Hi @Libor Danek
Are you wanting to adjust the individual widths of the lists? If you're using Chrome, there are Chrome Extensions for using with Trello which extend the functionality quite a bit.
The one that I use is Pro4Trello, which can be found here https://chrome.google.com/webstore/detail/pro-for-trello-free-trell/hcjkfaengbcfeckhjgjdldmhjpoglecc
I use it to adjust the widths of my lists as well as change the background colours, which is AMAZING!
If you want the list of colours that Pro4Trello will accept - here is a list https://www.w3schools.com/cssreF/css_colors.asp
This is what mine looks like (without the list widths changed)
I've been using this Chrome Extension for ages, but if you remove the extension all the tweaks you've done will disappear and you won't see any difference on the mobile or native apps, only if you're using Chrome on a desktop (Windows or Mac).
Hope that helps
