Check out my site; http://sequoiasystems.org.
I included a a privacy alert because of new EU Regulation, but the alert goes behind some of my website components like other DIVs and Revolution slider...
I have tried some CSS, but nothing seems to work.
You can probably fix it by giving it a high z-index. You can do it two ways.
1.) Use inline style attribute:
<div id="myDiv" style="z-index:100;">This is my privacy warning</div>
2.) Use CSS with a class:
.myclass {
z-index: 100;
}
<div id="myDiv" class="myClass">This is my privacy warning</div>
