I was asked:
Which jQuery method is used to switch between adding/removing one or more classes (for CSS) from selected elements?
The answer to this query is .toggleClass() method of jQuery.
For example, if we have a div like this:
<div class="original">Some text here</div>
Now if we add this to jquery:
It will change our div’s html code to:
<div class="original added">Some text here</div>
If we apply the same jQuery again the second time to this new code, it will toggle it back to the original version.
