Experimenting with flex-box. Some how my boxes align top to bottom and not left to right.

Isn’t left to right default of flex-box? Here’s my code.

<!doctype html>
<meta charset="UTF-8">
<title>Untitled Document</title>
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;

<div id="wrapper">
<div id="box1">1</div>
<div id="box2">2</div>
<div id="box3">3</div>
</div> <!--end of wrapper-->

You must apply display: flex to your wrapper.
