Java Script blocks all animations

Dear community,

first of all i want to say sorry for my english skills, im from germany.

I am building a homepage with divi and everything is fine until last week.
I tried my first steps with javascript to make an element sticky.

It worked really fine everything! Now, a few days later, i have big problems:
As soon as i add ANY kind of javascript for example

<script src="http://YOUR-DOMAIN-HERE/wp-content/themes/YOUR-THEME-FOLDER-NAME-HERE/js/jquery.sticky.js"></script> <script> jQuery(document).ready(function(){ jQuery("#sticker").sticky({topSpacing:200});
});
</script>

(i checked that the jquery part script disables all my animations, the first part doesnt touch anything)

ALL moduls with animations (made by divi builder) disappear, if i exit the visual builder. In the visual builder i can still see these moduls, but if i leave... and java script is also not working.

I tried everything, i deactivated ALL plugins and so on.. anything blocks all other java scripts if i add own script in the header by using divi settings -> integration.


Do you have any idea why this happens?
