When should I use Z index?
If you want to create a custom stacking order, you can use the z-index property on a positioned element. The z-index property can be specified with an integer value (positive, zero, or negative), which represents the position of the element along the z-axis.
What is Z index and how does it work?
The z-index property determines the stack level of an HTML element. The “stack level” refers to the element’s position on the Z axis (as opposed to the X axis or Y axis). A higher value means the element will be closer to the top of the stacking order. This stacking order runs perpendicular to the display, or viewport.
What is Z Index 9999?
CSS layer refer to applying z-index property to element that overlap to another element. CSS z-index property always work with absolute as well as relative positioning value. CSS z-index possible value 0, positive (1 to 9999) and negative (-1 to -9999) value to set an element.
What do you mean by Z indexing explain how it is used for layering?
The z-index attribute lets you adjust the order of the layering of objects when rendering content. In CSS 2.1, each box has a position in three dimensions. The Z position of each layer is expressed as an integer representing the stacking order for rendering. Greater numbers mean closer to the observer.
Is Z-Index inherited?
No, it isn’t inherited. You can see it in MDN article. However, be aware that z-index sets the z-position relatively to the stacking context. And a positioned element with non auto z-index will create an stacking context.
How do you avoid Z-index?
Take-aways
- Understand how stacking works, and use the rules to your advantage to avoid using z-index , as long as it makes sense.
- Keep z-index values low: you’ll rarely need more than z-index: 1 (or less than z-index: -1 )
- Create stacking contexts to keep things boxed and prevent them from interfering with each other.
What is Z ordering?
Z-order is an ordering of overlapping two-dimensional objects, such as windows in a stacking window manager, shapes in a vector graphics editor, or objects in a 3D application. One of the features of a typical GUI is that windows may overlap, so that one window hides part or all of another.
What is the highest Z-index?

What is z index HTML?
Z-Index is the property of CSS which is used to order the elements behind and in front in the form of stack. You can consider this a virtual stack where the higher value of z-index is placed infront and the lower value of z index is placed at the back.
