按下按钮时制作全高和全宽的菜单栏

Question

我想当我按下右上角的菜单按钮时，一些东西从左滑到右全屏（全高和全宽），其他一切都消失了。这里的问题是，如果您向下滚动然后单击菜单按钮，它不会显示它只显示在顶部。另外还有一些我不太明白的东西，高度和宽度。如果我想要覆盖整个页面或只覆盖我们可见的高度和宽度，我们该怎么做？为此，我将 100% 的高度和宽度设置为页面的可见部分，如果我们希望整个页面都被某些东西覆盖怎么办？高度和宽度如何工作？

$("#side-button").click(function(){
  if ($("#side-bar").css("display") == "block"){
    $("body").css("overflow","auto");
    $("#side-bar").animate({width: "0%"},400,function(){
        $("#side-bar").css("display","none");
    });
  }
  else{
    $("#side-bar").css("display","block").animate({width: "100%"},400,function(){
      $("body").css("overflow","hidden");
    });
  }
});

html{
  height:100%;
  width:100%;
}
body{
  position: relative;
  height:100%;
  width:100%;
}

#side-bar{
  position: absolute;
  width:0%;
  background: black;
  height: 100%;
  z-index: 100;
  display:none;
}

#side-button{
  display:flex;
  position:fixed;
  right:10px;
  top:10px;
  z-index: 100;
  width:30px;
  height:30px;
  justify-content: space-around;
  flex-direction: column;
}

#side-button div{
  width:100%;
  height:4px;
  background-color: gray;
  display:block;
}

#side-button:hover #first{
  transform: rotate(1turn);
  transition: 1s transform;
}

Answer 1

侧边栏有绝对位置，仍然引用文档。

所以您想 #side-bar 通过将其放置在文档流之外 fixed。
然后它将是 "above" 视口。

我会使用顶部、左侧、底部和宽度来设置动画。

$("#side-button").click(function(){
  if ($("#side-bar").css("display") == "block"){
    $("body").css("overflow","auto");
    $("#side-bar").animate({left: "-100%"},400,function(){
        $("#side-bar").css("display","none");
    });
  }
  else{
    $("#side-bar").css("display","block").animate({left: "0%"},400,function(){
      $("body").css("overflow","hidden");
    });
  }
});

html{
  height:100%;
  width:100%;
}
body{
  position: relative;
  height:100%;
  width:100%;
}

#side-bar{
  position: fixed;
  top:0;
  bottom: 0;
  left:-100%;
  width: 100%;
  background: black;
  z-index: 100;
  display:none;
}

#side-button{
  display:flex;
  position:fixed;
  right:10px;
  top:10px;
  z-index: 100;
  width:30px;
  height:30px;
  justify-content: space-around;
  flex-direction: column;
}

#side-button div{
  width:100%;
  height:4px;
  background-color: gray;
  display:block;
}

#side-button:hover #first{
  transform: rotate(1turn);
  transition: 1s transform;
}

你可以将侧边栏的绝对位置改为固定位置，该位置将相对于视口并固定在顶部

$("#side-button").click(function(){
  if ($("#side-bar").css("display") == "block"){
    $("body").css("overflow","auto");
    $("#side-bar").animate({width: "0%"},400,function(){
        $("#side-bar").css("display","none");
    });
  }
  else{
    $("#side-bar").css("display","block").animate({width: "100%"},400,function(){
      $("body").css("overflow","hidden");
    });
  }
});

html{
  height:100%;
  width:100%;
}
body{
  position: relative;
  height:100%;
  width:100%;
}

#side-bar{
  position: fixed;
top: 0;
  width:0%;
  background: black;
  height: 100%;
  z-index: 100;
  display:none;
}

#side-button{
  display:flex;
  position:fixed;
  right:10px;
  top:10px;
  z-index: 100;
  width:30px;
  height:30px;
  justify-content: space-around;
  flex-direction: column;
}

#side-button div{
  width:100%;
  height:4px;
  background-color: gray;
  display:block;
}

#side-button:hover #first{
  transform: rotate(1turn);
  transition: 1s transform;
}
