magento.stackexchange https://magento.stackexchange.com/questions/285028

Question

i'm trying to remove some unnecessarily css and javascript that is included in the homepage. For example, the swatches.mini.css, blog-m.min.css, blog-custom.min.css, calendar.min.css doesn't seem to need to be loaded at homepage, etc. I would like to try to remove them in order to increase the pagespeed.

Solution

Create cms_index_index.xml at your theme layout folder.

Add remove code:

<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
    <head>
        <remove src="Magefan_Blog::css/blog-m.css"/>
        <remove src="Magefan_Blog::css/blog-custom.css"/>
        <remove src="Magefan_Blog::css/blog-m.css"/>
        <remove src="Magento_Swatches::css/swatches.css"/>      
    </head>
</page>
