CSS Rounded Corners is a technique used in web design to create rounded corners on HTML elements. It is a popular design trend that has been around for many years and is still widely used today. Rounded corners can be applied to a variety of HTML elements such as buttons, images, and divs. This technique is achieved using CSS properties and values.
The border-radius property is used to create rounded corners on HTML elements. This property takes a value that specifies the radius of the corners. The value can be specified in pixels, ems, or percentages. The border-radius property can be applied to all four corners of an element or to individual corners.
Here is an example of how to apply rounded corners to an HTML element:
<div style="border-radius: 10px;">
This div has rounded corners.
</div>
In the example above, the border-radius property is applied to the div element with a value of 10 pixels. This creates rounded corners on all four corners of the div element.
It is also possible to apply rounded corners to individual corners of an element. The border-top-left-radius, border-top-right-radius, border-bottom-left-radius, and border-bottom-right-radius properties can be used to specify the radius of each corner.
Here is an example of how to apply rounded corners to individual corners of an HTML element:
<div style="border-top-left-radius: 10px;
border-top-right-radius: 20px;
border-bottom-left-radius: 30px;
border-bottom-right-radius: 40px;">
This div has rounded corners on each corner.
</div>
In the example above, the border-top-left-radius property is set to 10 pixels, the border-top-right-radius property is set to 20 pixels, the border-bottom-left-radius property is set to 30 pixels, and the border-bottom-right-radius property is set to 40 pixels. This creates rounded corners on each corner of the div element.
It is also possible to create different shapes using the border-radius property. By specifying different values for each corner, it is possible to create shapes such as ovals and capsules.
Here is an example of how to create an oval shape using the border-radius property:
<div style="border-radius: 50% / 100%;">
This div has an oval shape.
</div>
In the example above, the border-radius property is set to 50% for the horizontal radius and 100% for the vertical radius. This creates an oval shape for the div element.
CSS Rounded Corners is a simple and effective technique for creating rounded corners on HTML elements. It is widely supported by modern web browsers and can be used to create a variety of shapes and designs.
