Can I apply this Post Grid plugin to a 'tagged' blog page? Which only has selected blog posts on it, ones that have a certain tag in it, e.g. https://maaree.com/tag/blog/
The problem is is that it's not a manually built page, but it has been created automatically by editing the URL. I can't physically edit the single page. I think it will need to be done through using CSS code.
Any help appreciated.
