子div在父div中的位置及其所引起的问题

问题描述 投票：0回答：2

我想将h1和按钮放置在底部底部：40％左侧：20％，即悬停在父div（id =“ head）的底部左下方。使用display：abolute;和定位标签使它们移到外面当屏幕尺寸改变时，屏幕是否存在。除了positiong方法还是没有使用flex或grid，还有其他方法吗，因为当我将显示更改为flex / grid时，我的另一个div受到影响。谢谢。

不确定，您最终想要的结果是什么。但这对我有效：

将父级设为绝对值，并相对于其父级设置showcase。如果您调整窗口大小，则尺寸/位置比率保持不变。

一种解决方案使用边距：

*{
  margin: 0;
  padding: 0;
}


body{
  background: #888;
  color: #fff;
  line-height: 1.5;
  font-family: 'Work Sans', sans-serif;
  overflow: hidden;
}

.button{
  font-size: 1.5rem;
  text-decoration: none;
  color: #fff;
  border: #fff 3px solid;
  padding: 1.3rem 2.3rem;
  border-radius: 10px;
  margin-top: 2.2rem;
  margin-left: 3rem;
  transition: all 0.6s ease;
}

.button:hover{
  font-size: 1.7rem;
  border: black 3px solid;
}


#head{
  position: relative;
  /* background-image: url(/images/snow-capped-mountains-under-the-cloudy-skies-1054289.jpg); */
  background-position: center;
  background-repeat: no-repeat;
  background-size: cover;
  height: 100vh;
  overflow: hidden;
}

#head .show-top {
  width: 90%;
  margin: auto;
  text-align: right;
  padding: 1.5rem;
  font-size: 1.2rem;
}


.show-top li{
  display: inline;
  padding: 0 1rem;
}

.show-top a{
  text-decoration: none;
  color: #333;
}


#head .showcase{
  margin-top: 20%;
  margin-left: 40%;
  transform: translate(-50%, -50%);

}

#head .showcase h1{
  font-weight: bold;
  font-size: 5rem;
  /* padding: 2rem; */
}
