The CSS rules visibility:hidden and display:none both result in the element not being visible. Are these synonyms?
display:none; will neither display the element nor will it allot space for the element on the page whereas visibility:hidden; will not display the element on the page but will allot space on the page.
We can access the element in DOM in both cases.
To understand it in a better way please look at the following code:
