Create a view directory in your module's directory. This directory will contain all of the templates and layouts for your module. For example, if your module is called Vendor_ModuleName, the view directory should be located at app/code/Vendor/ModuleName/view. Inside the view directory, create a frontend directory. This directory will contain all of the templates and layouts for the frontend of your website.Inside the frontend directory, create a layout directory. This directory will contain the layout files for your module. Inside the layout directory, create a new layout XML file. The name of this file should match the name of the layout handle that you want to override. For example, if you want to override the catalog_product_view layout handle, you would create a file called catalog_product_view.xml.In the layout XML file, you can use the <referenceBlock> and <referenceContainer> tags to override the templates and blocks for the layout handle. For example, if you want to override the product name template, you could use the following code:

    <action method="setTemplate">
        <argument name="template" xsi:type="string">Vendor_ModuleName::product/name.phtml</argument>
    </action>
</referenceBlock>

In the frontend directory, create a templates directory. This directory will contain the custom templates for your module.Inside the templates directory, create a new template file with the same name as the template specified in the layout XML file. In the example above, this would be a file called name.phtml.In the template file, you can add your custom HTML code. This code will be used to override the default template.Clear the cache and deploy the static content to see your changes.

To override an HTML file in Magento 2, follow these steps:

1. Create a custom theme (if you don't already have one). This can be done by creating a new directory under app/design/frontend/ and naming it according to your custom theme's name. For example, if your custom theme is named "MyTheme", the directory structure should be app/design/frontend/{{vendor}}/MyTheme.
2. In your custom theme directory, create a new directory named "Magento_Theme".
3. Inside the "Magento_Theme" directory, create another directory named "web".
4. Copy the HTML file that you want to override from the Magento base theme. You can find the base theme files under vendor/magento/theme-frontend-blank.
5. Paste the copied HTML file in the "web" directory of your custom theme. Ensure that the directory structure of the custom theme matches the original file path. For example, if you want to override vendor/magento/theme-frontend-blank/Magento_Theme/templates/html/header.phtml, the new file should be placed in app/design/frontend/{{vendor}}/MyTheme/Magento_Theme/web/templates/html/header.phtml.
6. Modify the HTML file in your custom theme as per your requirements.
7. Run the following command to deploy the static files of your custom theme: php bin/magento setup:static-content:deploy -f The -f flag is used to force the deployment without asking for confirmation.
8. If the website is in production mode, also run the following command to clear the generated static files: php bin/magento cache:clean

After following these steps, the HTML file from your custom theme will be used instead of the original file from the Magento base theme.
