Reduce space between individual widgets in sidebar

Hi wayne. Each element in the sidebar can have an identifying id and/or class. You can use the browser Inspect tool to find the id and/or class names. If the names are unique then you can use them to adjust the margins/padding. If they don’t have unique names then you can use CSS pseudo-elements to target specific instances of an element, such as :last-child, :nth-of-type. Here’s a reference:
