All these issues go away with bulma.
No tool to customise theme is great. I don't want a bootstrap looking theme. It gets in the way... bootstrap is structure and styling throwing in the kitchen sink and half the house but not adding any doors or windows and you can't hide a builder to add more without it costing a kidney.
Then don't use the JS parts of BS?

These sentences are contradictory. The tool allows you to make a theme that doesn't look like everyone else's. Bulma does not have this option. You will end up with a "Bulma-looking" theme.
>It gets in the way
Unlike Bulma's visual styling? If you don't want a default-looking theme, wouldn't you need to customize it then? Doesn't lacking any tools to do so make this harder? I don't understand this argument.
Same with foundation and semantic UI. Bulma and other small libraries are much more flexible in this regard.
I can take the BS source, comment out half of it and end up with Bulma. If I started with Bulma, I'd have to write lots of code to end up with a framework that rivals BS.
