Hi,

Try to use the following code snippet to control the width of your input field. Change the “max-width: 400px” parameter to the desired number.

.mc4wp-form .mc4wp-form-fields .custom-form-checkbox {
	width: 100%;
	flex-basis: 100%;
	max-width: 100%;
}

.mc4wp-form-fields .custom-form-input {
	max-width: 400px;
}

Thank you, but we do not distribute translations to our theme by default.

Regards
