通常，如果容器的空间不足，其余的flex项将被隐藏，如下所示.
flex-wrap 属性用于指定flex-container是单行还是多行的控件.
用法 :
flex-wrap: nowrap | wrap | wrap-reverse flex-direction: column | column-reverse
此属性接受以下值 :
wrap : 如果空间不足，容器的元件(flexitems)将从上到下包裹成额外的柔性线.
包装 - 反转 : 如果空间不足，容器的元件(flex-items)将从底部到顶部包裹成额外的柔性线.
现在，我们将看到如何使用 wrap 属性和示例.
传递值换行到属性 flex-wrap ，容器的元素从左到右水平排列，如下所示.
以下示例演示了将值 wrap 传递给
<!doctype html>
<html lang = "en">
<style>
.box1{background:green;}
.box2{background:blue;}
.box3{background:red;}
.box4{background:magenta;}
.box5{background:yellow;}
.box6{background:pink;}
.box{
font-size:35px;
padding:15px;
width:100px;
}
.container{
display:flex;
border:3px solid black;
flex-direction:row;
flex-wrap:wrap;
}
</style>
<body>
<div class = "container">
<div class = "box box1">One</div>
<div class = "box box2">two</div>
<div class = "box box3">three</div>
<div class = "box box4">four</div>
<div class = "box box5">five</div>
<div class = "box box6">six</div>
</div>
</body>
</html>它将产生以下结果 :
在将值wrap-reverse传递给属性flex-wrap时，容器的元素从左到右水平排列，如下所示。
以下示例演示将值wrap-reverse传递给flex-wrap属性的结果。 在这里，我们使用flex-direction值行创建六个具有不同颜色的框。
<!doctype html>
<html lang = "en">
<style>
.box1{background:green;}
.box2{background:blue;}
.box3{background:red;}
.box4{background:magenta;}
.box5{background:yellow;}
.box6{background:pink;}
.box{
font-size:35px;
padding:15px;
width:100px;
}
.container{
display:flex;
border:3px solid black;
flex-direction:row;
flex-wrap:wrap-reverse;
}
</style>
<body>
<div class = "container">
<div class = "box box1">One</div>
<div class = "box box2">two</div>
<div class = "box box3">three</div>
<div class = "box box4">four</div>
<div class = "box box5">five</div>
<div class = "box box6">six</div>
</div>
</body>
</html>在将值包装传递给属性flex-wrap并将值列传递给属性flex-direction时，容器的元素从左到右水平排列，如下所示。
以下示例演示将值包装传递给flex-wrap属性的结果。 在这里，我们使用flex-direction value列创建六个具有不同颜色的框。
<!doctype html>
<html lang = "en">
<style>
.box1{background:green;}
.box2{background:blue;}
.box3{background:red;}
.box4{background:magenta;}
.box5{background:yellow;}
.box6{background:pink;}
.box{
font-size:35px;
padding:15px;
width:100px;
}
.container{
display:flex;
border:3px solid black;
flex-direction:column;
flex-wrap:wrap;
height:100vh;
}
</style>
<body>
<div class = "container">
<div class = "box box1">One</div>
<div class = "box box2">two</div>
<div class = "box box3">three</div>
<div class = "box box4">four</div>
<div class = "box box5">five</div>
<div class = "box box6">six</div>
</div>
</body>
</html>在将值wrap-reverse传递给属性flex-wrap并将value列传递给属性flex-direction时，容器的元素从左到右水平排列，如下所示。
以下示例演示将值wrap-reverse传递给flex-wrap属性的结果。 在这里，我们创建了六个具有不同颜色的框和带有flex-direction值列的框。
<!doctype html>
<html lang = "en">
<style>
.box1{background:green;}
.box2{background:blue;}
.box3{background:red;}
.box4{background:magenta;}
