The Layers panel lets you manage your design more easily by assembling layer content onto separate layers, each layer being independently controlled.
About the Layers panel
Layers are composited together to form your complete design which shows up on your page.
The panel can be used to build up your design as multiple layers, with each layer devoted to a particular facet (e.g., brush strokes, images, adjustments, as well as vector shape, line and text).
From the Layers panel you can:
Create or delete layers
Apply blend modes to layers
Arrange and reorder layers
Select layers
Show and hide layers
Group layers
Lock layers
Clip layers
Create masks
Add layer adjustments, effects, and filters
Tag layers with a choice of colours
Change the UI display colour of all object's path, nodes and handles
Exclude layer from being a snapping candidate (right-click object only)
Switch off Auto-scroll (panel scrolls to layer content when it is selected on the page)
Display layer thumbnails with a solid or checkerboard background
Determine the size of layer thumbnails
The panel displays the following:
