Dont know if this works though, the Slider element is a little weird. Try using the Firefox/Chrome developer tools inspector to identify the element which you need to actually adress. You can also include a local CSS in your Dash app and then write your CSS there. It’s somewhere on the forum.
Yes… I agree with you… I wrapped into another div as you suggested, but I didn’t work again. Thank you very much! However, right now, my team are leaving Dash for a moment to develop the web app using raw plotly.js. I hope Dash will improve with time with proper documentation and more flexibility of the components, specially in terms of UI.
Hi, I know this is super late but just for begginners like me, there is a function ‘dash.html.Center()’, it makes miracles in this sense, you can use it with bootstrap, core or basic html components, basicly with everything I think!
