How to make entire <article> in blog post page linked?

I am using a theme where on the blog page only the featured image and the post title are using anchor link. On clicking it redirects to that respective post page.

But I want to link the entire so that if anybody clicks on that area it will redirect to that respective post page.

I saw a website https://www.tidio.com/blog/ where their entire article section was linked. So when i inspect their code, I found that they are using pseudo-element ::before to make the whole section linked.

Similarly, I also tried the same but didn't work out for me. It really helps if someone can assist me in this. I am also attaching an image for better understanding.

Thanks in Advance.
