/*
 * HACK: centered-footer
 *
 * When someone likes a message we want to submit the form and then redirect
 * them back to the original page. Unfortunately when you link to anchor tags
 * that scrolls the browser so that they're at the *top* of the page, not the
 * center of the page. In our view we have an empty div with an appropriate
 * anchor tag, so here we use CSS to center it on the screen.
 *
 * The code below creates padding-top that takes up 50% of the height of the
 * viewport and then gets rid of it with negative margin. This has no effect
 * on the display of the item, but means that when we link to the anchor tag
 * it centers this empty element vertically on the screen.
 *
 * We also use `pointer-events: none` to ensure that this invisible div doesn't
 * capture cursor events (clicks, drags, etc) on surrounding elements, because
 * otherwise we could have a problem where someone clicks above the invisible
 * div but the browser things they're clicking the gigantic amount of padding.
