Is it possible to select more than one element at a time in the Chrome Developer Tools Elements panel? Would be useful for deleting multiple sibling elements or quick re-ordering. I expected Command + Click or Shift + Click to do this but it didn't work.
The answer is NO, it is not possible to select more than one element at a time in the Chrome Dev-Tools. You may refer to the Chrome Dev-Tools Tips and Tricks https://developer.chrome.com/devtools/docs/tips-and-tricks
The Answer is NO: While you cannot select an arbitrary set of elements, you can modify settings of groups of elements indicated by tag or class.
Go to the parent that contains all of the html elements that you want to influence ... edit as html. Then you can modify everything inside however you want!
Old topic, just updating...the answer today in Nov 2017 is: YES, WE CAN!
No exactly copy all, but you can click on element and copy, so you can copy all inside it.
you can copy the entire html by right clicking on the highest html tag above and then select copy outer html(or copy as html in older versions)-> paste it in your code editor->save the document as .html ->click your formatter key combination to format the document(otherwise it would look terrible)->voila you can take whatever you need now.
