Hello! Was given a very helpful answer for a question yesterday, now I have another! 😬

I am looking to make these banner(?) or background images below links to a blog page and categories if at all possible? I've tried a few different drag and drop options but can't quite get what I'm looking for. Pretty much as it is now, text adapting to mobile, would be ideal. I tried buttons, but then they were different sizes etc. Plus I liked the tidiness of its current look.

Note: Password should be test123 (if it saved correctly).

Thanks in advance!
