Instant Apps Custom CSS

[Tiff]

Hello! I am looking for support on learning custom CSS options for the Nearby Instant App.

These are some customizations we would like to have in our app. Would it be possible to:

1) Change the font size and bold text in some areas i.e., "Clear search location"

2) Change the background (secondary) color behind just the "Filter" button. We want to make this more apparent and easy to see.

3) Change the text in the filter widget to "Close Filter".

Any suggestions or help appreciated. I have only used custom CSS where Esri staff or others on this forum have suggested, so limited knowledge on this.

@KellyHutchins we would like to change the color of this element to white, are you able to send the CSS in order to do so? 

Thanks!

Looks like sidebar correct? Yes but the image above looks white to me (could be my monitor). I'm trying to determine if its the panel that is a different color or if its background to the content in the panel? Here's a sample app where i've modified the colors for both of those sections using obnoxious colors to make it easy to determine which you want to modify:

Once you determine the color to change you can use the value #fff to set the color to white.

background-color:magenta;

#details-panel{
--calcite-panel-background-color:yellow;
