如果您的计算机上的 ZIP 文件中有一个模板，您可以将它上传到后台的模板页面。
上传之前，请确保将模板文件压缩为单个 ZIP 文件。

PC：
在模板库部分中，点击上传模板。
在上传模板窗口中，点击选择文件以选择要上传的 ZIP 文件。
点击上传。模板将添加到后台的模板页面。

安卓系统：

轻触管理模板。
在模板库部分中，点击上传模板。
在上传模板窗口中，点击选择文件以选择要上传的 ZIP 文件。

切换模板
将新模板添加到商店中后，它们显示在 Shopify 模板页面的模板库中。您可以通过将模板发布到您的在线商店来切换新的模板。发布新模板时，旧模板仍会显示在模板库中（如有需要，您可以换回旧模板）。
如果您手动更新模板，更新后的模板版本将在模板库中显示为单独的版本。切换到更新后的版本时，旧版本的模板仍会显示在模板库中。要了解详细信息，请参阅更新模板。
准备切换模板
将模板添加到模板库时，您可以在发布模板之前对其进行自定义。在替换现有模板之前，您可获得一个很好的机会查看新模板并调整设置和内容，以反映您的业务。您还可以在准备好的多个模板之间切换，无需再次进行设置。
切换到新模板时，不会更改或删除商店的产品、产品系列、导航菜单、页面、博客文章，因为这些功能均在后台进行管理，且独立于模板。但是，对于您上传的每个模板和模板版本来说都，使用模板编辑器、模板代码编辑器和语言编辑器进行管理的内容和设置均独一无二。
您在线商店的以下部分与该模板关联。您必须针对您想要使用的每个模板自定义在线商店的这些部分。
应用于商店中分区和块的设置
全局模板设置，包括应用于在线商店的颜色和字体
文本和措辞
代码自定义，包括应用添加的代码自定义
可用的模板样式
并非所有模板都支持全部 Shopify 功能。您应该查看模板的功能列表，以确保其具有您需要的功能。

Upload a theme file from your computer
If you have a theme in a ZIP file on your computer, you can upload it to the Themes page in the admin.
Before you upload, make sure that your theme files are compressed into a single ZIP file.
Steps:
PC：
From your Shopify admin, go to Online Store > Themes.
In the Theme library section, click Upload theme.
From the Upload theme window, click Choose File to select the ZIP file that you want to upload.
Click Upload. The theme will be added to the Themes page of your admin.
iPhone：
From the Shopify app, tap Store.
In the Sales channels section, tap Online Store.
Tap Manage themes.
In the Theme library section, click Upload theme.
From the Upload theme window, click Choose File to select the ZIP file that you want to upload.
Click Upload. The theme will be added to the Themes page of your admin.
Android：
From the Shopify app, tap Store.
In the Sales channels section, tap Online Store.
Tap Manage themes.
In the Theme library section, click Upload theme.
From the Upload theme window, click Choose File to select the ZIP file that you want to upload.
Click Upload. The theme will be added to the Themes page of your admin.
Switching themes
When you add new themes to your store, they appear in the Theme library section of the Themes page in Shopify. You can switch to a new theme by publishing it to your online store. When you publish a new theme, your old theme is still available in the theme library (and you can switch back to it if you want).
If you update your theme manually, then the updated version of your theme appears as a separate version in the theme library. When you switch to the updated version, the old version of your theme is still available in the theme library. To learn more, refer to Updating themes.
Preparing to switch themes
When you add a theme to your theme library, you can customize it before you publish it. This is a good opportunity to review the new theme, and adjust the settings and content to reflect your business, before you replace your existing theme. You can also switch between multiple themes that you've prepared without needing to set them up again.
Your store's products, collections, navigation menus, pages, blog posts aren't changed or deleted when you switch to a new theme, because they're managed in the Admin, separate from the theme. However, the content and settings that are managed using the theme editor, theme code editor, and language editor are unique to each theme and theme version that you upload.
The following parts of your online store are associated with the theme. You must customize these parts of your online store for each theme you want to use.
The settings applied to sections and blocks in your store
Global theme settings, including colors and fonts applied to your online store
Text and wording
Code customizations, including code customizations added by an app
Available theme templates
Not all themes support all Shopify features. You should review the theme's feature list to make sure that it has the features you need.
