may help you . you could achieve that but you will need to but you will need to move the #middle div inside #outer for the z-index to work
code :
div {
  position: absolute;
#outer {
  width: 300px;
  height: 100px;
  top: 20px;
  background: yellow;
#inner {
  width: 240px;
  height: 80px;
  top: 10px;
  left: 30px;
  background: green;
  z-index: 2;
#middle {
  width: 280px;
  height: 140px;
  left: 10px;
  z-index: 1;
  background: blue;
  top: -16px;
<div id="outer">
  <div id="inner"></div>
  <div id="middle"></div>

hope this fix your issue Yes, they are different.
An index on (A, B) will contain the A,B combination as the index key, meaning it shows up on every non-leaf page. An index on (A) include (B) will contain only A as the index key, so B will be present only on leaf pages, while non-leaf pages will contain only A.
Hover events on element covered by higher z-index?

Hover events on element covered by higher z-index?

like below fixes the issue Try using pointer-events: none. This rule tells the browser to ignore an element. Mouse events won't be received by it, but will 'pass through'.
code :
#canvas-mouse {
    z-index: 10;
    pointer-events: none;
Element covered by navbar with higher z-index

Hope that helps I have a navbar with a z-index that is above/higher all other elements on a page, which means it is "ignored". Its height is not counted on the page. , I used to use a small trick (I think it still works), just do:
code :
<div id="mydiv" class="section-target"></div>
.section-target {
    margin-top: -40px ; // Change to your navbar height
    padding-top: 40px ;

hop of those help? I ran into a similar requirement recently. I do not have the complete solution implemented yet but at a high level these are the steps I am taking. To verify element A is not overlapped by any other element
Get the element in question, bind the click() event of the element to a function that does nothing. Click on 9 points of the element - center; top: left, center, right; middle: left, right; bottom: left, center, right. Selenium clicks on an element at the center point by default. The other points can be calculated by DOM positioning of the element and then moving to the respective points. Wrap the call block in step 2 in a try/catch to check for Element not clickable... exception. If an exception is thrown, element is overlapped by another at one of the click points.
Plotband covered area columns to be highlighted or set opacity higher in highchart column type

Plotband covered area columns to be highlighted or set opacity higher in highchart column type

Does that help Try this idea:
First, give the plot bands a higher zIndex by default (say, zIndex: 10). This will place them on top of the columns. Next, change the color of the plot bands to white and set the opacity to 0.4. This will give you the "faded" look you have in your image example. Whenever the user hovers over (mouseover) or clicks on a column, change the zIndex of that specific plot band to 0 (moving it back under the column), change the color to gray, and set the opacity to 1. When the user moves their mouse off the column (mouseout), go back to the zIndex of 10, the white color, and the 0.4 opacity.
code :
    plotBands: [{
        color: 'rgba(255,255,255,0.8)',
        label: {
            text: 'Section 1'
        from: -0.5,
        to: 0.5,
        events: {
            click: plotbandclick,
            mouseover: plotbandmouseover,
            mouseout: plotbandmouseout
        zIndex: 10
    }, {
chart: {
    renderTo: 'container',
    defaultSeriesType: 'column',
    plotBackgroundColor: '#e9e9e9'
    fill: rgba(255,255,255,0);
    fill: rgba(255,255,255,0);
