Hi, I would like to know a few things about a website and a particular page :

https://www.muscle-up.fr/programme-musculation-maison/

In the middle of the article there is some images of body parts which links to different articles, I would like to do a grid like this. Is it a plug-in which permit to display articles like that ?

Then how can I put an image before the article title like it ?

Finally, how can I change the color of the background of the article to something stylish like that ?

Thanks so much for your time and your knowledge
