sass定義函式控制元素position的所有位置-超級方便
阿新 • • 發佈:2019-01-10
當頁面佈局用的比較多postition:absolute的時候,我們可以利用sass定義簡單的函式,實現多次操作。
html:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title></title>
<link rel="stylesheet" type="text/css" href="css/test1.css"/>
</head>
<body>
<div class="div1">div1</div>
<div class="div2">div2</div>
<div class="div3">div3</div>
<div class="div4">div4</div>
<div class="div5">div5</div>
<div class="div6">div6</div>
<div class="div7">div7</div>
<div class="div8">div8</div>
<div class="div9">div9</div>
</body>
</html>
scss:
@mixin qfun($w,$h,$vertical,$ver,$horizontal,$hor){
width: $w+px;
height: $h+px;
position: absolute;
@if ($vertical == t ){
top: $ver+px;
}@else if($vertical == b){
bottom: $ver+px;
}@else if($vertical == m){
top: 50%;
margin-top: -$w/2+px;
}
@if ($horizontal == l) {
left: $hor+px;
}@else if($horizontal == r){
right:$hor+px;
}@else if($horizontal == m){
left: 50%;
margin-left: -$h/2+px;
}
}
body{
position: relative;
width: 800px;
height: 800px;
border: 1px solid #000000;
.div1{
background: palegreen;
@include qfun(200,200,'t',12,'l',20);
}
.div2{
background: #0000FF;
@include qfun(200,200,'t',12,'m',0);
}
.div3{
background: wheat;
@include qfun(200,200,'t',12,'r',20);
}
.div4{
background: #F06633;
@include qfun(200,200,'m',0,'l',20);
}
.div5{
background: #FFC0CB;
@include qfun(200,200,'m',0,'m',0);
}
.div6{
background: #535F6D;
@include qfun(200,200,'m',0,'r',20);
}
.div7{
background: palegreen;
@include qfun(200,200,'b',12,'l',20);
}
.div8{
background: brown;
@include qfun(200,200,'b',12,'m',0);
}
.div9{
background: gold;
@include qfun(200,200,'b',12,'r',20);
}
}
如果沒有安裝scss檔案轉換成css檔案的同學需要安裝,然後進行轉換。
