There are parts of a webpage which you do not want to really use. For example when you see a Facebook public post or profile, it also shows a login box, which you might not be interested in.
For instance in the example below, I will be removing the highlighted element or part from the webpage I am viewing.
I am using Chrome extension Dynamite to show how it works. Just right-click on a selection select Dynamite icon and select hide element.
The end result that element from the webpage is removed immediately.
Ideally, these are very useful tool for web designers to check how the webpage would look by removing certain elements.
