Do we not have the ability to add class and id selectors to custom HTML and then target them in CSS?

No, you can’t add classes or IDs using the standard version, but you can target specific classes on certain pages using collection and item IDs or classes.

I have been trying to add a class to my Google Social Link so that I can update the icon. Squarespace uses a generic URL icon for Google link for some reason??

I have been able to select the links using querySelectorAll but it wont let me add a class to the elements. The console says .addClass and .classList.add are not functions. 

Did you ever find a solution?

Try this plugin (I haven't used yet) https://www.squarewebsites.org/products/blocks-classes
