为什么我的cpanel或网站不使用我刚刚添加的新CSS文件？

Question

因此，该公司希望我编辑其index.html页面。我进入了cpanel，注释了不再需要的html，并添加了一些新的html。 （我认为我会这样做，而不是删除文件并添加一个新文件，因为我所做的更改很少）但是我确实添加了一个新的CSS文件来替换另一个文件。这个文件的名称当然只是一堆新的CSS。无论如何，我添加了新内容，但看起来却不尽如人意。这是截至https://gilbertmovingandstorage.com/的站点，这就是每个部分应该看起来像https://imgur.com/a/6zXObsX的样子。使用我的devtools并转到源代码，我查看了CSS文件（css / template-style.css），它仍然具有原始文件吗？即使我删除了它并用新版本替换了它？

p.s摘录中的css是我的cpanel上的css thats，应该链接到索引。 html文件。
