How Can I Customize the Text Input Caret in Different Browsers?

Styling the Text Input Caret

When working with text input fields, you may want to customize the appearance of the caret. The caret is the blinking cursor that indicates where text will be inserted when typing. While it's commonly assumed that the caret's appearance is controlled by the browser, there are actually techniques that can be employed to manipulate its design.

Answer

Internet Explorer and Edge

Unfortunately, you cannot directly customize the caret in Internet Explorer or Edge. The appearance of the caret is controlled by the browser and cannot be changed.

Chrome

For Google Chrome, you can use the caret-color property to change the color of the caret. Here's an example:

input {
  caret-color: green;
}

Firefox

Unfortunately, Firefox does not offer any built-in styling options for the text input caret.

Alternative Method: Simulating Caret Changes

If you need finer control over the caret's appearance, one workaround is to simulate the caret using JavaScript and CSS. This technique involves creating a hidden textarea and simulating keystrokes to mimic the behavior of a text input.

2018 Update

A newer CSS property, caret-color, has emerged that directly affects the color of the caret in input fields. However, it's important to note that support for this property is still limited and may not work in all browsers.
