Code Switcher
Code Switching Example #
This is an example of a code switcher between multiple different snippets of code. Pretend they’re all the same logic even though they’re just here for demonstration of the tab switcher and coming from different domains.
There is also has a feature of allowing specific page links to activate/override the tabs a little bit too. Try it out with these buttons below and then look at the URL in your browser.
Hand writing the CSS styles for the different tabs is a bit of a pain, but thankfully this is wrapped in a custom Hugo Shortcode I made so that I don’t have to think about it too much.
