Hi - I have an extremely broad question regarding css that I was hoping someone may be able to assist me with. Almost 2 years ago I created a dashboard to view news article sentiment from the 2016 election. I recently loaded the dashboard (https://news-sentiment-analysis.herokuapp.com/) and realized that it is no longer rendering correctly. I believe that this is because the .css that I had created is no longer valid. The code for my app is here: https://github.com/cmclaughlin829/News_Sentiment_App and the .css I used is hosted here: https://codepen.io/cmclaughlin829/pen/pGwbvG.css
I originally developed this using the dashUI library hosted here https://github.com/rmarren1/dash-ui. It appears to not have been updated in sometime and the .css that I copied from there also shows ‘Pen Not Found’ when loading (https://codepen.io/rmarren1/pen/mLqGRg.css). I am very unfamiliar with css but am hoping there is something simple that can be fixed here. Any ideas?
