* Hello there!
* I suppose this is a pretty newbie question, but I just can’t figure it out… I
would like to use a script to determine the window width dynamically in my template
and load a different css. This is the script I’m using:
* ```
function adjustStyle(width) {
width = parseInt(width);
if (width < 1010) {
$("#size-stylesheet").attr("href", "css/narrow.css");
} else {
$("#size-stylesheet").attr("href", "css/wide.css");
}
}
$(function() {
adjustStyle($(this).width());
$(window).resize(function() {
adjustStyle($(this).width());
});
});
```
* The code is in the file resolution-test.js
* I’m using the following code in my header.php:
* ```
```
* I do know about the noConflict mode in WordPress, so I tried changing the JavaScript
Code in the following way:
* ```
jQuery(document).ready(function(){
function adjustStyle(width) {
width = parseInt(width);
if (width < 1010) {
$("#size-stylesheet").attr("href", "css/narrow.css");
} else {
$("#size-stylesheet").attr("href", "css/wide.css");
}
}
$(function() {
adjustStyle($(this).width());
$(window).resize(function() {
adjustStyle($(this).width());
});
});
});
```
* It still doesn’t work. What am doing wrong? Thanks in advance!

* Is it actually being enqueued / do you have a _wp\_head();_ call in there?

* Thank you for the answer!
You are right, indeed I forgot to include the call.
Now that I’ve changed the header.php file my output looks like this:
* ```
Testseite
```
* A lot of scripts are now included, also the resolution test, but it is still
not working…

* I now tried to include a very simple script to output an alert with “Hello world”,
but it also doesn’t work… Scripts do show up in the header, but they are not
executed…

* A syntax error elsewhere could be causing problems – perhaps you could share
a link?

* Sorry for the late answer…
I did find a syntax error. My theme was missing the
footer hook, but actually it should have not affected the code in the header?…
Well, in the end I got rid of the javascript and used media queries instead.
