位置固定的css在角度材料中添加身体标签

Question

如果我在某些固定的情况下使用position: fixed; width: 100%; top: 0px; for md-select md-autocomplete，我会遇到一些问题。对于几乎所有md-select 选项，我都面临着角度材料的这个问题。 它将CSS 属性动态添加到正文部分。

position: fixed; width: 100%; top: 0px; 和 scrollY。

index.html

<header class="container-fluid" id='headerControl' ng-cloak ng-controller = 'headerControl as ctrl'>
  <div layout="row">
    <div class="col-md-2 col-sm-2 logo">
      <a href="/">
        <img src="img/scooby.svg" alt="Logo" width="120px" class="img-responsive"></a>
    </div>

    <div class="col-md-7 col-sm-6 search-head hidden-xs">

        md-search-text="ctrl.searchText"

        md-items="item in ctrl.querySearch(ctrl.searchText)"

Answer 1

您是否在浏览器中检查过它？您可能会看到 md 样式覆盖它。向它添加一个类并覆盖样式，如果需要，则使用重要

.md-select.fixedTop{
    top: 0px !important;
}

Answer 2

我想你检查一下 .md-select.fixedTop{ top: 0px !important; }
