Append a style on click, then append another style on 2nd click

Here is my code:

When i click to, suppose "show div 1", it removes dotted border-bottom of it but once it clicked again the border does not return whereas what i want it does.


Use toggleClass that should do the trick. You're doing an each() which may not be needed. Just hook onto the element that needs to be clicked. Don't need to loop through each parent li etc.

See the first example here:

I'd suggest you use classes to manage it as it is much cleaner:

$('#element').click(function() {
  if ($(this).hasClass('class1')) {

With styles it is similar. An example:

$('#element').click(function() {
  if ($(this).css('background-color')=='red') {
    $(this).css('color', 'white');
