Are you tired of elements overlapping and not appearing in the desired order on your web page? Well, as you are using TailwindCSS, you can use powerful z-index
utilities. In this complete guide, you’ll learn how to effectively use z-index
in TailwindCSS to control the stack order of elements and overcome common challenges.
Understanding the Basics of Z-index
Z-index determines the order in which elements are displayed on the z-axis. It allows you to position elements in front or behind other elements. You can read the official documentation of z-index
on mozzila docs.
Using Z-index in TailwindCSS
TailwindCSS simplifies the process of working with z-index by providing a range of utility classes. All the classes for z-index
are prefixed with z-
, that you can apply directly to your HTML elements.
To apply a specific z-index
to an element, you can simply add the corresponding utility class to its HTML tag. Here is an example of using z-index
in TailwindCSS.

<div class="z-40">05</div> <div class="z-30">04</div> <div class="z-20">03</div> <div class="z-10">02</div> <div class="z-0">01</div> |
Negative Z-index Values in TailwindCSS
Sometimes, you may need to position an element behind its parent or other elements. TailwindCSS allows you to use negative z-index
values by prefixing the class name with a dash. Here is an example of using negative z-index
in TailwindCSS.

<div class="-z-50"> </div> |
You can read more about z-index
classes on TailwindCSS documentation.
Why z-index
is Not working in TailwindCSS
The z-index
is a powerful tool, it’s important to understand that it might not always produce the desired outcome. Here are a few common reasons why z-index
might not work as expected:
- Contextual Limitations: Z-index values work within the context of their parent elements. If an element has a lower
z-index
value than its parent, it cannot overlap other sibling elements that fall outside its parent’s stacking context. - Positioning: Z-index only works on elements with a defined position property, such as
relative
,absolute
, orfixed
. Make sure you have correctly applied the appropriate positioning to your elements forz-index
to take effect. - Stacking Contexts:
z-index
is relative to the stacking context of an element. When dealing with nested elements, each parent element with a defined position establishes its own stacking context. Understanding the hierarchy of stacking contexts is crucial to achieving the desired visual result.
You can troubleshoot why z-index
is not working in your TailwindCSS by reading the above 3 important limitations.
Conclusion
You can use z-{value}
syntax to apply z-index
classes in TailwindCSS. TailwindCSS also provides classes for negative z-index
values which is very useful if you want to stack something behind other elements.
