Help sidebar transition overlaying my collapse button

this project has a main page with a button in the upper right corner when click a sidebar is to transition in from the left 300px wide underneath the sidebar is an underlay set to transparent it will occupy 100% of the width it will prevent future controls from being edited while the sidebar is visible the button is to toggle the sidebar in/out but the underlay position is absolute and no matter what i set my buttons z-index to its still not clickable when the sidebar is out

basically i want the button clickable no matter what the state of the sidebar

See example here

You could just remove this: $("#underlay").toggleClass("slideoutunderlay"); The way it is set up right now would not be very user friendly. If you do need to keep your transparency underlay, I would recommend attaching the click button to the sidebar (edge of the sidebar like a tab perhaps) itself. This way you would still be able to keep everything else from being clicked on while the sidebar is open but you could still close it and the placement of the button would make more sense.

Glenn,

Even if my answer fixes the problem you should still take Chris' answer under consideration. The button that's opening and closing the sidebar probably should be close to what it is interacting with.

Presumably you're opening the sidebar to do something with it. So you have to move all the way to the top right to open it and then move back to the left to interact with it.

If you do make it part of the sidebar then you should be fine with your underlay having a z-index of 1 and the sidebar having a z-index of 2.

z-index has no effect on elements with static positioning.

You need to set a positioning context for your button so the z-index will work. Either relative, absolute, or fixed. Relative works here.

#btnEx {
  position: relative;
  z-index: 10;
}

Nice solution Jason! In this case, he wouldn't even need to include the z-index and it would still work.

I looked at it more closely based on Chris's comment and realized that you were trying to set the z-index on your #topdiv

I glossed over topdiv the first time around and didn't realize it's the container for the button. So that's fine you can do it there but again, you still need to set a positioning context.

#topdiv {
  position: relative;
    z-index:5;
}

However, this puts the div on top of the sidebar and it seems to block your link and button in the sidebar. Is that what you wanted?

If those should still be working then I recommend that you either use my original answer and assign the z-index to the button and not topdiv.

Or give topdiv a z-index of 2 and the sidebar a z index of 3. That puts topdiv on top of the underlay and the sidebar on top of topdiv.

Chris Dziewa Thanks!

the underlay has a z-index of 1 so wouldn't the button or it's container need to have a higher z-index in order to be above the underlay?

I might have missed what you meant in your comment.

Jason Anello I think the z-index property isn't needed because the button is an element with an id attribute that is inside another element with an id attribute. This could just be giving more specificity in the browser. This is only an educated guess though. Just setting the positioning property did everything that was needed when I tried it.

I hear you on the screen layout and design but the product owner wants the button in the upper right corner so it will be fixed in that location. In the next phase they want to add physics like animation to have it transition in out on a gesture type swipe. I'll try the positioning and z-index. I've learned something thx
