Please could you create a video on this – far easier for me to visualize via a Video vs reading text.
One thing I noticed on your demo – was that I following this, I was left with 2 rows of 3 and another with 2 – leaving a blank column on the 3 rd row. I can see that I can drag the row3 col2 element to row3 col3 – thus filling up the “empty slot” – wow!!
Whoops, thanks for pointing that out. Youtube must have moved onto another video before I copied the link! I’ve update this now, with the correct link you found.
