Flexbox - 自对齐

此属性类似于align-items，但在这里，它应用于各个弹性项目。

用法 -

align-self: auto | flex-start | flex-end | center | baseline | stretch;

此属性接受以下值 -

flex-start - 弹性项目将在容器的顶部垂直对齐。
flex-end - 弹性项目将在容器的底部垂直对齐。
flex-center - 弹性项目将在容器的中心垂直对齐。
Stretch - 弹性项目将垂直对齐，使其填充容器的整个垂直空间。
baseline - 弹性项目将在横轴的基线上对齐。

flex-start

将此值传递给属性 align-self 时，特定弹性项目将在容器的顶部垂直对齐。

Flex Align Self Start

以下示例演示了将值flex-start传递给align-self属性的结果。

<!doctype html>
<html lang = "en">
   <style>
      .box1{background:green;}
      .box2{background:blue;}
      .box3{background:red;}
      .box4{background:magenta; align-self:start;}
      .box5{background:yellow;}
      .box6{background:pink;}
      .box{
         font-size:35px;
         padding:15px;
      }
      .container{
         display:flex;

         border:3px solid black;
         align-items: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>
