Example 1: css select all siblings after element

/*To match to any sibling element after the selector on the left,
  use the tilde symbol '~'. This is called the general sibling combinator. */

selectors and matches the second element only if 
it immediately follows the first element, and
both are children of the same parent element.*/

<ul>
  <li>One</li> // The sibling 
  <li>Two</li> // This adjacent sibling will be red
  <li>Three</li>
