网格布局
如下代码，使用网格布局来实现页面
<!doctype html>
<head>
<style>
:root {
box-sizing: border-box;
}
*,
::before,
::after {
box-sizing: inherit;
}
body {
background-color: #709b90;
font-family: Helvetica, Arial, sans-serif;
}
.container {
display: grid;
grid-template-columns: 2fr 1fr;
grid-template-rows: repeat(4, auto);
grid-gap: 1.5em;
max- 1080px;
margin: 0 auto;
}
header,
nav {
grid-column: 1 / 3;
grid-row: span 1;
}
.main {
grid-column: 1 / 2;

}
.sidebar-top {
grid-column: 2 / 3;
grid-row: 3 / 4;
}
.sidebar-bottom {
grid-column: 2 / 3;
grid-row: 4 / 5;
}
.tile {
