NES.css adapter breaks on mobile — hamburger menu invisible

Running the NES.css adapter on Joomla 6. Desktop looks amazing — full 8-bit aesthetic. But on mobile the hamburger menu icon is invisible. The three lines do not show.

I think it is because NES.css overrides the background color on all elements and the hamburger spans get lost.

Anyone else seen this?

Known issue. NES.css sets a global background that conflicts with the hamburger span background color.

Fix in your adapter CSS or custom.css:

The !important is needed because NES.css has high specificity on its global rules. Should be fixed in the next BaseFrame release.

Can confirm — same issue on the Chota adapter . Any micro framework that resets html font-size to 62.5% or overrides body/html properties aggressively will cause hamburger visibility issues.

The base.css fix for this shipped in v1.3.0: plus the box-sizing reset. But the per-adapter hamburger color still needs explicit overrides in some cases.
