#Layers Panel

The Layers panel helps you understand the composition of Lynx pages and how the framework presents content, analyzing its 3D layers to discover rendering issues.

#Overview

Or, select the More options in the upper right corner -> More tools -> Layers.

#View page Layers

The leftmost part of the Layers panel lists all the rendered layers of the Lynx page in an expandable tree. This tree structure is updated as the mobile Lynx page is updated. Layers are identified by their CSS selector or a number (followed by the layer size in pixels).

Hover the mouse over a layer to highlight it on the Lynx page preview window. A tooltip will be displayed on the page preview, which contains the following information:

• The selector of the layer
• The size of the layer (in pixels)

#Inspect page Layers

Click on a layer to view more information in the Details pane.

Depending on the layer, the following information will be displayed:

• Size

• Memory estimate
• Number of draws

The following figure shows the stacking and arrangement of the layers of this Lynx page.
