/* This is a tricky case.
 * We can't use `border-left` because sticky marker to the element looks kinda ugly.
 * We can't use `::before` pseudoelement because it requires `position: relative` of parent, which breaks side-image.
 * We can't use `outline` because it's impossible to display only left side of outline.
 * So... we need to use power of CSS hacks <3 and use doubled box-shadow.
