I used a tab story map on AGOL. Now I realize I need to customize to fit into our agency web page. I downloaded the app from https://github.com/Esri/map-series-storytelling-template-js. Under the instructions it sates to go to app/config.js and located the LAYOUT property to edit the following lines with the desired colors.
// Group of matching theme across layout
// Header background
I do that changing the color to header: "#0053A4" from #6393BC, however the results are not changed. I did check to see that I am under id: ”tab” area.
The other problem I have is that a box for description appears for each of two tabs that have layers, but no content. I read where if you don’t fill anything in, it will not appear. However, I did not fill anything in and it appears.
