This is lovely! I mean... LOVELY!
Really glad you approve with such gusto! Please do send us any feedback or thoughts you have as it's still an early version and we're keen to build more tools
I had hard time explaining the lack of old school baseline to some of my colleagues. Maybe add a little education that we're designers for the web, thus we use the web rules.
In Define Sizes, maybe add other values, the same way as you've done with the fonts. I normally do H scales of 1.1681 for desktop and 1.33 for mobile... not sure what I'm trying to say, but more helpful sizes will help designers with the choice.
But I fucking love the Sketch/CSS export...
Fantastic, thank you so much for your input. Adding pre-defined scaling options (such as the Golden Ratio you favour) was actually an idea we thought might be useful and we hadn't considered the experience of a print-based mental model person coming to it so that was great insight. If you have any other suggestions or questions when using it I'd be very keen to hear them, Thanks again
Great to know you find our little tool useful Antonio, thank you very much. Please do send us any thoughts or suggestions you have on it, we're very keen to get as much feedback as possible
