custom text fields, worpress page

Hi,

Is there any plugin, user friendly or with easy to set manual for custom fields on wordpress page?

I installed a few (Savvii Custom Post Widget, Multiple content blocks, Table of Contents Plus….) but it seems that there is no easy way to set 3 or 4 text blocks horizontally across the page width, side by side with 2-3 sentences in it, and link read more at the and of the text.

The same style as on: https://www.partyplans.com.au/

look at the bottom of the page.

btw, unfortunately I’m not that much into codes or programming
