One site two blogs - how to code individual customisation for each

Hello - 

I am building out a new blog section on this site

https://www.straightupbookkeeping.com.au/short-courses/

And want to edit the spacing on just this blog single posts without effecting the code of the other blog. Is this possible to target one? 

I am hoping to reduce the padding at the top of the individual posts using 

/* Blog Individual: top space reduce */
.blog-item-wrapper article.entry {
    padding-top: 80px;
}

@tuanphan thanks for the help! 

Is there also a way to target just this blog for further cutomisation... 

At present I want to change the "Read More" text on just one blog (without it affecting the other) and also have the headings centre align on the individual blog pages.
