目前我的网站是这样的：

Answer 1

您是否考虑过使用 css 网格？

.grid-container {
  display: inline-grid;
}

Answer 2

将height: 100%添加到.container并更改CSS。

* {
    outline: none;
    margin: 0;
    padding: 0;
    box-sizing: border-box;
    font-family: "Poppins", sans-serif;

    align-items: center;
    transition: 0.6s;
    padding: 40px 100px;

    transition: 0.6s;
}

header.sticky {
    padding: 5px 100px;
    background-color: #fff;
}

header.sticky .brand,
header.sticky ul li a {
