Unexpected issue with accessing the jQuery class descendant

I am currently developing a photo gallery and I am trying to add some CSS styling to the first photo that is visible within my #wrapper div. Below is the code snippet I have been working on:

$('.inside:first-of-type>div:nth-of-type(1)').css('display', 'none');
$('.inside:first-of-type>div:nth-of-type(2)').css('display', 'block');

All elements that are within view of the #wrapper div are given the class .inside, which is removed once they slide outside the #wrapper. Each photo consists of two div layers. In this particular case, I want to hide the first layer and display the second one. The current code seems to work when the first photo in the sequence is visible, but does nothing if it's not.

Do you think there might be an issue with my CSS code?

Answer №1

Unfortunately, the first-of-type selector is not supported in jQuery or most browsers.

To achieve what you are looking for, you can do the following:

var items = $('#wrapper .inside > div');
items.eq(0).css('display', 'none');
items.eq(1).css('display', 'block');

Here are some additional tips:

  • It's recommended to cache the selector result to avoid redundant DOM queries.
  • You can simplify hiding the first div using the hide function: items.eq(0).hide();
  • If you want to hide the first and remove the second layer, using .css('display', 'block'); won't remove anything. Consider using the remove function instead: items.eq(1).remove();
