vue 应用程序不会在媒体查询中增长到 100% 高度

Question

大家好，我在几个页面上使用了我的 vue 路由器，页面上的主容器不会使用此媒体查询将高度设置为 100%

@media screen and (min-width: 700px) {
  #signinContainer {
    height: 100%;
  }
  #signinContainer {
  height: 520px;
  }
  #mainContainer{
    height: 100%;
  }
}

我已经尝试将路由器组件和应用程序本身设置为 100% 高度，但这不起作用，我想避免只将其设置为 700px，因为我希望它根据需要动态增长和收缩

希望有人能看出我做错了什么。我之前遇到过同样的宽度问题，更改视图中的 div 宽度修复了它，但我到目前为止尝试的高度并非如此

这是问题的图片

这是我的组件

<template>
  <div id="mainContainer">
    <div class="topContainer">
      <img src="../assets/svg/logo_big.svg" height="45px" width="110" alt="flyex logo">

      <h6 id="language">English <small id="dropDownArrow">&#x25BC;</small></h6>
      </section>
    </div>

    <div id="signinContainer">
      <form @submit.prevent="handleSubmit">
        <h4>Sign In</h4>
        <input type="email" v-model="email" placeholder="  Email" />
        <input type="password" v-model="password" placeholder="  Password" />
        <div id="formButton">

这是我渲染组件的视图

<template>
    <div>
    <Signin/>
    </div>
</template>

<script>
// @ is an alias to /src
import Signin from '@/components/Signin.vue'

export default {
  name: 'signin',
  components: {
    Signin
  }
}
</script>

<style scoped>

div{
  width: 100%;
  height: 100%;
}


</style>

这是我的应用程序文件，其中包含主路由器

<template>
  <div id="app">
  

    <router-view id="router"/>
  </div>
</template>

<style lang="scss" scoped>
@import '../sass/main.scss';

#app {
  font-family: Avenir, Helvetica, Arial, sans-serif;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
  text-align: center;
  color: #2c3e50;
height: 100%
  
}
#router{
  z-index: 0;
  width: 100%;
  height: 100%;
}

#nav {
  padding: 30px;
}

#app div{
  width: 100%;
}


#nav a {
  font-weight: bold;
  color: #2c3e50;
}

#nav a.router-link-exact-active {
  color: #42b983;
}
</style>

Answer 1

尝试在 Viewport Height (vh) 中设置高度。该单位基于视口的高度。 1vh 的值等于视口高度的 1%：

#app {
  font-family: Avenir, Helvetica, Arial, sans-serif;
  text-align: center;
  color: #2c3e50;
  height: 100vh;
}

vue 应用程序不会在媒体查询中增长到 100% 高度

vue app will not grow to 100% height on media query
