I have a text splitted in 4 columns and it works perfectly in Safari I don\'t know why I can see just 2 columns in Google Chrome.
Tested with Chrome 55.0.2883.95 (64
I used a similar method for a WordPress theme. It looks pretty good in Firefox and displays two columns in place of four in Chromium/Chrome for full screen width.
When I increased the number of posts per page (bricks), the number of columns increased to fill up the space.
Chrome seems to render three or more bricks before graduating up to the next column.
