I am hoping to use a custom css for my dash app and following one of CharmingData videos I tried downloading css file for one of the built-in themes and tweak it. But it is 62 pages long! I am far from being a CSS pro, so tweaking this is way out of my league.
Is there a minimalist css available - with just the basics:
It’s certainly possible to do this, but I’ve found it’s tricky to make a consistent design when cherry-picking. But it depends on how much you want to change. For smaller changes most components can be customized either by using the className and/or Style props or by targeting certain selectors in a custom stylesheet.
For more global theme changes, I think the Dash Mantine Components library is the easiest to use - see more here: Dash .
If you are using Bootstrap, you can create your own custom theme as well. More info here Sass · Bootstrap v5.3
Note that changes will only apply to the components of those libraries. If you are using dcc, or daq components, DataTable or Dash AG Grid, each of those components will need to have your custom theme applied if you want a pixel perfect design.
