Can't get identical featured image size in divi post list

Hi there,

Title says it all. I am trying to have a vertical post list that shows feature images with identical sizes. So far:

• I have ensured the thumbnail size was defined
• I recroped some of the pictures to test if it would help: same size pictures come out differently
• I tried to have a custom CSS (did not seem to have any effect)
  .et_pb_post .entry-featured-image-url {
  float: left;
  width: 100%;
  max-width: 150px; /* Taille maximale de l'image */
  height: auto; /* Maintient le ratio de l'image */
  margin: 0 20px 30px 0;
  }
  .et_pb_post .entry-featured-image-url img {
  width: 100%; /* L'image remplit le conteneur */
  height: 100%; /* Force la hauteur pour un format homogène */
  object-fit: cover; /* Couvrir tout le conteneur sans déformer l'image */
  }

Nothing worked. Even though not exactly the case, it looks like alignment is one out of 2.

Spent hours on this and lost my hair. I am lost.

Any idea anyone?

Best regards

 

So it looks like the size of the featured picture is a function of the length of the excerpt
