Examples

Basic example

This example applies special font and border styles when the placeholder is shown.

HTML

<input placeholder="Type something here!" />

CSS

input {
  border: 1px solid black;
  padding: 3px;
}

input:placeholder-shown {
  border-color: teal;
  color: purple;
  font-style: italic;
}

Result

Overflowing text

When form fields are too small, placeholder text can get cropped in an undesirable way. You can use the text-overflow property to alter the way overflowing text is displayed.

HTML

<input id="input1" placeholder="Name, Rank, and Serial Number" /> <br /><br />
<input id="input2" placeholder="Name, Rank, and Serial Number" />

CSS

#input2:placeholder-shown {
  text-overflow: ellipsis;
}
