Same. I thought it was neat (though a bit ridiculous) that the codepen examples are doable just with CSS, but if I saw the first call to action button on a website, I'd think it was tacky and cringey.

These sorts of things scream marketing and manipulation. Let me read your site and decide what I want to do. Don't try to distract me by annoyingly drawing my attention to the thing that will make you money.

I thought at first that codepen trying to upsell me.

These are things people are already doing in native app code, so we've got to have some web equivalents or everyone's going to be doing everything in walled gardens.
