CSS Border End and Start Radius

Introduction

The world of web design is ever-evolving, and one key aspect of ensuring that web pages look visually appealing is the use of CSS border properties. Among these properties, the border-radius plays a crucial role in creating rounded corners, enhancing the overall aesthetics of web elements. Recently, CSS introduced new properties like border-start-end-radius, which allows for more precise control over the rounded corners of elements.

Definition

The border-end-start-radius property refers to the ability to define the radius of the start and end corners of a box. In contrast to the standard border-radius, which applies a uniform radius to all corners of an element, border-end-start-radius focuses specifically on the start and end corners, enabling developers to create more tailored designs.

Browser Compatibility

When working with any CSS properties, it’s vital to consider browser compatibility. The border-end-start-radius property is relatively new, and while it is supported in most modern browsers, it might not be fully functional in older versions.

CSS Syntax

The CSS syntax for border-start-end-radius is straightforward:

  .example {
    border-start-end-radius: ;
  }
  

Here’s a practical example:

  .rounded-corners {
    border-start-end-radius: 15px 20px;
  }
  

Values

The border-start-end-radius property accepts various value types:

• Length units: pixels (px), ems (em), etc.
• Percentage: (%), defining the radius as a percentage of the box’s dimensions.
• Global values: inherit, initial, unset, etc.

This property allows you to specify different radius values for each corner. For example:

  .custom-radius {
    border-start-end-radius: 10px 20px 30px 40px;
  }
