You went from ImageGallery in your html which is different spelling from imageGallery which is used in the jQuery call to "image Gallery" which is actually more wrong lol.

The correct spellilng is imageGallery. ImageGallery is wrong because it has a capital I in image and image Gallery is wrong because that's TWO words. By typing class="image Gallery" you're literally giving it two classes. 

//notice the spelling. One word... lowercase i
$("imageGallery a");

<!-- mistake #1 you capitalize the letter I -->
<ul class="ImageGallery"></ul>

<!-- mistake #2 you make one word into two thereby creating two separate classes -->
<ul class="image Gallery"></ul>

<!-- only correct way in regard to making it the same as the JS spelling ... one word, camelCase -->
<ul class="imageGallery"></ul>

Cheers,

Huck - :sunglasses:

I noticed the div id has a capital "I" and "G", but your jquery selector only has the "G" capitalized.

Your code is correct, but for the challenge, you're not asked to console.log() href.

I had the same problem for a long time. I can't explain why, but here is what worked for me… I changed the quote marks that are around $("#imageGallery a") from double quote marks to single quote marks $('#imageGallery a') and it worked. Even more bizarre is that I changed them back to double and it still works.

i noticed when i changed it from double to single it changes some of the text colors. and those new colors are there when i switched back..... also i didn't know that the hashtag was mandatory... Thanks!

I also had this same problem and all I did is add two spaces between "imageGallery" and "a". Like this...... $("#imageGallery a")
