how to make one big css and one big js file?

-- HikaShop version -- : 3.0.1
-- Joomla version -- : 3.6.5

Hi,
1. I want to make one big css file (custom.css) from 3 css files to make one request:
1. custom.css (my template)
2. hikashop.css?v=301
3. notify-metro.css

At first I have placed all code from (2) and (3) into custom.css (1).
I have tried to change css links in "adm/components/com_hikashop/helpers/helper.php" to my template, but it breakes a back end hikashop css.
Then I saved as "none" front end css and styles for the front end css files in configuration > css options. But the hikashop.css?v=301 file is still downloaded.
The same with notify-metro.css

2. Can I place notify.min.js code into hikashop.js?v=301 to make one request?

Where have I to add the changes?

Thanks

Hi,

You need to use Joomla dedicated plugin to do so, like JCHoptimize

Regards,

Sorry, can you read, please, one more time my question (the whole text)?

To make one css file (from 3 files) and to make one js file (from 2 files) I think I need no extra plugin.
I saved as "none" front end css and styles for the front end css files in configuration > css options. But the hikashop.css?v=301 file is still downloaded. Before Hikashop 3 I had this problem not.

I just asked:
how to stop download hikashop.css?v=301 (where can I change the link?)

Hi,

That hikashop.css file is always added. There is no setting to not add it.
We do that as it contains crutial CSS for the display of the layouts of HikaShop's frontend.
It's like hikashop.js

If you don't want to load these files, it's going to be complex. You'll have to edit the core files of HikaShop.
For example for the hikashop.css, you would have to edit the file administrator/components/com_hikashop/helpers/helper.php and remove:
$doc->addStyleSheet(HIKASHOP_CSS.'hikashop.css?v='.HIKASHOP_RESSOURCE_VERSION);
