T4, 16.css can not save edits

infoparigi-gmail-com

I need to edit the 16.css file (in media/t4/css/16.css:947) to modify the aspect of the button.

I write:
.btn.btn-secondary {
background-color: #f6f6f6;
border-color: #dddddd;
color: #936432;
margin-bottom: 5px;
and I save.

All ok, in frontend I see the new aspect, but since a cache clean the file 16.css come back, without changes.
Same thing with 16-sub.css

I use purity IV 1.2.0 on joomla 5.0.1

How can I edit these files?

Hi infoparigi-gmail-com,
At the moment, the template using Bootstrap, you can not change the CSS file from the media/t4/css folder.
if you want to custom CSS for the template, you can create the custom.css file in the template/your-template/css folder.
