html - Safari 选择/下拉选项未与输入标签对齐

Question

这是我的下拉列表。在 Safari 中，下拉内容与可点击选择的边缘不对齐。包含选项的框的左右两侧应与 select 的左右两侧对齐。 Safari 是唯一发生这种情况的浏览器。

这是 safari 浏览器中下拉菜单和选项的样子

现在，下拉选项和下拉菜单没有对齐，看起来像

但我希望它们对齐/齐平，看起来像

这是创建下拉菜单的当前代码

select {
    padding: .375rem .75rem;
    background-color: #fff;
    width: 50%;
    border-radius: 1rem!important;

我的尝试:我将选择包裹在一个带有圆形边框的容器中，并将嵌套的选择移到右侧。然后我调整了 select 的左填充，使第一个选项与您的示例中的对齐

我还使用 @supports 将这种新样式应用于仅支持 webkit 的浏览器。

 .select-wrapper {      
   position: relative;
   border: 1px currentColor solid;      
   border-radius: 1rem;
   width: 50%;
   overflow-x: hidden;
   cursor: pointer;
   box-shadow: rgba(0, 0, 0, 0.04) 0px 1px 0px 1px;
}

.select-wrapper select {
   border: 0;
   cursor: pointer;
   -webkit-appearance: none;
   appearance: none;
   width: 100%;
   box-sizing: border-box;
}

.select-wrapper select:active, 
.select-wrapper select:focus {
   outline: none;
}

/* Webkit only style */

@supports (-webkit-font-smoothing: auto) {

 .select-wrapper::after {
   content: "";
   position: absolute;
   z-index: 1;
   top: calc(50% - 5px);
