You're are almost using the correct three jQuery methods. However, there are a couple issues. First, you're not using them in the correct order. The challenge wants the element hidden, and then after 2 seconds wants the element to "fadeIn". Note that it is fadeIn() with a capital "I". The second issue is that you're not chaining the methods:

$('.profile-header').hide().delay(2000).fadein();

Hi Hadar, your Javascript code is fine. You just didn't do exactly what the challenge requested. Instead of writing each line of code like you did, you're meant to chain them to each other(this is possible in jQuery) in a single line like this:

$('.profile-header').hide().delay(2000).fadeIn();

This is a method in jQuery called 'chaining'. Applying various methods to a single or group of selected elements. And you didn't spell the 'fadeIn()' method correctly, you used small letter 'i' instead of capital letter 'I'(camel casing).

Hey Hadar,

In jQuery you can chain multiple methods, so the answer should be:

$('.profile-header').hide().delay(2000).fadeIn();
