What am I doing wrong with this simple jQuery statement to set CSS height?

Question

I wonder if anyne can help with this jQuery issue...

I am trying to set the height of a div layer on my site.

I am using this command

var test_height = 200;
$("div#wrapper-holder").height(test_height);

...but nothing seems to be happening. What am I doing wrong??

The page in context is here: http://bit.ly/1ar6KuR

Many thanks for any help that you can give...

Nothing to see here.... (rest of comment is void) `.height()` doesn't take any arguments, it's a getter only (http://api.jquery.com/height/) You're after [`.css()`](http://api.jquery.com/css/) — MDEV, Sep 26 '13 at 16:04

wrapper-holder is class not id.

i checked it in your site

class is used as add . before class name

 .wrapper-holder
 ^

you code

var test_height = 200;
$("div.wrapper-holder").height(test_height);
  ^ //changed #(id-selector) to .(class-selector)

You were using an ID selector (#selector) on a class element.

<div class="wrapper-holder"> has either to be changed to <div id="wrapper-holder">

Or

var test_height = 200;
$("div#wrapper-holder").height(test_height);

has to be changed to

var test_height = 200;
$("div.wrapper-holder").height(test_height);
