Creating a blinking background color effect in CSS can be achieved using keyframes and animations. Here’s a simple example of how you can make a background color blink:
HTML:
html
<html>
<head>
<link rel="stylesheet" type="text/css" href="styles.css">
</head>
<body>
<div class="blinking-background">This has a blinking background</div>
</body>
</html>
CSS (styles.css):
css
/* Define a keyframes animation for the blinking effect */
@keyframes blink {
0% { background-color: red; }
50% { background-color: yellow; }
100% { background-color: red; }
}
/* Apply the animation to the element with a class */
.blinking-background {
animation: blink 2s linear infinite; /* 2s is the duration, you can adjust as needed */
text-align: center;
padding: 20px;
font-size: 18px;
}
In this code:
- We define a
@keyframesanimation called “blink” that alternates the background color between red and yellow. - We apply this animation to an element with the class “blinking-background” using the
animationproperty. The animation will last for 2 seconds (you can adjust the duration) and will repeat infinitely (infinite).
You can modify the colors, duration, and other styles to customize the blinking background effect to your preference.
