Setting Border-Right-Width with Length Units
The border-right-width property can be set using length units such as pixels (px), ems (em), and rems (rem). These units allow for precise control over the width of the right border.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<style>
div {
margin: 20px 7px;
}
.px-width {
border-right-width: 10px;
border-right-style: solid;
border-right-color: black;
padding: 10px;
width: 200px;
text-align: center;
}
.em-width {
border-right-width: 1em;
border-right-style: solid;
border-right-color: black;
padding: 10px;
width: 200px;
text-align: center;
}
.rem-width {
border-right-width: 1.5rem;
border-right-style: solid;
border-right-color: black;
padding: 10px;
width: 200px;
text-align: center;

<body>
<div class="px-width">10px Width</div>
<div class="em-width">1em Width</div>
<div class="rem-width">1.5rem Width</div>
</body>
</html>In this example, the .px-width, .em-width, and .rem-width classes use different length units to set the right border width. The units 10 pixels, 1 em, and 1.5 rems demonstrate how to use length units for precise control over the width of the right border.
Combining Border-Right-Width with Border-Right-Style and Border-Right-Color
The border-right-width property can be used in conjunction with border-right-style and border-right-color to create complex styles.

}
</style>
