Problem with selector in jQuery Project 1


Hello! In the fifth task of the first jQuery project - Bonsai we need to change "scr" attribute of "img" element which is a child of "div" element with class "meme thumbnail". I tried to select the exact element this way, but it doesn't work:

$('#image-url').keyup(function() {  
  	var imageUrl = $(this).val();
    $(' thumbnail > img').attr('src', imageUrl);


You will have to provide the FULL HTML, CSS and Javascript you are using....
