Frame around text field

You can add some styles in your CSS. I can’t be more specific than that unless you’d share a link to your site.

You could add something like this to your CSS:

form.wpcf7-form input[type="text"],
form.wpcf7-form input[type="email"]  {
    border:solid 1px #999;
}

Try it without the quotes. Since you added it in the theme options, the quotes are being converted.

form.wpcf7-form input[type=text],
form.wpcf7-form input[type=email]  {
    border:solid 1px #999;
}

Alternatively you could try this:

.wpcf7-text, .wpcf7-email {
    border:solid 1px #999;
}
