The task is to animate the shape of all corners using the CSS. Cascading Style Sheets(CSS) is a language used to give style to the web page. The shape of corners can be defined and animated using CSS by utilizing the “border-radius” property. By specifying a value for “border-radius” in conjunction with CSS animations or transitions, the corners of an element can be dynamically transformed and animated.
Properties used: In this article, we will make use of the following properties
- animation: This property is used to change one form of the style to another.
- border-bottom-right-radius: This property is used to define the radius of the bottom-right corner.
- border-bottom-left-radius: This property is used to define the radius of the bottom-left corner.
- border-top-left-radius: This property is used to define the radius of the top-left corner.
- border-top-right-radius: This property is used to define the radius of the bottom-left corner.
- @Keyframes rule: This rule is used to animate the changes gradually from the current style to the new style at certain times.
Approach:The first task is to create the basic HTML page structure with the style element. After creating the style tag into the head tag, we will add the border-bottom-right-radius, border-bottom-left-radius, border-top-left-radius, border-top-right-radius properties to style all the corners and also provide the animation with the help of the animation property.
Example: In this example, we are using the above-explained approach.
<!DOCTYPE html> < html >
< head >
< style >
body {
text-align: center;
}
h2 {
margin-left: 10px;
margin-top: 30px;
margin-right: 15px;
background-color: lightgreen;
border: 5px solid green;
height: 100px;
animation: mymove 5s infinite;
}
@keyframes mymove {
60% {
border-bottom-right-radius: 60px;
border-top-left-radius: 60px;
border-top-right-radius: 60px;
border-bottom-left-radius: 60px;
}
}
</ style >
</ head >
< body >
< h2 >GeeksforGeeks</ h2 >
</ body >
</ html >
