我是Jquery的初学者。我正在尝试使用其中的选择选项制作提交表单。但是,我发现下拉选项不在正确的位置。它们位于它们应该位于的地方的上方和左侧。Picture of Problem

我想要那些选择。在#34;正下方选择"对象

这是我的代码:



body {
  background: #333;
}
select,
option {
  background: rgba(255, 255, 255, 0.4) no-repeat scroll 16px 16px;
  width: 276px;
  height: 48px;
  font-family: 'Source Sans Pro', sans-serif;
  font-size: 18px;
  color: #fff;
  padding-left: 45px;
  padding-top: 12px;
  margin-bottom: 20px;
  overflow: hidden;
  -moz-border-radius: 4px;
  -webkit-border-radius: 4px;
  border-radius: 4px;
  -moz-background-clip: padding;
  -webkit-background-clip: padding-box;
  background-clip: padding-box;
}

<body id="gradient" style="height:90vh">

是否可以将这些选项文本放在框中?我很困惑如何控制下拉框的可能性。

form {
margin-left:auto;
margin-right:auto;
margin-top:80px;
width: 45vw;
height: 70vh;
padding:30px;
border: 1px solid rgba(0,0,0,.2);
-moz-border-radius: 5px;
-webkit-border-radius: 5px;
border-radius: 5px;
-moz-background-clip: padding;
-webkit-background-clip: padding-box;
background-clip: padding-box;
background: rgba(0, 0, 0, 0.4); 
-moz-box-shadow: 0 0 13px 3px rgba(0,0,0,.5);
-webkit-box-shadow: 0 0 13px 3px rgba(0,0,0,.5);
box-shadow: 0 0 13px 3px rgba(0,0,0,.5);
overflow: hidden; 
}
