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
}
