This is the first version of the grid set up. Arguably it’s the most interesting-looking, in terms of being able to span two items vertically or horizontally. But with that look comes a fair bit of cost in terms of time. You’ll certainly want to crop special images for each grid item, and set the size you want for each. But it gets tricky because depending on the screen size and number of columns, this layout is prone to get gaps in it, which isn’t something that can be fixed. I might be inclined to say that the Pinterest-style layout would be an easier option to manage, as you will only have gaps on the bottom, which we have ways of dealing with easily.
