Using Inspect, I found that div class “layer-content” provides padding around my post titles and post excerpts (see screenshot1.png). If I change the left/right padding in the browser inspector to 0px, the padding is removed (see screenshot 2.png). However, changing the padding in Appearance -> Customize -> Additional CSS does not do anything (see screenshot 3.png). What might be preventing my padding changes from working? I’m using the Sparkling theme, and my site is intechio.com.
Thanks.
