You can customize the sidenav width by downloading our source files
We have two variables ($sidenav-width & $sidenav-large-width) in this file : https://github.com/axentix/axentix/blob/master/src/scss/utilities/_variables.scss
You can also use your custom css but with this method you have to change padding / margin values if you use our layouts.
There is no alternative using the sources files.
But if you to use the npm method you can run
npm update when you want to update the framework.
Using the CDN method, you just have to change the version number to the actual version inside the CDN link.
Because we make some bugfixes and changes on each versions, we don't force users to always update Axentix.
Is there a class to make it looks like more darker or something?
neu-darken will make your component darken.
