包简介

Magento 2 module which loads additional critical CSS files per specific layout handles

README 文档

README

The Collab_AdditionalCriticals module is a simple module that differentiates critical styles used across different areas of Your Magento app.

Configuration

Module does not have any configuration options. You just need to fulfill the requirements specified in prerequisites.

Pre-requisites

dev/css/use_css_critical_path must be set to 1 in core_config_data or in config.php/etc.php
category.css, simple-product.css and configarble-product.css along with critical.css must be present in app/design/frontend/<Vendor>/<Theme>/web/css/ directory. Those need to be generated by You or Your team using custom grunt tasks for example, this module does not provide any of those files.

How it works?

At specific layout handles module removes default critical CSS block filled with contents of critical.css file and creates new block with contents taken from previously prepared files.

Layout Handle	Loaded File	Comment
`catalog_category_view`	`category.css`	`category.css` should be generated against real category page on Magento app with `dev/css/use_css_critical_path` set to 0
`catalog_product_view_type_simple`	`simple-product.css`	`simple-product.css` should be generated against real simple product page on Magento app with `dev/css/use_css_critical_path` set to 0
`catalog_product_view_type_configurable`	`configurable-product.css`	`configurable-product.css` should be generated against real configurable product page on Magento app with `dev/css/use_css_critical_path` set to 0
`default`	`critical.css`	`critical.css` should be generated against CMS page on real Magento app with `dev/css/use_css_critical_path` set to 0

Why choose this extension over other solutions?

We don't believe in efficient modules which have tons of options - simple as that - modules which have multiple options, are prepared for many integrations always have some performance footprint for application. Having this in mind we are trying to provide simple, portable and independent modules which sometimes require some basic Magento 2 development skills.
