

Overflowing text

On narrow screens such as smartphones, the width of search boxes and other form fields can get drastically shortened. This can result in their placeholder text getting cropped in an undesirable way. It is often useful to alter this behavior with the text-overflow property.

HTML

<input placeholder="Enter something into this field, if you please!">

CSS

input:placeholder-shown {
  text-overflow: ellipsis;
}

[1] Before Gecko 51.0 (Firefox 51.0 / Thunderbird 51.0 / SeaMonkey 2.48), Gecko implemented a -moz prefixed pseudo-class called :-moz-placeholder, which was later replaced by a ::-moz-placeholder pseudo-element. The standard pseudo-class got implemented in bug 1069012.

[2] Support for this pseudo-class has been requested at the Microsoft Edge Developer Feedback page.
