/*The general sibling selector selects all elements that are siblings of a specified element.
The following example selects all <p> elements that are siblings of <div> elements: */
/*<div></div>
  <p></p>*/
div ~ p{
}

/*Adjacent Sibling*/
/*The adjacent sibling selector is used to select an element that is directly after another specific element.
Sibling elements must have the same parent element, and "adjacent" means "immediately following".

/*<div><p></p></div>
  */
div + p{
}
