As a web developer, you may often come across situations where you want to style the placeholder text of an input field to make it more visually appealing. Placeholder text can be used to provide helpful information to users about the expected value of a particular input field. Changing the color of placeholder text can not only help draw attention to it but also improve the overall user experience of your website.
In this article, we’ll walk you through some code examples to help you change the color of a placeholder with CSS and JavaScript.
Changing the color of a placeholder with CSS
CSS provides several ways to change the color of a placeholder. Here are some of the commonly used CSS properties that can be used to change the color of a placeholder:
- The ::placeholder pseudo-element selector
The ::placeholder pseudo-element selector can be used to style the placeholder text of an input field. To change the color of the placeholder, you can add the color property to the selector and set it to the desired color.
For example:
::placeholder {
color: red;
}
In this example, the placeholder text of the input field will be displayed in red.
- The :-webkit-input-placeholder and :-moz-placeholder selectors
Some browsers, such as Chrome and Firefox, use vendor-specific selectors to change the color of placeholder text. The :-webkit-input-placeholder and :-moz-placeholder selectors can be used to target the placeholder text of an input field in these browsers.
For example:
::-webkit-input-placeholder {
color: red;
}
::-moz-placeholder {
color: red;
}
In this example, the placeholder text will be displayed in red in Chrome and Firefox.
- The :-ms-input-placeholder selector
The :-ms-input-placeholder selector can be used to target the placeholder text of an input field in Microsoft Edge.
For example:
::-ms-input-placeholder {
color: red;
}
In this example, the placeholder text will be displayed in red in Microsoft Edge.
Changing the color of a placeholder with JavaScript
In addition to using CSS, you can also change the color of a placeholder with JavaScript. JavaScript can be used to dynamically set the color of a placeholder based on certain conditions.
Here’s an example of how you can change the color of a placeholder with JavaScript:
var input = document.getElementById("myInput");
input.placeholder = "Enter your text here";
if (condition) {
input.style.color = "red";
} else {
input.style.color = "black";
}
In this example, the color of the placeholder will be set to red if the specified condition is true. If the condition is false, the color of the placeholder will be set to black.
Tips for changing the color of a placeholder
When changing the color of a placeholder, there are a few tips that you should keep in mind:
- Make sure the color of the placeholder is readable
The most important thing to consider when changing the color of a placeholder is readability. Choose a color that provides enough contrast with the background color of the input field to ensure that the text is legible.
- Use a consistent color scheme
Try to use a color scheme that is consistent with the rest of your website. This will help create a cohesive design that is easy on the eyes.
- Test the color of the placeholder on multiple devices and browsers
Before deploying your changes, make sure to test the color of the placeholder on multiple devices and browsers to ensure that the changes are consistent across all platforms.
Conclusion
Changing the color of a placeholder on an input field can help improve the user experience of your website. Whether you use CSS or JavaScript, changing the color of a placeholder is an easy way to make your website more visually appealing. Keep in mind the tips listed above when changing the color of a placeholder to ensure that the text is readable and consistent across all devices and browsers.

When changing the color of a placeholder using CSS, it's important to note that not all browsers support the ::placeholder pseudo-element selector. In some cases, you may need to use vendor-specific selectors to ensure that the placeholder text is styled correctly across all browsers.
For example, let's say you wanted to change the color of the placeholder text to blue in Chrome and Firefox, but you weren't seeing the desired results when using the ::placeholder selector. You could try using the following CSS code instead:
::-webkit-input-placeholder {
/* set color to blue */
}
:-moz-placeholder {
/* set color to blue */
}
::-moz-placeholder {
/* set color to blue */
}
:-ms-input-placeholder {
/* set color to blue */
}
By using vendor-specific selectors, you can ensure that the placeholder text is styled consistently across all browsers, regardless of whether they support the ::placeholder selector.
Additionally, when changing the color of a placeholder using JavaScript, it's important to make sure that you're targeting the correct input field. In the example code provided earlier, the input field was targeted using its ID:
var input = document.getElementById("myInput");
If you're working with multiple input fields on a page, make sure to target the correct field using its ID, class, or name attribute to avoid applying the wrong styles to other elements.
It's also worth noting that some developers prefer to use a separate class for styling the placeholder text, rather than targeting it directly with CSS or JavaScript. This can help keep your code more modular and make it easier to update the styling later on.
For example, you could define a CSS class called "placeholder" and apply it to any input fields that you want to style:
.placeholder::placeholder {
color: blue;
}
By using a separate class for styling the placeholder text, you can easily update the color or other styles by changing the CSS rules for the "placeholder" class, rather than having to update each individual input field. This can save you time and make it easier to maintain your code over time.
