Classic Forms: How to have fields in the same line?

Now , If I may, How can I put the first 3 fields on the same line? (Mr,
First Name, Last name to appear under the title "Full Name")
and how to put phone number and email on same line (I will use sub-titles
in place of "Phone Number" etc.
I need to shorten the form so it will print on 1 page.

Thanks again,

You can set the alignment of both fields to right.

Here is a sample screenshot.

Let us know how it goes.

It's not working. I need the Phone number and email fields on the same line.

To clarify, you want your phone and email to be aligned to each other horizontally or vertically?

If you want your phone and email to align horizontally, you can use this css code.

#id_4{
position: absolute;
    margin-left: -40px;
 
}

Here is a sample screenshot.

But if you want your fields to look like this, you can use these custom css codes.

#id_6{
  margin-top: -50px;
}
#id_4{
position: absolute;
    margin-left: -40px;
        margin-top: -50px;
 
}
#sublabel_first {
    margin-bottom: 10px;
    margin-left: 110px;
    margin-top: -15px;
}
#first_3 {
    width: 160px !important;
    position: absolute;
    margin-top: -44px;
    margin-left: 70px;
}
#last_3 {
    width: 200px !important;
    position: absolute;
    margin-top: -64px;
    margin-left: 260px;
}
#sublabel_last{
  margin-top: -34px;
    min-height: 13px;
    margin-left: 320px;
}

Let us know how it goes.

Still needs some adjustment.
When I add your code example starting with #id_6{ ...thru the end of your
code margin-left: 320px;
}
I get the following:
Last name is off form and email and phone nuber are overlaying each other.

Please note that it's not possible to have the elements "Full name" label as well as the three fields inline due to the form's width, you must increase the form's width in order to have the 4 elements inline.

Now, if it's OK for you to change the label position then you may do the following: 

1. Change the label position for the full name field: 

2. Turn on the shrink option on the email field: 

3. You may then remove the code my colleague provided and inject the following: 

#id_3 span.form-sub-label-container {

    width: auto !important;

    display: inline-block;

}

input#input_4 {

    width: auto !important;

}

The result can be seen on this cloned form of yours: https://form.jotform.com/80718777416972 

I hope this helps. 

Still no luck. I increased the width of the form and I deleted both phone
number and email fields and
added them back again. That put both fields on the same line. I added code
to increase size so that I
could type into them . The email field increased but I seem to have no
effect on the Phone number field.
The phone number field is too small to accept (###) ###-####
Here is the phone and email CSS code:
#input_24 {
width : 200px !important;
}
#input_25_Full {
width : 200px !important;
}

Thank you for your help,

You can try to use this css code to increase the width of your Phone number field.

#input_25_full{
  width:160px!important;
}

Let us know how it goes.

I'm getting close now, but look what happens when I am designing:
Picture 1 = view on Build screen. Looks Great.
Picture 2 = view when published. Line goes off page.
I have noticed at other times that the build screen does not always show
the
same when published. This makes it very hard to design a form.

Your images did not go through, you can check this guide on how to insert screenshots in the thread.

Yes, sometimes the build screen doesn't sync correctly to your published form. Kindly,refresh your browser's cache if that happens.

We recommend to follow always the published form when creating/editing your forms.
