标签： html css

以下是有关此页面第1部分的网页量的示例。My webpage example.

如何将"fa fa-angle-down"置于页面的底部中心？

我如何将以下内容集中在一起？

<div class="profile box">
         <div class="shape"></div>
         <div class="shape2">

最后，我如何将我的文字放在导航栏上？

<h1 class="nav-title">Liam Docherty's Digital Portfolio</h1>

就shape和shape2而言，我如何才能将它们放在背景图片hero的中间位置？

您好我解决了您的问题，您可以查看以下代码。 我改变你的代码，你可以检查这个。 .nav-title更改和上面的形状div添加form-group div 

 Streams.zip(listA, listB, Pair::of)
.findFirst(pair-> pair.getFirst() < pair.getSecond());
