使用border-left-0类删除元素的左边框。
使用<div>内的类删除<div>的左边框-
<div class="one border border-left-0"> Removing left border </div>
在<div>类中还设置了“ one”类以对其进行样式设置-
<style>
.one {
width: 220px;
height: 220px;
margin: 50px;
}
</style>您可以尝试运行以下代码以使用border-left-0类-
<!DOCTYPE html>
<html lang="en">
<head>
<title>Bootstrap Example</title>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
