Isn’t left to right default of flex-box? Here’s my code.
<!doctype html>
<html>
<head>
<meta charset="UTF-8">
<title>Untitled Document</title>
<style>
div {
display: flex;
background-color: #999;
height: 200px;
width: 200px;
margin: 2%;
text-align: center;
}
#wrapper {
width: 80%;
height: 100%;
margin: auto;
background-color: white;
}
</style>
</head>
<body>
<div id="wrapper">
<div id="box1">1</div>
<div id="box2">2</div>
<div id="box3">3</div>
</div> <!--end of wrapper-->
</body>
</html>
