Form layout, field and inputbox size with 3columms & strange pageheading

Hello,

I've got 2 questions for form https://form.jotformeu.com/63502082205343

1. On the bottom of page 1, i want to adjust certain fieldsize, i've tried with CSS buth somehow it doesnt seem to work.

For instance the field "Naam verkoper / garage" i want to make the inputbox larger? But i've tried with the CSS but i cant seem to make it larger. Also certain fields below this field, the "Postcode" field i want to make it smaller, straat field larger, and so one. It seems that once you put 3 columms that field size cant be changed as easy as in a form without columms.  Now is it for instance possible to break the page, part 1 of the page is with 3 columms, and the part below is without columms, so you can play around with field size. 

So how can i change the fields on the bottom below the orange " Contactgegevens verkoper"

Try adding this code into your CSS to increase the input width of "Naam verkoper / garage"

#input_1065.form-textbox{

 width:600px !important;

 max-width: 1000px !important;

}

To decrease the postcode width try adding this code.

#input_1051.form-dropdown{

  width: 100px !important;

}

If you know the field id, just add "!important" to override the default value.

Let us know if you need more help.

I have created a separate thread for your second question to avoid confusion.
