Intermittent 3rd column on 900px display

Hey folks, super new to HA. I’m getting closer to having everything configured the way I want it but having a slight issue with the columns. From the post here it was said that every 300 pixels there should be a column added. However this is, intermittent at best, on my 900px laptop. It was showing the third column for a bit but now it’s back to only two. Any idea how I can solve this? Thanks so much!

For clarification, 1600 x 900 is 1600 pixels wide, 900 pixels high, regardless, if there should be a new column every 300px, then I would expect at least a 3rd column with 1600px wide.

lol yes, I’m an idiot. Regardless I should have another column though. And for a while I did, now it’s back to not there though. :confused:
