How do I add padding to top of Blog page in version 7.1?

On a blog page, I added a section above the blog-page content. And now the section with all the blog post has VERY little padding/top spacing compared to how all sections looks across this side. I cant/not possible to add blocks within the blog-section, I guess I need code to manually set the padding for this section? How?

Hi @peterbjerg,

I had the same question, and truanphan helped me with this bit of CCS:

Add to Home > Design > Custom CSS

.blog-item-wrapper {
    padding-top: 10vh;
}
