How Can I Keep a Div's Border Length Shorter Than Its Width?

Maintaining Border Length within Div Width

In certain scenarios, you may encounter a situation where the border width of an element, such as a div, exceeds the width of the element itself. To address this, we can employ the following solution:

Utilizing Pseudoelements

Pseudoelements provide a way to add content to an element without affecting its actual content or structure. In this case, we can create a pseudoelement and position it within the div to simulate a shorter border.

Example Implementation

Consider the following code snippet:

div {
  width: 200px;
  height: 50px;
  position: relative;
  z-index: 1;
  background: #eee;
}

div:before {
  content: "";
  position: absolute;
  left: 0;
  bottom: 0;
  height: 1px;
  width: 100px;
  border-bottom: 1px solid magenta;
}

In this example, we create a pseudoelement with the :before selector. The pseudoelement is positioned at the bottom left corner of the div and given a width of 100px, which is less than the div width. We then apply a magenta border to the pseudoelement, creating the illusion of a border that is shorter than the div width while still maintaining the original div width.
