how to customize the length of border-bottom
how to customize the length of border-bottom
I also saw @ Feng Hengzhi's answer, add to it
<div class='block'></block>
style
.block::after {
content: '';
width: 96%;
height: 1px;
display: block;
margin: 0 auto;
border-bottom: 1px solid rgba(151, 151, 151, 0.1);
} border-bottom cannot customize the length, but can only customize the width
if there is a need for custom length, it can be implemented with pseudo elements
