Three Column Grid Help

I chose this template because I loved the mosaic three column grid to display projects, but after adding content and shifting things around, I may have inadvertently changed some of the properties on the grid which affected the positioning and spacing of the columns. I’ve uploaded a pic below to show the unequal column spacing I have now. Ideally, I would like the columns to look like the second image with equal spacing that isn’t too wide.

Can anyone help me get this straightened out?

If its one row 3 Columns i would have Flex

It’s actually three columns with multiple rows.

Any suggestions as to how to make the column widths equal to one another?

You can have a div as a wrapper for all data in your column and set it to 33%
