Enhancing Borders: Displaying Borders Only on Image Corners

In the realm of web design, creating visually appealing elements is paramount. One such element is the border, which adds a touch of definition to images and other elements. However, conventional borders often encompass the entire element's perimeter. Seeking a more nuanced approach, users have inquired about the possibility of restricting borders to only the corners of an image.

This seemingly intricate task is made possible through the implementation of innovative CSS techniques. A recent advancement focuses on utilizing the conical-gradient() function in conjunction with the -webkit-mask property.

img {
  --s: 50px; /* the size on the corner */

  padding: 20px; /* the gap between the border and image */
  border: 5px solid #B38184; /* the thickness and color */
  -webkit-mask:
    conic-gradient(at var(--s) var(--s),#0000 75%,#000 0)
    0 0/calc(100% - var(--s)) calc(100% - var(--s)),
    linear-gradient(#000 0 0) content-box;
}

By employing these CSS principles, developers can showcase borders that seamlessly complement the contours of images, highlighting important areas without overshadowing the content. Explore further possibilities in our comprehensive guide to creating corner-only borders.
