html, sass, js

Impressive solution to this challenge! 💯

I just notice that the password container and the 'Generate' button is overflowing on small-sized screen (375px). Upon checking your css, all I can suggest are to add 'box-sizing: border-box', replace 'max-width' with 'width: 100%' and lastly resizing paddings.

* { 
 box-sizing: border-box;
/ ... other css /
}

.password-wrap label input {
    width: 100%;
    padding: 16px 16px;    Note: 'auto' is invalid when using shorthands like 'padding:' 
 / ... other css /
}

.settings button {
        width: 100%;
        padding: 16px 16px;
 / ... other css /
    }

Hope this helps you somehow. Cheers!
