Okay, this is a sweet set of styles for making any navigation centered and 100% width, using a justify trick.
Works no problem in codepen, or a flatfile. It does NOT work on a Joomla install. This blows my noodle, how is that even possible? That's like the color red not working. Can anyone think of why it would fail on Joomla, or how exactly I could get it to work?
The More information requested:
We use our own custom template. We have a template we call 'base' with all our code in less, compiling to the css. If I use this, removing all ul styles and all body styles, it still doesn't work. I can remove bootstrap, it doesn't make a difference.
New Information: I've done this two ways - totally works in a Joomla Article. Totally doesn't work with a Joomla Menu uls. I've used the exact same code, put them side by side, but piping it through the menu module breaks it. That is completely weird. There is no visible difference between the two. When I copy the menu UL and move it into the article, as is, it doesn't work. When I remove the class="item-#" off the li, it doesn't work. This is mind blowing. They are identical!!!
