Elementor Pro provides grid containers as an experimental feature. The options provided are limited, when it comes to native controls. The fine-tuning of the grid container items need to be done using Advanced CSS.
If you are looking for a simpler way without using Advanced CSS, I started building out a Grid Tweaker for Elementor.
This will add a new tab to all containers and allows you to tweak grid-row / grid-column. Basic work is done. I am currently tweaking the controls a bit and will make it even easier ;)
Added an example template to import into Elementor. For those interested, the plugin can be freely downloaded from my Github repository. You can also do a search for “cubicfusion-grid-tweaker” on Github.
Cheers and enjoy
