change blog post text formatting in wells

Site URL: https://www.joequint.com/blog

Hi - I'd like to change the font color, size, line spacing, etc. on both the main blog page (https://www.joequint.com/blog) as well as the posts themselves (https://www.joequint.com/blog/luis).

Also, is it possible to add spacers/right padding to the excerpt on the main blog page (https://www.joequint.com/blog) so the text doesn't run full-width?

Thanks!!

Hi.

Q1. For title, description, date...or?

Q2. Add to Design > Custom CSS

/* blog excerpt */
.collection-type-blog article .entry-content {
    padding-left: 5vw;
    padding-right: 5vw;
}
