flex实验总结

1、父元素

.box{
     display:flex;
     flex-direction: column;//铺满垂直排列
     flex-direction: column-reverse;//铺满垂直反向排列
     flex-direction: row;//默认排列
     flex-direction: row-reverse;//反向排列
}

.box{
     display:flex;
     flex-wrap: nowrap;//不换行
     flex-wrap: wrap;//默认换行
     flex-wrap: wrap-reverse;//反向换行
}

.box {
  flex-flow: <flex-direction> || <flex-wrap>;//前面两种的简写默认值为row nowarp
}

.box{
     display:flex;
     justify-content: flex-start;//左对齐
     justify-content: flex-end;//右对齐
     justify-content: center;//居中
     justify-content: space-between;//平均分散
     justify-content: space-around;//平均外边距
}

.box{
     display:flex;
     align-items: stretch;//自定义铺满高度
     align-items: baseline;//文字按照基线对齐
     align-items: center;//垂直居中
     align-items: flex-end;//垂直下
     align-items: flex-start;//垂直上
}

.box{
     display:flex;
     align-content: stretch;//垂直铺满
     align-content: space-around;//同样边距
     align-content: space-between;//上下满外边距
     align-content: center;//垂直居中
     align-content: flex-end;//垂直居下
     align-content: flex-start;//垂直居上
}

2、子元素

.item {
  order: <integer>;//子元素的数值越大,越靠前
}

.item {
  flex-grow: <number>; //放大比例,根据数字放大
}

.item {
  flex-shrink: <number>;//缩小比例,根据数字缩小
}

.item {
  flex-basis: <length> | auto;//子元素的大小,可以设置宽度
}

.item {
  flex: none | [ <'flex-grow'> <'flex-shrink'>? || <'flex-basis'> ]//flex-grow, flex-shrink 和 flex-basis的简写
}

.item {
  align-self: auto | flex-start | flex-end | center | baseline | stretch;//允许单个项目有与其他项目不一样的对齐方式
}
