彈性布局(Flex)+骰子旋轉(zhuǎn)實(shí)例^v^

2020-3-1 前端達(dá)人

1. 語法是添加到父容器上的 display : flex;（彈性盒子的標(biāo)志哦！?。。? flex-direction: row; 布局的排列方向（主軸排列方向） row 默認(rèn)值，顯示為行。方向?yàn)楫?dāng)前文檔水平流方向，默認(rèn)情況下是從左往右。 row-reverse 顯示為行。但方向和row屬性值是反的 column 顯示為列 column-reverse 顯示為列。但方向和column屬性值是反的 flex-wrap : nowrap; 是否進(jìn)行換行處理。 nowrap; 默認(rèn)值，不換行處理 wrap; 換行處理 wrap-reverse; 反向換行 flex-flow : flex-direction flex-wrap 復(fù)合寫法 (是有順序的)。 justify-content ; 屬性決定了主軸方向上子項(xiàng)的對(duì)齊和分布方式。 flex-start ：子項(xiàng)都去起始位置對(duì)齊。 flex-end ：子項(xiàng)都去結(jié)束位置對(duì)齊。 center ：子項(xiàng)都去中心位置對(duì)齊。 space-between : 表現(xiàn)為兩端對(duì)齊。多余的空白間距在元素中間區(qū)域分配，兩邊沒寬。 space-around : 邊緣兩側(cè)的空白只有中間空白寬度一半即每個(gè)塊都有左右間距。 space-evenly :每個(gè)flex子項(xiàng)兩側(cè)空白間距完全相等。 align-items : 每一行中的子元素上下對(duì)齊方式。 stretch;默認(rèn)值，flex子項(xiàng)拉伸 flex-start;容器頂部對(duì)齊 center;容器居中對(duì)齊 flex-end;容器底部對(duì)齊 align-content : 跟justify-content相反的操作。側(cè)軸的對(duì)齊方式。(最少需要兩行才能看出效果，因?yàn)樗嵌嘈械囊粋€(gè)上下對(duì)齊方式) 默認(rèn)：多行下，有幾行就會(huì)把容器劃分為幾部分，默認(rèn)就是stretch拉伸的。值跟justify-content取值是相同的。 2. 語法是添加到子容器上的？ order : 排序(值越大越后) 0：默認(rèn)值 eg:1234 1：放在后面 eg:1342 -2：放在前面 eg:2134 flex-grow : 擴(kuò)展 ( 想看到擴(kuò)展的效果，必須有空隙 ) 0 : 默認(rèn)值 , 不去擴(kuò)展 0.5：占空隙的一半 1 : 去擴(kuò)展 , 會(huì)把空白區(qū)域全部沾滿（注：子元素會(huì)按照設(shè)置的比例值來分配空隙，如果比例值總和小于1，那么會(huì)有空隙，如果比例值總和大于等于1，那么就沒有空隙。） flex-shrink : 收縮正常默認(rèn)值是1 0表示不收縮，.5收縮小一些，2收縮大一些。（大小是跟正?？s放1進(jìn)行比較的） flex-basis : 跟flex-shrink/flex-grow很像。 flex-shrink/flex-grow是設(shè)置一個(gè)比例值，flex-basis是設(shè)置一個(gè)具體值。 flex : 一種復(fù)合寫法 flex-grow flex-shrink flex-basis flex:1; flex : 1 1 0 flex:0; flex : 0 1 0 algin-self: 跟align-items操作很像，區(qū)別就是只是針對(duì)某一個(gè)子項(xiàng)。

注：默認(rèn)情況下，在彈性盒子中的子元素的左右排列的。注：水平是主軸的時(shí)候：默認(rèn)情況下，當(dāng)寬高不寫的時(shí)候，寬度由內(nèi)容決定，高度由父容器決定。垂直是主軸的時(shí)候：默認(rèn)情況下，當(dāng)寬高不寫的時(shí)候，寬度由父容器決定，高度由內(nèi)容決定。注：當(dāng)子項(xiàng)的總寬度大于父容器的時(shí)候，會(huì)自動(dòng)收縮的（彈性的優(yōu)先級(jí)是大于自身固定大小的）注：當(dāng)子項(xiàng)的內(nèi)容已經(jīng)達(dá)到了父容器最小寬高的時(shí)候，就會(huì)出現(xiàn)溢出的現(xiàn)象。注：彈性布局中用的頻率比較多的語法： display : flex; flex-direction; justify-content; align-items; flex; 注：彈性布局的優(yōu)勢(shì)是做一維布局，網(wǎng)格布局的優(yōu)勢(shì)是做二維布局。
