关于DevTools检查面板Tabs组件名称及代码查看方法的问询

Hey there! Let's break down your questions one by one:

1. What's the name of the Tabs component in the DevTools Inspect panel? #

In most modern browsers (like Chrome, Edge, which share the same DevTools core), the Tabs component that switches between panels (Elements, Console, Sources, etc.) in the Inspect panel has these key identifiers in its internal DOM:

• The container holding all tabs uses the class name .devtools-tabs
• Individual tab items use the class name .devtools-tab
  Officially, this component is often referred to as the Panel Switcher Tabs in DevTools documentation, but the DOM-level identifiers are the most concrete way to reference it.

2. What's the name of the Tabs component marked by the red circle? #

Since I can't see the screenshot, let's cover the most common scenario: if the red circle is highlighting one of the individual panel tabs (like the "Elements" or "Console" tab), that's a .devtools-tab element as mentioned above. If it's the entire tab bar, it's the .devtools-tabs container.

How to view the panel's HTML code and styles if you can't directly access the Tabs component? #

You need to inspect the DevTools itself—here's how:

• First, open your regular DevTools (press F12 or Ctrl+Shift+I on Windows/Linux, Cmd+Opt+I on Mac)
• To open the DevTools for your DevTools:
  • If your DevTools is in an undocked window: Right-click anywhere in the DevTools UI and select Inspect
  • If it's docked: Press Ctrl+Shift+I (Windows/Linux) or Cmd+Opt+I (Mac) again to launch the nested DevTools
• Once you have this nested DevTools open, you can navigate its Elements panel to view the full HTML structure of the original DevTools (including the Tabs component), and use the Styles panel to examine all associated CSS rules.
