在子元素后面制作父 div

Question

I'm using jQuery.Gantt in a project and I need do many customization in this plugin.
One of this is pass mouse over an element (blue cells) and show a tooltip (in example I put a title).
I have some divs that "highlight" weekends and these divs is over gantt elements (blue cells)
If I change z-index of cells they will overlay the header (month and day) in horizontal scroll. I trying to find a way to get the following order: weekend div with z-index 0 , gantt cells (blue) with z-index 1 and header with z-index 2 . I need this order to display the title on gantt cells and use mouseover event on weekend cells.
How can I achieve this with the example below?

 .dataPanel { outline: 1px solid #DDD; background-position-y: 15px; background-size: 30px 48px; background-image: linear-gradient(to left, rgba(153, 152, 153, 0.7) 1px, transparent 1px), linear-gradient(0deg, #E7ECEF 0%, #E7ECEF 53%, #ECF1F4 53%, #ECF1F4 100%); background-repeat: repeat; position: relative; font-family: 'Verdana, sans-serif'; } .header { position: sticky; top: 0; z-index: 600; width: 241px; background: #fff; height: 63px; } .row { float: left; height: 24px; line-height: 24px; margin: 0; } .dayPosition { top: 46px; } .monthPosition { top: 15px; } .day { background-color: #fff; width: 24px; line-height: 24px; text-align: center; border-bottom: 1px solid #DDD; border-right: 1px solid #DDD; font-size: 10px; color: #007E7A; } .row .sa, .row .sn, .row .wd { height: 24px; text-align: center; width: 29px; } .bar { background-color: #D0E4FD; height: 18px; margin: 0 3px 3px 0; position: absolute; text-align: center; box-shadow: 0 0 1px rgba(0, 0, 0, 0.25) inset; border-radius: 3px; }

Answer 1

You just need to add pointer-events: none; to the overlay div.
