How to create fade-in effect on page load using CSS ?
Use animation and transition property to create a fade-in effect on page load using CSS.
Method 1: Using CSS animation property:
A CSS animation is defined with 2 keyframes. One with the opacity set to 0, the other with the opacity set to 1. When the animation type is set to ease, the animation smoothly fades in the page. This property is applied to the body tag. Whenever the page loads, this animation would play and the page will appear to fade in. The time of the fade in can be set in the animation property.
Syntax:
html
body { animation: fadeInAnimation ease 3s; animation-iteration-count: 1; animation-fill-mode: forwards;}@keyframes fadeInAnimation { 0% { opacity: 0; } 100% { opacity: 1; }} |
Example:
html
<!DOCTYPE html><html> <head> <title> How to create fade-in effect on page load using CSS </title> <style> body { animation: fadeInAnimation ease 3s; animation-iteration-count: 1; animation-fill-mode: forwards; } @keyframes fadeInAnimation { 0% { opacity: 0; } 100% { opacity: 1; } } </style></head> <body> <h1 style="color: green"> GeeksForGeeks </h1> <b> How to create fade-in effect on page load using CSS </b> <p> This page will fade in after loading </p></body> </html> |
Output:
Method 2: Using the transition property and setting the opacity to 1 when the body is loaded:
In this method, the body can be set to the opacity 0 initially and the transition property is used to animate this property whenever it is changed. When the page is loaded, the opacity is set to 1 using the onload event. Due to the transition property, changing the opacity now will appear to fade in the page. The time of the fade in can be set in the transition property.
Syntax:
html
body { opacity: 0; transition: opacity 5s;} |
Example:
html
<!DOCTYPE html><html><head> <title> How to create fade-in effect on page load using CSS </title> <style> body { opacity: 0; transition: opacity 3s; } </style></head><body onload="document.body.style.opacity='1'"> <h1 style="color: green"> GeeksForGeeks </h1> <b> How to create fade-in effect on page load using CSS </b> <p> This page will fade in after loading </p></body></html> |
