ReCaptcha API v2 Styling

Question

I have not had much success finding how to style Google\'s new recaptcha (v2). The eventual goal is to make it responsive, but I am having difficulty applying styling for ev

Answer 1

Just adding a hack-ish solution to make it responsive.

Wrap the recaptcha in an extra div:

Add styles. This assumes the dark theme.

// Recaptcha
.recaptcha-wrap {
    position: relative;
    height: 76px;
    padding:1px 0 0 1px;
    background:#222;
    > div {
        position: absolute;
        bottom: 2px;
        right:2px;
        font-size:10px;
        color:#ccc;
    }
}

// Hides top border
.recaptcha-wrap:after {
    content:'';
    display: block;
    background-color: #222;
    height: 2px;
    width: 100%;
    top: -1px;
    left: 0px;
    position: absolute;
}

// Hides left border
.recaptcha-wrap:before {
    content:'';
    display: block;
    background-color: #222;
    height: 100%;
    width: 2px;
    top: 0;
    left: -1px;
    position: absolute;
    z-index: 1;
}

// Makes it responsive & hides cut-off elements
#g-recaptcha {
    overflow: hidden;
    height: 76px;
    border-right: 60px solid #222222;
    border-top: 1px solid #222222;
    border-bottom: 1px solid #222;
    position: relative;
    box-sizing: border-box;
    max-width: 294px;
}

This yields the following:

It will now resize horizontally, and doesn't have a border. The recaptcha logo would get cut off on the right, so I am hiding it with a border-right. It's also hiding the privacy and terms links, so you may want to add those back in.

I attempted to set a height on the wrapper element, and then vertically center the recaptcha to reduce the height. Unfortunately, any combo of overflow:hidden and a smaller height seems to kill the iframe.
