swearingdad on "[Plugin: Contact Form 7] Email field not styled like other form fields"

This was happening on several sites. So I copied the original CSS for each theme for the "input" and "focus" for example:

input[type=text] {
	background: #eee;
	border: solid 1px #ccc;
	padding: 6px 10px;
	border-radius: 5px;
	-webkit-appearance: none;
}

input[type=text]:focus {
	outline: none;
	background: #fff;
}

Pasted it into a child theme CSS file (or the theme's custom CSS field in the Admin area) and changed "text" to "email" eg:

input[type=email] {
	background: #eee;
	border: solid 1px #ccc;
	padding: 6px 10px;
	border-radius: 5px;
	-webkit-appearance: none;
	max-width: 240px;
}

input[type=email]:focus {
	outline: none;
	background: #fff;
}

I also found I had to add a max-width attribute.

Thanks to everyone who has helped with this - really appreciate pointing me in the right direction.
