如何在每个部分的底部中心放置一个箭头？

Question

我正在寻找我的＆＃34; FINAL WEBPAGE＆＃34;代码在主页中有两个部分。当用户点击同一页面上第一部分的箭头时，它会将它们带到第2部分。从第二部分开始，我将有一个箭头，如果用户点击它，它会将它们带回第一部分。我已经建立了箭头链接系统。但是，我看不到页面上的箭头？

如何让箭头<a href="#section two"> <i class="fa fa-angle-down" style="font-size:100px;"></i></a>位于第一部分的底部中心？

如何让箭头<a href="#section two"> <i class="fa fa-angle-up" style="font-size:100px;"></i></a>位于第二部分的底部中心？
