使弯曲线与CSS align-content属性对齐。您可以尝试运行以下代码来实现align-content属性。它在项目周围增加了空间：
<!DOCTYPE html>
<html>
<head>
<style>
.mycontainer {
display: flex;
background-color: orange;
align-content: space-between;
height: 150px;
width: 600px;
flex-wrap: wrap;
}
.mycontainer > div {
background-color: white;
text-align: center;
line-height: 40px;
font-size: 25px;
width: 100px;
margin: 5px;
}
</style>
</head>
<body>
<h1>Quiz</h1>
<div class = "mycontainer">
<div>Q1</div>
<div>Q2</div>
<div>Q3</div>
<div>Q4</div>
<div>Q5</div>
<div>Q6</div>
<div>Q7</div>
<div>Q8</div>
</div>
</body>
</html>
