modify latest post.

Hello. I am really struggling now.

When you go to my site,
on the blog, on right side bar, on the latest post part,
you can find the padding-left.

But when I see the latest post part on the post,
there is no padding'left.

How this can be different?
I made this in the elements and apply to all pages.

Plz I want to remove the left padding on the latest post.
it is only showing on the blog page.
On the post page, the padding is gone.
