Changing the style of radio button inputs?

I would like to change the style of the radio button inputs on my page – for example, each answer is currently in a box with a grey background and no borders; the boxes are spaced apart from each other, and there’s little space between the radio button and the answer text. I want to change it so that it looks more visually similar to the checkbox fields on my Skuid page I currently have the following CSS on this field, to stretch out the radio buttons to the width of the panel. I tried editing other attributes of these items (background color, border) with no success (since I’m editing the background/border of the field editor itself, not the radio button components when I do this): .allLabel .nx-basicfieldeditor-item.allLabel .nx-basicfieldeditor-item-label { width: 1%; } .nx-basicfieldeditor-section-body > .nx-basicfieldeditor-item.allLabel > .nx-field { width: 99%; } I also tried editing the multiselect settings under my custom theme, but that also didn’t yield the desired results. Does anyone know what item I should be editing the CSS attributes of or where I can go to edit these settings? Thanks in advance!
