Introduction to CSS Curved Border
Curved border in CSS can be done by border-radius property. Border-radius property removes the corners of the elements and replaces with a certain radius. Based on the given border-radius value curved border shape depends. Border-radius values can be in pixels or percentages. You can apply border-radius to all four sides of elements such as images, buttons, paragraphs, etc. You can also simultaneously apply border-radius on two sides, like a top, bottom, left and right.
Real-Time Usage: Beautifying images, buttons, headers, paragraphs, etc., with the required radius by border-radius property.
How does Curved Border Work in CSS?
As discussed above, the curved border can be generated with a border radius. Observe the below syntaxes:
Syntax 1:
div
{
border-radius: 10px;
}border-radius: Can be applied to the top, right, bottom, and left sides.
Syntax 2:
div
{
border-radius: 10px 10px 10px 10px;
}Explanation: If we apply border-radius with four values, then the first value is for the top-left corner, the second value is for the top-right corner, the third value is for the bottom-right corner, and the fourth value is for the bottom-left corner applied respectively.
Syntax 3:
div
{
border-radius: 10px 10px 10px;
}Explanation: If we apply border-radius with three values, the first value is for the top-left corner, the second value is for the top-right corner and bottom-right corner, and the third value is for the bottom-left corner applied, respectively.
Syntax 4:
div
{
border-radius: 10px 10px;
}Explanation: If we apply border-radius with two values, the first is for the top-left corner and top-right corner, and the second is for the bottom-right corner and bottom-left corner applied, respectively.
Syntax 5:
div
{
border-radius: 10px;
}Explanation: If we apply border-radius with a single value, then apply it for all four sides equally. If we want to apply only margin side border-radius, then CSS provides predefined properties. border-top-left-radius: 10px: apply border-radius 10px to top-left side.
Syntax 6:
div
{
border-top-left-radius: 10px;
}border-top-right-radius: 10px: apply border radius 10px to top-right side.
Syntax 7:
div
{
border-top-right-radius: 10px;
}border-bottom-left-radius: 10px: apply border radius 10px to bottom-left side.
Syntax 8:
div
{
border-bottom-left-radius: 10px;
}border-bottom-right-radius: 10px: apply border radius 10px bottom-right side.
Syntax 9:
div
{
border-bottom-right-radius: 10px;
