textfield resizes after validation ?

See Customizing Validation Error Messages

Thanks for your answer but it didn’t quite solve my problem.
Sadly, it doesnt matter if i use “floating tips” or “static tips” it still keeps resizing my “required” fields to a certain length whenever they are “invalid”.
You can see the effect on customizing-validation-error-messages

No matter which one it uses, the textareas will still resize.
Why ?

As explained in the link I pointed you to, you may need may need to change the styling of the error messages to suit your particular WP theme.

The link gives some examples of how to to do this.

See also Styling Contact Form for a general explanation of styling CF7 forms using CSS.

I’ve been having the same issue, despite having used this plugin on numerous sites with the same theme (Thesis 2.1 Classic Responsive), and the floating tips changes did nothing to help – rather than fixing the issue it just changed the overall styling. Just cracked it – I added this to the CSS:

.wpcf7-form-control-wrap {
width: 100% !important;
}

Thank you very much ??
This solved the problem.
Both of you, keep up the good work.
