Flexbox - 对齐内容
如果 flex-container 有多行(即 flex-wrap: wrap),align-content 属性将定义容器内每行的对齐方式。
用法 −
align-content: flex-start | flex-end | center | space-between | space-around | stretch;
此属性接受以下值 −
stretch − 内容中的行将拉伸以填满剩余空间。
flex-start − 内容中的所有行都打包在容器的开头。
flex-end −内容中的所有行都打包在容器的末尾。
center − 内容中的所有行都打包在容器的中心。
space-between − 额外的空间均匀分布在行之间。
space-around −额外的空间均匀分布在行之间,每行(包括第一行和最后一行)周围的空间相等。
center
将此值传递给属性 align-content 后,所有行都会排列在容器的中心。

以下示例演示了将值 center 传递给 align-content 属性的结果。
<!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:25px; padding:15px; width:43%; } .container{ display:flex; height:100vh; flex-wrap:wrap; align-content:center; } </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 −
flex-start
将此值传递给属性 align-content 后,所有行都将打包在容器的开头。

以下示例演示了将值 flex-start 传递给 align-content 属性的结果。
<!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:25px; padding:15px; width:40%; } .container{ display:flex; height:100vh; flex-wrap:wrap; align-content:flex-start; } </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 −
flex-end
将此值传递给属性 align-content 后,所有行都会被打包到容器的末尾。

以下示例演示了将值 flex-end 传递给 align-content 属性的结果。
<!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:25px; padding:15px; width:40%; } .container{ display:flex; height:100vh; flex-wrap:wrap; align-content:flex-end; } </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 −
stretch
将此值传递给属性 align-content 后,线条将拉伸以填满剩余空间。

以下示例演示了将值 stretch 传递给 align-content 属性的结果。
<!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:25px; padding:15px; width:40; } .container{ display:flex; height:100vh; flex-wrap:wrap; align-content:stretch; } </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 −
space-around
将此值传递给属性 align-content 后,额外的空间将均匀分布在行之间,每行周围的空间相等(包括第一行和最后一行)。

以下示例演示了将值 space-around 传递给 align-content 属性的结果。
<!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:25px; padding:15px; width:40%; } .container{ display:flex; height:100vh; flex-wrap:wrap; align-content:space-around; } </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 −
space-between
将此值传递给属性 align-content 后,额外的空间将均匀分布在行之间,其中第一行将位于容器的顶部,最后一行将位于容器的底部。

以下示例演示了将值 space-between 传递给 align-content 属性的结果。
<!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:25px; padding:15px; width:40%; } .container{ display:flex; height:100vh; flex-wrap:wrap; align-content:space-between; } </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>
