Ionic thumbnail issue

Here is my list.

You can see the space below my contents and the thumbnail. I think this is because the thumbnail is square originally although I set the max height less that the width.

.article-thumbnail {
  max-height: 52px !important;

I’m wondering how to remove the space? Or is there a way to change the width of the thumbnail? Thanks

I found a solution but not by using item-thumbnail-left.
