On line 402 in css/style.css, change `.wrapper` to

    .wrapper {
        width: 100%;
        padding: 10px 0;
    }

Yes, perfect, thank you. Deployed.

You could probably also change

    @media (max-width: 550px) .content { padding: 0 5px; }

but at that point it's more of a style preference.

(also, I just signed up for a HN account for this haha)

Well I agree with your style preference, deployed.

That is what Apple used to recommend but the general approach these days is to allow the user to scale however they want as long as it doesn't break your UI, and for accessibility reasons.

Thanks! Worst practice, actually. Now I'll finishing reading the article, looks exciting! :)
