MDN’s new design is in Beta! A sneak peek:

3D view

Cuando das click sobre el botón ver 3D view, la página entra en modo de vista 3D; en este modo, usted puede ver su página en vista 3D en la cual se anidan bloques de HTML que van sobreponiendose, se proyecta desde la parte inferior de la página. Esta vista hace fácil de visualizar como se anida su contenido.

By clicking and dragging the view, you can rotate and re-orient the 3D presentation of the DOM hierarchy of your page to see it from different angles, to better examine its structure. Off-screen elements become visible, so that you can see where your elements are located in relation to the visible content. You can click on elements to see their HTML in the HTML panel or or Style panel. Conversely, you can click on elements in the breadcrumb bar to change which element is selected in the 3D view.

If you do not see the 3D button in the page inspector, it is possible that your graphics driver needs to be updated. See the blocklisted drivers page for more information.

Controlling the 3D view

There are keyboard shortcuts and mouse controls available for the 3D view.

Function Keyboard Mouse
Zoom in/out + / - Scroll wheel up/down
Rotate left/right a / d Mouse left/right
Rotate up/down w / s Mouse up/down
Pan left/right ← / → Mouse left/right
Pan up/down ↑ / ↓ Mouse up/down
Reset zoom level 0 Resets the zoom level to the default
Focus on selected node f Makes sure the currently selected node is visible
Reset view r Resets zoom, rotation, and panning to the default
Hide current node x Makes the currently selected node invisible; this can be helpful if you need to get at a node that's obscured

Use cases for the 3D view

There are a variety of ways the 3D view is useful:

  • If you have broken HTML causing layout problems, looking at the 3D view can help find where you've gone wrong. Often, layout problems are caused by improper nesting of content. This can become much more obvious when looking at the 3D view and seeing where your elements are nested wrong.
  • If content isn't displaying, you may be able to figure out why; since the 3D view lets you zoom out to see elements that are rendering outside the visible area of the page, you can find stray content this way.
  • You can get a look at how your page is structured to see if there may be ways to optimize your layout.
  • And, of course, it looks awesome.
