Just define the hr sytle in the settings and set up rows in the gridder.
Page should have no (left & right) frame to make the lines go border to border of the viewport.
Add Project-Thumnail in the first column of each gridder-row and the text afterwords.
These steps should bring you pretty close. Rest ist fine-tuning and perhaps a wee bit of custom css – something like overflow-hidden etc. ‹— just guessing, here.
