Describe the issue

There are two small bugs inside these webpages published on bootstrap v 5.3

• "Cover template": light-dark toogle does not work
• "Product example": when screen is small (mobile for example), menu does not work. I click the button but nothing happens.

I am new to bootstrap and I was looking to some examples for the first time.
I am unable to solve these small bugs.
Thank you very much.

Thanks for reporting this double-issue @gipic

"Cover template": light-dark toogle does not work

This example was created to be always dark. The theme selector well changes the data-bs-theme to "light" and "dark" values. However, this example uses all the time .text-bg-dark to define the background as dark in all cases. So this is not an issue but something created to work like this.
I can understand that it's weird that the theme selector "does nothing" but we use a generic layout where the theme selector is displayed in all the examples for now.

"Product example": when screen is small (mobile for example), menu does not work. I click the button but nothing happens.

Good catch! I've created #39657 to fix it
