I changed the name of my trust levels, but it changed the order shown on the badges page, for example, trust level 1 is being displayed after trust level 2, is there a way to change that?
Because of how the badge page layout is currently built (flexbox), you might also need to adjust some margins at different screen widths if you change the order.
The need to fuss with the margins will go away later this year once we drop IE11 support (because we can then build the layout with grid instead of flexbox).
You can add custom CSS under admin > customize > themes, the easiest way to find the relevant CSS classes is to right click an element on the page you want to edit and inspect it in your browser.
