Bootstrap 4 .flex-fill类
使用flex-fill类在Bootstrap4中将flex项目设置为相等的宽度。
将<div>内的flex项目设置为flex-
<div class="d-flex mb-3 bg-primary"> <div class="p-2 flex-fill bg-danger">Example 1</div> <div class="p-2 flex-fill bg-warning">Example 2</div> <div class="p-2 flex-fill bg-info">Example 3</div> <div class="p-2 flex-fill bg-danger">Example 4</div> </div>
以下是显示flex-fill类的实现的示例-
示例
<!DOCTYPE html>
<html lang="en">
<head>
<title>Bootstrap Example</title>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.1.0/css/bootstrap.min.css">
<script src="https://cdn.staticfile.org/jquery/3.3.1/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.1.0/js/bootstrap.min.js"></script>
</head>
<body>
<div class="container mt-3">
<p>With flex-fill</p>
<div class="d-flex mb-3 bg-primary">
<div class="p-2 flex-fill bg-danger">Example 1</div>
<div class="p-2 flex-fill bg-warning">Example 2</div>
<div class="p-2 flex-fill bg-info">Example 3</div>
<div class="p-2 flex-fill bg-danger">Example 4</div>
</div>
<p>Without .flex-fill:</p>
<div class="d-flex mb-3 bg-secondary">
<div class="p-2 bg-danger">Example 1</div>
<div class="p-2 bg-warning">Example 2</div>
<div class="p-2 bg-info">Example 3</div>
<div class="p-2 bg-warning">Example 4</div>
