Width of Recaptcha fixed at 300px

I’ve been trying to get the Recaptcha width to reduce. When I view my site on a mobile device the width is to wide for my content div container (i.e. it extends past the outer div). I’ve tried going into my local css file and adding the following styling

.rc-anchor-normal-footer {
  	float: right;
}
.rc-anchor-normal .rc-anchor-pt {
    margin: 4px 55px 0 0 !important;
    width: 200px !important;
}
.rc-anchor-normal .rc-anchor-checkbox-label {
    width: 100px !important;
}
.rc-anchor-normal .rc-anchor-content {
    width: 175px !important;
}

If I put these settings in with the developer tool in my browser it works great but when I refresh is disappears. It looks like it is getting the styling from google and ignoring my local styles. Is there a way to reduce the width?

Thank you for any help you can provide.
