re-apply css filter: greyscale(1) on hover out of description
To correlate the left and right column of the site, hovering over the vignette highlights corresponding text and hovering over a description highlights the corresponding vignette.
I try to do this here: https://gitlab.constantvzw.org/diversions/diversions-2019.collection-incertitudes/blob/master/static/build/main.js#L32
But it currently does not work, probably a simple css targeting issue.
