我是Angular / Bootstrap的新手,目前正在尝试将图像放在左上角导航栏的顶部。使用填充/边距可以解决正常分辨率/静态屏幕尺寸的问题,更改尺寸可以将图像放置在其他位置。
我曾尝试使用padding和margin,但是正如我所说,在更改浏览器尺寸时,无法使其在左上角“发粘”。 同样使用引导类,例如“ pull-right”(仅适用于测试用例)不起作用。
我当前的代码如下:
<header>
<div class="cloud">
<!-- Navigation -->
<nav class="navbar navbar-expand-lg navbar-dark $green static-top">
<div class="container">
<a class="navbar-brand" href="#">
<img src="https://cdn.sstatic.net/Sites/stackoverflow/company/img/logos/so/so-logo.svg?v=a010291124bf" class="pull-right" alt="" width="431.27" height="55.35">
</a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarResponsive"
aria-controls="navbarResponsive" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarResponsive">
<ul class="navbar-nav ml-auto">
<li class="nav-item active">
<a class="nav-link" href="#">Home
<span class="sr-only">(current)</span>
</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">About</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Profile</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Impressum</a>
</li>
</ul>
</div>
</div>
</nav>
</div>
<div class="first">
<h1>TestSite</h1>
</div>
</header>
我希望左上角有一张图片,它会在更改浏览器大小/设备时响应地停留在该图片上
答案 0 :(得分:0)
请检查此代码以查看这是否是所需的结果。可以正常使用的演示程序here
对代码进行的主要更改是
。bg-dark
,并在导航中删除了$green static-top
。 <nav class="navbar navbar-expand-lg navbar-dark bg-dark">
width
标记中删除了height
和img
属性。
.navbar-brand img{
width: 50%;
}
<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" rel="stylesheet"/>
