Issue with z-index not applying to a fixed header

I've been attempting to recreate the problem using this plunker.

.demo-blog.mdl-layout .mdl-layout__content {
    padding-top: 0px;
    position: relative;
    margin-top: -80px;
    z-index: 100;
}

header.main-header{
  z-index: -50;
}

My goal is for the "on the road again" div to appear on top of the header that says "evolution update". I've tried adjusting the parent's z-index, altering each associated unit's z-index, wrapping the header in a div tag, but nothing seems to be working. The "on the road again" div continues to linger behind the header.

This is what I'm aiming for: this.

Thank you in advance for your assistance.

Answer №1

Utilized the z-index in conjunction with position, but without using position, it does not function as expected.

The z-index property determines the stacking order of an element.

Please note: The z-index attribute only affects positioned elements

(position:absolute, position:relative, or position:fixed)
.

Answer №2

To address this issue, simply include the following CSS rule: margin-top: -60px; within the styling for the .demo-blog class.
