如何启用flex布局

flex文档看完了,不知道flex布局如何启用

html code 

    <div class="home">
        <div class="home_header">
            <h1>this home is default</h1>
        </div>
        <div class="home_banner">
            <h1>this home is default</h1>
        </div>
        <div class="home_center">
            <h1>this home is default</h1>
        </div>
        <div class="home_contact">
            <h1>this home is default</h1>
        </div>
    </div>

css code   主要就是display :flex   就开启了flex布局,默认是横向的

<style>
    .home {
        display: flex;
        background-color: red;
        >div{
            height: 200px;
            width: 200px;
        }
        .home_header {
            background-color: yellow;
        }
        .home_banner {
            background-color: blue;
        }
        .home_center {
            background-color: yellow;
        }
        .home_contact{
            background-color: black;
        }
    }
</style>

界面效果,已经是横向布局了,因为是默认的横向布局
