编辑模板
您可以编辑模板以自定义在线商店的内容、布局、版式和颜色。每个模板都提供了一些分区和设置，可供您用于更改商店的外观，而无需编辑任何代码。
自定义模板前的准备工作
在自定义模板之前，最好执行以下任务：
复制您的模板以创建一个备份副本。这使您在需要时能够轻松地放弃更改并重新开始进行自定义。
确保您了解可用的支持级别。
了解上传图片的要求和最佳做法。
模板编辑器
模板编辑器会在树形图中显示您当前在侧边栏中查看的模板的所有内容。您可以使用展开图标 ▸ 来展开分区结点以查看其中的块，还可以使用折叠图标 ▾ 将其折叠来隐藏块。您可以点击任何分区或块来查看其设置。
侧边栏模式
模板编辑器提供两种模式来利用屏幕上的所有空间。
双侧边栏模式适合较宽的浏览器窗口和较大的屏幕，而单侧边栏模式适合较窄的浏览器窗口和较小的屏幕。侧边栏模式决定了设置面板在编辑器中的显示位置。
双侧边栏模式
如果您的屏幕宽度大于 1600 像素并且浏览器窗口已完全展开，或者您的浏览器窗口已扩展到至少 1600 像素宽度，此时将显示两个侧边栏。左侧的侧边栏包含导航面板，右侧的侧边栏包含设置面板。
单侧边栏模式
较窄的浏览器窗口仅显示一个侧边栏来为模板预览留出空间。点击分区或块以对其进行编辑时，设置面板会在侧边栏中的导航面板顶部打开。

Editing your theme
You can edit your theme to customize your online store's content, layout, typography, and colors. Each theme provides sections and settings that allow you to change the look and feel of your store without editing any code.
Before you customize your theme
Before you customize your theme, it's a good idea to do the following tasks:
Duplicate your theme to create a backup copy. This makes it easy to discard your changes and start again if you need to.
Make sure that you understand what level of support is available.
Learn about the requirements and best practices for uploading images.
Theme editor
The theme editor displays a tree view of all the content for the template that you're currently viewing in the sidebar. Expand a section node using the expand icon
▸to view its blocks, or collapse it using the collapse icon▾to hide the blocks. You can click on any section or block to view its settings.Sidebar modes
The theme editor offers two modes to make use of all of the space on your screen.
Doule sidebar mode is for wider browser windows and larger screens, and single sidebar mode is for narrower browser windows and smaller screens. The sidebar mode determines where the setting panel appears in the editor.
Double sidebar mode
If you have a screen larger than 1600 pixels wide and your browser window is fully expanded, or your browser window is expanded to at least 1600 pixels wide, then you'll have two sidebars. The left-hand sidebar contains the navigation panel, and the right-hand sidebar contains the setting panel.
Single sidebar mode
Narrower browsers only have one sidebar to conserve space for the theme preview. When you click on a section or block to edit it, the setting panel opens over top of your navigation panel in the sidebar.
