html{
  /*background image properties*/
}

or

body{
  /*background image properties*/
}

Answer 1

body{
    background-image:url('../images/background.jpg');
    background-attachment:fixed;
    background-repeat: no-repeat;
    background-size: cover;
}

This would be the best way, you could apply it to the HTML, it really depends on what you prefer...

background-image:url('../images/background.jpg');

Assuming your css file is in a different map, you do ../ to go to the map in which your css folder is placed, then you go into the images file and select the image.

background-attachment:fixed;

When setting a background-image I personally like to use this, it makes it so that when a user scrolls, the background-image maintains it's current position.

background-repeat: no-repeat;

When using this setting, it makes it so that the image won't repeat, in case it is too small or just won't cover the whole background.

background-size: cover;

When you apply this you will set the background-size to cover, combined with no-repeat and attachment: fixed it makes for a good way to style your background image
