Z index problem

I want to have a full page slider with a heading placed on top of the slider. Pretty basic stuff.

So…

I have designed a page with a slider which is set to position: relative
Then I set a sibling div block set to position: absolute. With a heading placed inside.

I need to be able to set the z index but Webflow style panel doesn’t have an input field that lets me set the z-index.

All the tutorials have an input field. But not for me. I can’t work out what I’m doing wrong. I’ve searched the forums but no one seems to have this problem. So I must be doing something wrong here.

I’m a noobie boobie… help!

Thanks
Hannah
