使用 CSS3 包装弹性项
要使用 CSS3 包装弹性项,请使用 flex-wrap 属性。将值包装设置成能够包装。
包装弹性项
在这个示例中,我们使用 flex-wrap: wrap 包装弹性项。以下是我们的弹性容器:-
<div class="container"> <div class="first">First Div</div> <div class="second">Second Div</div> <div class="third">Third Div</div> </div>
我们对弹性容器进行了如下样式设置。flex-wrap 被设置成包装弹性项 -
.container {
height: 300px;
display: flex;
width: 300px;
border: 2px solid red;
flex-wrap: wrap;
}
示例
以下是使用 CSS3 包装弹性项的代码 -
<!DOCTYPE html>
<html>
<head>
<style>
body {
font-family: "Segoe UI", Tahoma, Geneva, Verdana, sans-serif;
}
.container {
height: 300px;
display: flex;
width: 300px;
border: 2px solid red;
flex-wrap: wrap;
}
div {
width: 150px;
height: 100px;
color: white;
text-align: center;
font-size: 20px;
}
.first {
background-color: rgb(55, 0, 255);
}
.second {
background-color: red;
}
.third {
background-color: rgb(140, 0, 255);
}
</style>
</head>
<body>
<h1>Flex wrap example</h1>
<div class="container">
<div class="first">First Div</div>
<div class="second">Second Div</div>
<div class="third">Third Div</div>
</div>
</body>
</html>
包装弹性项并在项的周围设置相等的空间
在这个示例中,我们将使用 flex-wrap 包装弹性项 -
flex-wrap: wrap;
为了在项周围设置相等的空间,我们使用了 justify-content 属性 -
justify-content: space-evenly;
示例
让我们看下示例 -
<!DOCTYPE html>
<html>
<head>
<style>
body {
font-family: "Segoe UI", Tahoma, Geneva, Verdana, sans-serif;
}
.container {
display: flex;
flex-wrap: wrap;
justify-content: space-evenly;
background-color: lightblue;
}
.container1 {
align-self: flex-start;
display: flex;
background-color: rgb(71, 30, 255);
width: 200px;
margin: 20px;
}
.container1 > div {
background-color: #f1f1f1;
margin: 10px;
padding: 10px;
font-size: 30px;
}
.container2 {
display: flex;
background-color: rgb(14, 126, 79);
width: 200px;
justify-content: center;
align-self: flex-start;
margin: 20px;
}
.container2 > div {
background-color: #f1f1f1;
margin: 10px;
padding: 10px;
font-size: 30px;
}
.container3 {
display: flex;
flex-direction: column;
background-color: rgb(168, 60, 10);
width: 200px;
align-items: center;
margin: 20px;
}
.container3 > div {
background-color: #f1f1f1;
margin: 10px;
padding: 10px;
width: 20px;
font-size: 30px;
}
</style>
</head>
<body>
