[Plugin: Contact Form 7] Size/maxlength doesn't work

I am having the same problem. I don’t seem to be able to suppress the length of the fields – they just go the entire length of the sheet.

Thanks in advance for any assistance.

You need to style the required tags with appropriate CSS as per your requirement.

But there is a field in this form for both of these fetaures, and when you enter something there it doesn’t work.

So where do I put this CSS exactly ?

You can either customize CF7 css or better to define new css rules as per requirement in your theme’s style
