CSS/JS Solution: On hover of child element, change parent div

Question

I know CSS is \"cascading\", but in this case I want the effect to ascend. I\'m open for either a JS or CSS solution, but honestly I\'d prefer the solution with the least a

Answer 1

True;

#word #h:hover {
    background-color: rgba(0, 102, 0, .5); 
}

False;

#h:hover #word{
    background-color: rgba(0, 102, 0, .5);
}

Answer 2

The solution would probably be JS:

$(".letter").hover(function() {
    $(this).closest("#word").toggleClass("hovered")
});

Answer 3

In POJS, add the following

CSS

.wordBg {
    background: rgba(0, 102, 0, .5) !important;
}

Javascript

var changeWordBg = (function (word) {
    return function (evt) {
        if (evt.target.classList.contains("letter")) {
            switch (evt.type) {
                case "mouseover":
                    word.classList.add("wordBg");
                    break;
                case "mouseout":
                    word.classList.remove("wordBg");
                    break;
                default:
            }
        }
    };
}(document.getElementById("word")));

document.body.addEventListener("mouseover", changeWordBg, false);
document.body.addEventListener("mouseout", changeWordBg, false);

It can be done in pure JS, no jQuery (I assume you don't want that since it wouldn't be that light in code), this is the best I could came out with:

var word = document.getElementsByClassName("letter");
for (i=0; i<word.length; i++) {
  word[i].addEventListener("mouseenter", function( event ) {
    parent = event.target.parentNode.parentNode;
    //whenever the mouse hovers over a letter this will be evaluated once 
    parent.style.backgroundColor = "green";
  });
  word[i].addEventListener("mouseout", function( event ) {
    parent = event.target.parentNode.parentNode;
    //whenever the mouse hovers over a letter this will be evaluated once 
    parent.style.backgroundColor = "";
  });
}

A without jquery solution:

onload = function()
{
  var links = document.getElementsByTagName('a');
  for (var i = 0; i < links.length; ++i)
  {
    if (links[i].className == 'letter')
    {
      links[i].onmouseover = function() {
        document.getElementById('word').style.backgroundColor="#0000FF";
      };
      links[i].onmouseout = function() {
        document.getElementById('word').style.backgroundColor="#FFFFFF";
      };
    }
  }
}
