How can I add a sign-up link to the bottom of my blog page, below the blog thumbnail images? I already have the code prepared but am not sure how to inject it into the page. Any help is appreciated.

Site URL: https://www.octantacademics.com/homepage-draft-iii

Without changing the padding for the rest of the webpage, I would like to make the top/bottom padding for the 'Our Approach' section (URL provided) consistent with that of the 'Who We Are' and 'Newsletter' sections. The latter two sections have background images that are simply the colors you see. I am assuming the solution will require a CSS code injection for this specific page section, but I do not know what code to use. Any help is appreciated!
