How do I use the Inspector?

The Inspector can be divided into two main sections: the DOM section and Pane’s section.

DOM Section

The DOM section displays the rendered HTML code in an expandable tree format, and the code is also color-coded to increase readability. You can edit the DOM directly here, and the changes will be reflected in the webpage instantly. You can add breakpoints, focus on particular elements, or force the state of that element in this section.

DOM section

At the top of the DOM sections, you get various options. Let’s move left to right and understand each option.

  • Search HTML: You can search nodes, attributes, and text in the rendered DOM of the web page. You can use the shortcut “Ctrl+F” to focus on the search bar.
  • Create a New Node: Select an element in the DOM section and press this button. You will see a new node being created, which is by default a div. Double-click this node and change the node to whatever you like, and then press enter.
  • Grab a color from the page: It works as an eyedropper tool that can be used to select a pixel from the web page, which copies the color hex value to the clipboard.
