怎样用hbuilder制作banner层和middle层，需要大概的代码

img

<html lang="en">

<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">

</head>

<body>
    <div class="banner">图片</div>
    <div class="navbar">
        <div>1</div>
        <div>2</div>
        <div>3</div>
        <div>4</div>
        <div>5</div>
        <div>6</div>
        <div>7</div>
        <div>8</div>
    </div>
    <div class="middle">
        <div>1</div>
        <div>2</div>
        <div>3</div>
    </div>

</body>

</html>
<style type="text/css">
    .banner {
        border: 1px solid;
        height: 80px;
    }

    .navbar {
        display: flex;
        justify-content: center;
        border: 1px solid;
    }

    .navbar div {
        width: 100px;
        line-height: 40px;
    }

    .middle {
        display: flex;
        justify-content: center;
    }

    .middle div {
        width: 100px;
        height: 100px;
        border: 1px solid;
    }
</style>

大概这么个意思

div+flex布局 就行
