Fixes the items that were supposed to be set as a row of three on wider
screens. Also fixes the video width, so that it doesn't run of the side
of the browser.

 HortaCloud software provides an efficient production environment for collaborative and accurate reconstruction of long range projection neurons in light microscopy data. This software, originally developed for Janelia's MouseLight Team Project, has allowed annotators to efficiently reconstruct entire axonal arbors of individual neurons from whole-brain light microscopy data.
