How Should I Make My Cursor Blink Css

CSS Programming

In my experience as a web developer, I’ve come across various ways to make a cursor blink in CSS. If you’re looking to add a touch of interactivity or grab the user’s attention, making the cursor blink can be a great option.

Before we dive into the details, let’s first understand what the cursor is in CSS. The cursor is a graphical representation of the user’s pointing device, such as a mouse or touchpad. By default, the cursor is usually a solid arrow or hand symbol, depending on the context.

Using CSS Animations

One way to make the cursor blink is by utilizing CSS animations. CSS animations allow us to create smooth and dynamic effects on elements, and the cursor is no exception.

To start, we need to select the element that represents the cursor. In most cases, this is the HTML <body> element. We can then apply the animation to this element using the @keyframes rule.

Here’s an example of how you can make the cursor blink using CSS animations:

@keyframes blink {
0% { opacity: 0; }
50% { opacity: 1; }
100% { opacity: 0; }

body {
animation: blink 1s infinite;

In the example above, we define a keyframe animation called “blink” with three keyframes. At 0%, the opacity of the cursor is set to 0, making it invisible. At 50%, the opacity is set to 1, making the cursor visible. Finally, at 100%, the opacity is set back to 0, making the cursor invisible again.

We then apply this animation to the <body> element using the animation property. The animation is set to “blink” with a duration of 1 second and is set to repeat indefinitely using the “infinite” keyword.

Using JavaScript

If you prefer a more dynamic approach or need more control over the blinking behavior, you can use JavaScript to achieve the desired effect.

First, you’ll need to select the element representing the cursor, just like with CSS animations. Then, you can use JavaScript to toggle a CSS class that controls the visibility of the cursor.

Here’s an example of how you can make the cursor blink using JavaScript:

const cursor = document.querySelector('.cursor');

setInterval(() => {
}, 500);

In the example above, we select the element with the class “cursor” using JavaScript’s document.querySelector() method. We then use the setInterval() function to toggle the “blink” class every 500 milliseconds, making the cursor blink on and off.


Making the cursor blink in CSS can be a fun and effective way to add interactivity to your website. Whether you choose to use CSS animations or JavaScript, it’s important to consider the user experience and ensure that the blinking effect is not distracting or overwhelming.

Remember to test your cursor blinking implementation on different devices and browsers to ensure compatibility and accessibility. With some creativity and experimentation, you can create a cursor blinking effect that adds a personal touch to your website.
