flex佈局,一邊定寬的寬度會變化的問題
解決:flex:1 這邊設置width爲0css

使用 overflow: hidden; 清除浮動時,不能定高 <!DOCTYPE html> <html> <head> <title></title> <style type="text/css"> #div1{ width: 200px; /*height: 50px;*/ overflow: hidden; padding: 10px 20px 20px 10px; background: red; margin: 0 auto; } #div2{ width: 100px; height: 100px; background: green; float: left; } </style> </head> <body> <div id="div1" > <div id="div2" ></div> </div> </body> </html>
總結:當父元素的高度是靠子元素撐開的時候,子元素浮動時,
則在父元素使用overflow: hidden能夠清除浮動,使得父元素的高度依舊是靠子元素撐開。
當父元素自身設置了height屬性值,
則在父元素使用overflow: hidden能夠使子元素超出父元素的那部分隱藏。html
//給父元素相對定位 li:after{ content: ''; /*CSS僞類用法*/ position: absolute; /*定位背景橫線的位置*/ top: 97%; left: 20%; background: #fff; /*寬和高作出來的背景橫線*/ width: 60%; height: .1rem; }

//水平和垂直方向都居中 //定位的時候用 transform: translate(-50%,-50%)

若是不想出現滾動條,外面能夠再套一層,,設置高度,而後overflow:hiddenweb
