How to add space/gap between sidebar and content/posts?

Sydney is an awesome theme, I just love it !
I am having a problem whose solution i can’t find. Its frustrating me from hours.
I don’t want the side bar widgets and posts be attached.
i want a different box for each post and widget.

How I Want it to be :
I just want the sections divided in different sections rather than all in one :slight_smile:
Thank You so Much :slight_smile:

Hello there,

Put off your previous styling and replace it with this one:

#secondary .widget {
  background-color: #ffffff;
  padding: 15px !important;
  margin-bottom: 15px; 
  border-radius: 10px;
  background-color: #fff;


Wow thank you for the quick reply!
Where and what to replace?
I am A beginner and don’t know much.
Btw I applied the css in the additional css from customize but the widgets and posts didn’t separate.
I want it like the pic:
Thank you.
