Good evening in France

I try to reduce the length of this input .I use the trick you already send me but it does not works.I don't know why.( in green . form-line is displayed !!)

I see this is about form 60645160566355, named message aux chauffeurs.

On this form, the field that is marked in green is field named "fdate de fin du transport( si transports multiples)". This field has the ID of 54, so the CSS code to change the width of this field would be:

#id_54 { max-width: 300px; }

Image without the code:

Image after applying the code:

You can find out the ID of the field by following this guide:
