jquery $ is undefined

I used the LayerList widget and got it to work. Then, I tried adding jquery code with a slide toggle so that the LayerList could be displayed and then hidden so that more of the map was visible. However, I am getting an error when I try to view my html saying that the "$ is undefined" in my $(document).ready() statement. My html is attached.

I made a rookie mistake. The link href= and the script src= were not listed as a URL, but instead were referencing folders within a specific Visual Studio solution.

Instead of hosting jQuery, you can reference the CDNs:

jQuery CDN

This has the added benefit that it'll increase the likelihood of your visitors already having a cached instance of jQuery. It may not make a difference in your case, though. It can be quite noticeable in scale, however.
