margin-bottom: 0px; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-kerning: auto; font-optical-sizing: auto; font-feature-settings: normal; font-variation-settings: normal;

line-height: normal; font-family: "Helvetica Neue"; white-space: normal;">default.xml</p><p class="p1" style="margin-top: 0px; margin-bottom: 0px; font-variant-numeric: normal; font-variant-east-asian: normal;

font-family: "Helvetica Neue"; white-space: normal;">default.xml 是 Magento 2 中默认使用的布局文件,用于指定页面的基本结构和组件。该文件通常保存在主题的 Magento_Theme/layout/ 目录中。下面是一个简单的 Magento 2 default.xml 文件的代码示例:</p><pre class="brush:as3;toolbar:false"><!-- File: app/design/frontend/MyVendor/mytheme/Magento_Theme/layout/default.xml --> <page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd"> <body> <referenceBlock name="header.container"> <block class="Magento\Theme\Block\Html\Header" name="header" as="header" before="-"> <arguments> <argument name="show_part" xsi:type="string">welcome</argument> </arguments> </block> </referenceBlock> <referenceContainer name="content"> <block class="Magento\Framework\View\Element\Template" name="page.main.title" template="Magento_Theme::html/title.phtml"/> <block class="Magento\Framework\View\Element\Template" name="page.messages" template="Magento_Theme::html/messages.phtml"/> <block class="Magento\Framework\View\Element\Template" name="page.main" template="Magento_Theme::html/container.phtml"/> </referenceContainer> <referenceBlock name="footer"> <arguments> <argument name="show_part" xsi:type="string">powered</argument> </arguments> </referenceBlock> </body> </page></pre><p class="p1" style="margin-top: 0px;
