This style apply by default to all slides, unless .slide is used.
Note the use of the reveal class selector: this mean that only the presentation is affected by this style, and the makrdown preview or the book mode of hackmd.io is style intact.
If you want/need a resizable background image, add the background-size: cover; property and change background-position: 0px 0px;
