Sydney is a pretty excellent theme and we love it very much!
I use a child theme to display more then 3 posts according to the link https://forums.athemes.com/t/latest-news/2365/2. I also display the posts only with feature image and title (according to the link https://forums.athemes.com/t/hide-posts-excerpt-from-latest-news-widget-only/11428/2).
But sometimes those blog-posts may not align like a regular table. Our feature images are the same size. It seems that the title lines of different post may different, such as two titles with 2 lines and other title with 1 line. Please see the following picture.
How could I set each row of blog-posts with the same number posts, thanks.
