html - 使垂直调整大小固定

Question

我想知道如何在最小化浏览器高度时固定我的页面。截至目前，高度是敏感的，一切都被弄皱了。如果您调整 StackOverflow 的大小，高度将保持不变并且没有响应，这就是我想要的。我添加了一个基本形式的 fiddle 。

HTML:

<div class="contactform">
 <div class="bg">
  <h1><img src="https://i.imgur.com/F8fAFJH.png" alt="">Contact Form</h1>
   <form action=""
  method="POST">
    <input type="text" placeholder="Name" name="name">
    <input type="text" placeholder="Program of Interest" name="Program">
    <input type="text" placeholder="Gender" name="gender">
    <textarea placeholder="Questions/Concerns"></textarea>
    <input id="button" type="submit" value="Send">
   </form>
  </div>
</div>

CSS:

.contactform {
display: flex;
height: 100vh;
justify-content: center;
align-items: center;
background: #eee;
}

.contactform input {
display: block;
margin: 10px 0px;
height: 50px;
width: 400px;
background: transparent;
border: 0.1px solid;
outline-color: #eee;

input::placeholder {
color: #eee;
padding: 0px 10px
}

.bg {
width: 80vw;
height: 80vh;
background: #89c4f4;
position: relative;
position: fixed;
}

.bg  {
position: relative;
display: flex;
flex-direction: column;
justify-content: center;
align-items: center;
}

.bg h1 {
margin: 0;
color: #eee;
align-items: center;
justify-content: center;
display: flex;
}

.bg img {
height: 40px;
margin-right: 15px;
}

.bg textarea {
width: 400px;
height: 100px;
/max-width: 250px;
max-height: 200px;
background: transparent;
border: 0.1px solid #eee;
color: #eee;
outline-color: #eee;
}

textarea::placeholder {

padding: 0px 10px
}

#button {
background:;
color: #eee;
border: 0.1px solid #eee;
transition: 0.2s all ease-in-out;

尝试display:block

.menu_item{
    height: 15%;
    width: 45%;
    text-align: center;
}
.menu_icon{
    width:auto;
    height:100%;
}
.menu_item a {
  display:block;
}

<div class="menu_item">
    <a href="https://www.google.com">
        <img class="menu_icon" src="https://storage.googleapis.com/gweb-uniblog-publish-prod/static/blog/images/google-200x200.7714256da16f.png" alt="Templates"/>
        <span>Templates</span>
    </a>
</div>
