jquery - 添加“返回顶部按钮”

问题描述

我在 Shopify 做一个项目，基本上是做一个卖手表的网站。实际上，我在这里和那里很容易解决了几个问题，但我遇到的问题是当我必须在多个地方添加一些代码时。在我的 theme.liquid 中，我加载了我的 .css 和 .js 文件，这样我就可以轻松地在这两个文件中做一些事情，并且“魔法”发生在我的网站上。问题是，例如，如果我想添加一个返回顶部按钮，我知道我需要在我的 .js 文件中编写的函数，但我不知道在哪里放置我需要的 HTML 和 CSS 部分我的 theme.liquid 文件。据我所知，在这种特定情况下，我需要直接在我的主文件中编写 CSS 和 HTML 位，同时在我的 .js 文件中定义实际函数。

我知道浏览该代码有点烦人，但是任何人都可以帮助我解释我需要将 CSS 和 HTML 部分放在哪里，以便我的按钮确实出现在我的网站上吗？
