How to Dynamically Alter Placeholder Text Color Using JavaScript

When working with text input fields, you may occasionally need to modify the color of their placeholder text. While searching online may yield limited results, this guide will provide a comprehensive solution using JavaScript and CSS variables.

To begin, target the desired input field in your HTML code:

<input placeholder="Placeholder Text">

In your CSS, define the placeholder style using a CSS variable:

::placeholder {
  color: var(--placeholder-color, black);
}

Now, in your JavaScript code, define a function to update the placeholder color:

function updatePlaceholderColor(newColor) {
  document.querySelector('input[placeholder]').style.setProperty('--placeholder-color', newColor);
}

When you call updatePlaceholderColor(newColor), the newColor value will be applied to the placeholder text color. This method allows you to dynamically change the color from your JavaScript code.

For example, you can create a color picker that updates the placeholder color based on the selected value:

colorPicker.addEventListener('change', function() {
  updatePlaceholderColor(this.value);
});

Using CSS variables and JavaScript, you can effortlessly customize the placeholder text color of your input fields, providing enhanced flexibility and user experience.
