I didn’t know how I was supposed to post the link. It appeared WP.org was blocking it.
On the upper section, notice how the brown doors do not take up the entire width of the image frame. In the lower section, I used the portfolio element, and it takes up the entire width.
Another twist that I just found out, when I zoom in to 125%, the doors appear as they should. Also, when I adjust the screen size and let the responsiveness of the website interact, the image frames only get so large, then they stop ‘responding’. All of the other elements continue to get larger, as the screen gets wider, but the image frames stop.
