Linking third party CSS and JS files

[X3Technology]

What is the best way to link to a third-party CSS/JS file?

I would prefer the CSS to be in the HEAD section and the JS to be loaded async at the bottom of the page.

Functionality similar to DNN's CssInclude and JsInclude.

Use the header tags options available in Settings > SEO > Advanced to add tags to HEAD section. There's no option to add site level scripts at bottom of the page. I would create an issue for that as a feature request.

On page level, you can add it to a custom block and place towards the bottom of the page.

I like this suggestion as a work-around. I put a Custom Code block in my Custom Footer that goes on every page. In this Custom Code block I just have this:
<script src="/portals/_default/vThemes/Incline/assets/js/navbar.js"></script>
which is just some javascript to detect scroll position and change the background color of the nav section. This seems to work pretty well.

I put the CSS link in the SEO section like you said and that also seems to work.
