I am having some difficulty getting a grid system to work within a div. My entire page is a grid which worked fine: https://codepen.io/jamster1/pen/KXgpmB, but when trying to employ another grid, within it, it doesn’t seem to work. I have placed the section with just the grid at this link: https://codepen.io/jamster1/pen/LzzRQY to test out what could be wrong, but I am unable to figure it out. I have tried many things such as subgrid, inline-grid, changing postion, display…etc. Any help or guidance would be much appreciated! To be more detailed, I am using the h1 hello elements as a substitute for now, but they appear to the right of the div called portfolio holder, instead of in it.
