The caret shorthand CSS property sets the appearance and behavior of the insertion caret in a single declaration.

Try it

caret: red;
caret: block manual;
caret: underscore auto green;
caret: bar manual orange;
<section class="default-example container" id="default-example">
  <div>
    <label for="example-element">Edit text field:</label>
    <input id="example-element" type="text" value="Sample text" />
  </div>
</section>
div {
  text-align: left;
}

#example-element {
  font-size: 1.2rem;
  padding: 8px;
  width: 300px;
}

Constituent properties

This property is a shorthand for the following CSS properties:

Syntax

css
/* Individual values */
caret: red; /* caret-color only */
caret: block; /* caret-shape only */
caret: manual; /* caret-animation only */

/* Two values */
caret: red manual; /* caret-color + caret-animation */
caret: block auto; /* caret-shape + caret-animation */
caret: underscore orange; /* caret-shape + caret-color */

/* Three values */
caret: bar manual red; /* caret-shape + caret-animation + caret-color */
caret: block auto #00ff00; /* caret-shape + caret-animation + caret-color */

/* Global values */
caret: inherit;
caret: initial;
caret: revert;
caret: revert-layer;
caret: unset;

The caret property is specified as one, two, or three values from the constituent properties. Values can be specified in any order, and omitted values are set to their initial values.

Values

caret-color

Sets the color of the caret.

caret-animation

Controls whether the caret blinks.

caret-shape

Sets the visual shape of the caret.

Description

The caret shorthand allows you to set multiple caret properties in a single declaration, making it convenient to customize the complete appearance and behavior of the insertion caret.

Value resolution

When values are omitted from the shorthand, they reset to their initial values:

  • caret-color: auto (resolves to currentColor).
  • caret-animation: auto (caret blinks).
  • caret-shape: auto (browser-determined shape).

Order independence

Unlike some CSS shorthands, the caret property accepts values in any order. The browser determines which value applies to which property based on the value type:

  • <color> values apply to caret-color.
  • auto/manual keywords apply to caret-animation.
  • Shape keywords (bar, block, underscore) apply to caret-shape.

Examples

Retro terminal with animated caret

This example creates a vintage terminal interface using the caret shorthand to combine multiple caret properties, demonstrating how it replaces older border-based techniques.

The main advantage of the caret shorthand is combining multiple properties in one declaration. Here we set the shape to block, disable default blinking, and set the color to green, all in a single line.

HTML

html
<label for="terminal">Enter a command</label>
<div class="old-screen">
  <span>></span>
  <textarea id="terminal" class="terminal-input"></textarea>
</div>

CSS

css
.terminal-input {
  caret: block manual green;
  animation: vintage-caret 2s infinite;
}

@keyframes vintage-caret {
  from,
  50% {
    caret-color: green;
  }
  75%,
  to {
    caret-color: transparent;
  }
}
