Question

我目前正在创建单页面应用程序。在它上面我需要一切都始终在屏幕上。

但是当显示这些卡片时，它们的顶部会离开屏幕并且不会出现。如果我将高度100％关闭，这一切都会出现，但内容不再是屏幕上的中心......

html,

.leofullscreen {
    width: 100%;
    height: auto;
    bottom: 0px;
    top: 0px;
    left: 0;
    position: absolute;
}

.container {
    height: 100%;
    display: flex;
    justify-content: center;
    align-items: center;
}

.form-signin {
      width: 100%;
      max-width: 330px;
      padding: 15px;
      margin: 0 auto;
  }

#randomizingOptions {
    margin-top: 0.2rem;
    margin-bottom: 0.2rem;
}

Answer 1

您需要删除justify-content:center;规则，并最终为100vh设置height值为html, .leofullscreen，以避免将元素设置在中心但每边都溢出：（

如果满足您的要求，请参阅下面的示例。

html,

.leofullscreen {
    width: 100%;
    height: 100vh;
    bottom: 0px;
    top: 0px;
    left: 0;
    position: absolute;
}

.container {
    height: 100%;
    display: flex;
    align-items: center;/* this is also comming in the way !!!! */
}

.form-signin {
      width: 100%;
      max-width: 330px;
      padding: 15px;
      margin: 0 auto;
  }

#randomizingOptions {
    margin-top: 0.2rem;
    margin-bottom: 0.2rem;
}

如果您从0px移除底部：html, .leofullscreen，它也应该可以正常工作。

html,
.leofullscreen {
    width: 100%;
    height: auto;
    top: 0;
    left: 0;
    position: absolute;
}

.container {
    height: 100%;
    display: flex;
    justify-content: center;
    align-items: center;
}

.form-signin {
      width: 100%;
      max-width: 330px;
      padding: 15px;
      margin: 0 auto;
  }

#randomizingOptions {
    margin-top: 0.2rem;
    margin-bottom: 0.2rem;
}
