在不同的移动屏幕中缩放网格

Question

我正在创建UI(标题、网格和按钮(，希望它在每个移动屏幕上都是一样的。以下是目前不同手机屏幕的截图：

三星S5

Pixel 2 XL

Ipad

我希望Pixel 2 XL和Ipad中的网格能够像Samsung S5那样缩放，即在这两张屏幕截图中，Exit按钮后有相当大的空白。

我希望这些按钮位于屏幕底部，页眉位于最顶部，其余部分由网格覆盖。

我觉得我在分配网格的height时做错了什么——如果我把它调高，那么按钮就会超出Samsung S5。有人能帮我吗？

给你的.component一个height: 100vh，并调整每个孩子(.header、.grid和.buttonAndInput(的

html,
body {
margin: 0;
}
.component {
height: 100vh;
text-align: center;
display: flex;
flex-direction: column;
}
.header {
padding: 1rem 0;
flex: 1 1 10%;
}
.grid {
width: 90%;
margin: 0 auto;
flex: 1 1 70%;
display: flex;
flex-wrap: wrap;
}
.box {
flex: 1 1 50%;
position: relative;
cursor: pointer;
}
.box .inner {
border-radius: 5px;
margin: 5px;
border: 1px solid #d2d2d2;
position: absolute;
left: 0;
right: 0;
bottom: 0;
top: 0;
display: flex;
align-items: center;
justify-content: center;
}
.buttonAndInput {
width: 100%;
flex: 1 1 20%;
padding-top: 0.5rem;
}
.button {
margin-top: 0.5rem;
}
.button-continue {
height: 35px;
width: 250px;
}
.link {
margin-top: 0.5rem;
