Implemented temporary fix for #147

Fixes #147 (closed)

Comment from source code:

`transform: translateX(0)` fixes an issue on webkit browser
where relative positioned elements aren't displayed in containers
with multiple columns. This is a quick-fix as pointed out on the
webkit bug reporting platform.

It seems like there is a fix live in Safari Technology Preview
This fix should be left in here until the fix is published for
Safari iOS + macOS
