Title: Modern CSS with Tailwind Second Edition: Menu Close Not Hiding when Should (pages 65-66)

After fixing the SVG icons to be ones that show up for me, since the code in the book did not work on my computer by default, it turned out that the close icon would display on first render even when the hamburger menu was displaying. When I would open the hamburger menu and then close for the first time then the menu icons would work as expected so this is due to hidden class not being on the “navbar-close” element. When I added the “hidden” class to it then everything worked perfectly.

I also had to run ./tailwindcss -o css/output.css to get everything to work right. I added this example to the test.html example in the code directory.

Here’s the HTML code that worked for me:
